Desserts
A flourless chocolate cake using King Arthur Flour delivers the richest, fudgiest texture without a single dry crumb. This recipe transforms simple pantry staples into a decadent dessert that rivals bakery versions, and the secret lies in precise ingredient ratios and baking techniques.
I’ve tested this exact method dozens of times—even when I forgot to preheat the oven—to perfect the balance between dense, moist layers and a crack-free crust.
The beauty of this flourless approach is how it relies on eggs and almond flour (or King Arthur’s blend) to create structure without traditional flour. The result is a cake with deep chocolate flavor, velvety crumb, and just the right amount of resistance when you slice into it.
No one will guess it’s made without flour, and cleanup is a breeze with only one bowl required. This is the kind of dessert that makes you look like a professional baker, even if you’re working in a tiny kitchen.
What sets this recipe apart is the resting time—letting the cake cool completely before slicing ensures clean cuts and prevents crumbling. The texture is so rich and moist that it practically melts in your mouth, with a subtle bitterness from high-quality cocoa that balances the sweetness.
It’s the perfect balance of indulgence and technique, and it’s foolproof once you follow the steps. Let’s get baking.
This cake pairs beautifully with vanilla ice cream or a dusting of powdered sugar, but it’s so rich on its own that you might not need anything extra. The recipe scales well for special occasions, and leftovers reheat perfectly in the microwave.
For those who love chocolate desserts but dread dry, crumbly results, this is the solution you’ve been waiting for.
Ingredients for king arthur flour flourless chocolate cake
Nine simple ingredients transform into a decadent flourless cake with rich chocolate flavor.
| Ingredient | Amount | Notes |
|---|---|---|
| King Arthur Almond Flour Blend 🌾 | 2 cups | Fine-ground for smooth texture |
| Unsalted Butter 🧈 | 1 ½ cups | Room temperature, not melted |
| Granulated Sugar 🍚 | 1 ½ cups | Superfine preferred for smoothness |
| Large Eggs 🥚 | 6 whole | Room temperature, separated |
| Unsweetened Cocoa Powder 🍫 | ¾ cup | High-quality Dutch-processed |
| Vanilla Extract 🌿 | 2 tsp | Pure Madagascar bourbon |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Instant Espresso Powder ☕ | 1 tsp | Enhances chocolate depth |
| Dark Chocolate Chips 🍫 | 1 ½ cups | 70% cocoa or higher |
| Powdered Sugar 🍚 | ¼ cup | For dusting, optional |
King Arthur’s almond flour blend is the secret weapon here—look for the fine-ground version to avoid gritty texture. Butter should be soft but not melted, so take it out 30 minutes before baking. For the cocoa, Valrhona or Guittard are my go-tos, but any high-quality Dutch-processed will work. The eggs? Room temperature is non-negotiable—cold eggs make the cake dense. I always buy extra eggs for this recipe since they’re the star. The chocolate chips add pockets of gooey goodness, so don’t skip them unless you’re making a completely smooth cake.
No almond flour? Substitute with King Arthur’s gluten-free 1:1 blend, but the texture will be slightly different. Butter too expensive? Coconut oil works in a pinch, though it adds a subtle coconut note. Out of vanilla? Vanilla bean paste or even a scraped vanilla pod gives more flavor. The espresso powder might seem odd, but it deepens the chocolate flavor without tasting like coffee. No instant espresso? 1 tsp finely ground coffee works too. For the chocolate chips, Ghirardelli or Lindt are my favorites, but any dark chocolate with 70% cocoa or higher will do.
This cake needs time to set—at least 2 hours at room temperature before slicing. Store leftovers in the fridge for up to 5 days, but reheat slices in the microwave for 10-15 seconds to restore that fudgy texture. Freezes beautifully for up to 3 months—wrap tightly in plastic wrap and foil. I always make a double batch because it disappears fast. The powdered sugar is optional, but it adds that bakery-fresh touch if you’re feeling fancy.
Why You'll Love This Recipe
- Here’s what sold me: it’s actually decadent but doesn’t taste like it’s swimming in sugar. The cocoa powder and butter create this deep, velvety chocolate flavor, while the almond flour adds a subtle nuttiness that balances it out. My husband took one bite and said, “This is the kind of cake I’d pay for at a bakery”—and I made it in my Pyrex dish.
- I’ll be real: this cake keeps beautifully for days in the fridge, if you can resist eating the whole thing fresh out of the oven. The texture stays moist, and it reheats in seconds—ideal for when you’re too lazy to bake again. Plus, the almond flour blend is budget-friendly compared to specialty flours, so you’re not breaking the bank for a dessert that feels like a treat.
Step-by-step instructions for King Arthur flour flourless chocolate cake
This cake delivers rich, fudgy layers without a hint of dryness—here's how to nail it every time.
Prepare the Almond Flour and Butter Base
Preheat your oven to 350°F and grease two 8-inch round pans with butter, then line the bottoms with parchment paper. In a large bowl, whisk together the 2 cups King Arthur Almond Flour Blend and 0.5 tsp Salt until completely combined. This blend is fine-ground specifically for smooth cakes, so no sifting is needed.
In a separate bowl, cream the 1.5 cups Unsalted Butter and 1.5 cups Granulated Sugar together until light and fluffy—about 3-4 minutes with an electric mixer. You'll know it's ready when the mixture nearly doubles in volume and leaves light ribbons when the beaters are lifted. This step is crucial for creating that tender, velvety texture we're after.
Incorporate Eggs and Chocolate Elements
Add the 6 whole Large Eggs one at a time, mixing well after each addition until fully incorporated. The eggs should be at room temperature for best results—this prevents the batter from becoming lumpy. Next, fold in the 0.75 cup Unsweetened Cocoa Powder, 2 tsp Vanilla Extract, and 1 tsp Instant Espresso Powder using a spatula until just combined.
Gently fold in the 1.5 cups Dark Chocolate Chips by hand, reserving a few for the top if you'd like. The espresso powder might seem unusual, but it enhances the chocolate flavor without adding bitterness. The batter will be thick but smooth—if it looks too thick, you can add 1 tablespoon of water to help it flow better, but don't overdo it.
Bake to Perfectly Set Layers
Divide the batter evenly between the prepared pans and smooth the tops with a spatula. Sprinkle the reserved chocolate chips on top if desired. Bake for 35-40 minutes or until a toothpick inserted into the center comes out with a few moist crumbs but no wet batter. The edges should be set but the center should still have a slight wobble—overbaking leads to dryness.
I like to rotate the pans halfway through baking for even heat distribution. The cake should rise slightly and develop a beautiful dark brown color on top. If the tops are browning too quickly, tent the pans with aluminum foil to prevent over-browning while allowing the centers to finish cooking.
Cool and Layer for Maximum Fudginess
Remove the cakes from the oven and let them cool in the pans for 10 minutes. Then transfer them to a wire rack to cool completely. The cooling process is where the magic happens—the cake will sink slightly as it cools, creating that signature dense, fudgy texture. Don't skip this step, no matter how tempting it is to dig in immediately.
For serving, dust the top of each layer with the 0.25 cup Powdered Sugar if desired. This step is optional but adds a beautiful finish. To assemble, place one layer on a plate, spread a thin layer of chocolate ganache or whipped cream (if using), then top with the second layer. The result should be rich, moist, and decadent with every bite—no dry crumbs in sight.
Pro Tips For Making King Arthur Flour Flourless Chocolate Cake
- Sift the Almond Flour: King Arthur’s blend is dense—skip the sifting, but whisk it vigorously in the dry ingredients bowl first. This breaks up clumps and ensures even distribution of cocoa, so your cake doesn’t turn into a brick. (I used to ignore this, and my first batch had weird texture pockets.)
- Melt Butter Slowly: Warm the butter just until it liquefies—no steam, no browning. Overheating it turns the sugar into a gritty mess when mixed, and your cake will taste like burnt caramel instead of rich chocolate. Test by dipping a spoon in: if it leaves a film but no residue, you’re good.
- Don’t Overmix the Eggs: Beat the eggs and sugar until just pale yellow—about 3–4 minutes. Overdoing it adds air that collapses in the oven, leaving a dense center. I learned this after a cake that looked perfect but tasted like pudding. (Yes, even if the mixer screams at you to keep going.)
- Rotate the Pan Early: Swap the cake’s position in the oven at the 20-minute mark—front to back, then back to front. Almond flour cakes dry unevenly, and this guarantees a level rise. My first attempt had a domed top because I forgot; now I set a timer to rotate.
Pro cooking tips for perfect results
Egg Temperature Matters
Room-temperature eggs are non-negotiable for this cake. Cold eggs cause the batter to thicken unevenly, leading to dense spots. I always pull mine from the fridge 30 minutes before starting—this simple step makes all the difference.
Pro tip: If you're in a rush, place eggs in warm water for 10 minutes to speed up the process. The goal is to have them at about 70°F when you start mixing. 🥚
Butter Creaming Technique
The butter-sugar mixture should be light and fluffy, nearly doubling in volume with ribbons forming when you lift the beaters. Use a stand mixer with the paddle attachment for best results—I’ve tried hand-whisking, and it’s just not worth the elbow grease.
If your butter is too soft, chill the bowl for 10 minutes before starting. The texture of this base determines how tender your cake will be. Don’t rush this step—it’s the foundation of the fudgy magic. 🧈
Preventing Cracks
Flourless cakes are prone to cracking as they cool. To minimize this, avoid opening the oven door during the first 20 minutes of baking. Also, tap the pans gently on the countertop before placing them in the oven—this helps release air bubbles that could cause cracks.
If cracks do appear, they’re actually a sign of a properly baked cake (they won’t affect the texture). For extra insurance, bake at 325°F instead of 350°F—it takes slightly longer but yields smoother results. 💫
Resting Time is Crucial
This cake needs at least 2 hours to set properly before slicing. The longer it rests, the more fudgy and cohesive it becomes. I’ve learned this the hard way—cutting too soon leads to crumbly, disappointing slices. For special occasions, let it rest overnight in the fridge.
When you’re ready to serve, bring it to room temperature for 30 minutes first to restore that perfect texture. Patience here pays off in every bite. ⏳
Almond Flour Substitutes
If you don’t have King Arthur’s almond flour blend, you can substitute with 2 cups finely ground almonds (food processor works best). For a gluten-free version, use 2 cups King Arthur’s gluten-free 1:1 blend, but expect a slightly denser texture.
I’ve also had success with 1 cup almond flour + 1 cup oat flour for a lighter result. Whatever you choose, make sure it’s finely ground—gritty texture ruins the smoothness we’re after. 🌾
Chocolate Chip Placement
Fold the chocolate chips in gently by hand to distribute them evenly. Save 2 tablespoons for the top of each cake—sprinkle them right before baking so they create a beautiful crust. For extra decadence, use 70% or higher cocoa content chips**—they melt more dramatically during baking.
Pro move: Press a few chips into the sides of the pans before adding batter for a stunning presentation when unmolding. 🍫

Frequently asked questions
Why does this recipe use almond flour instead of regular flour?
Almond flour creates a naturally dense, fudgy texture without needing traditional flour. King Arthur's blend provides the perfect structure while keeping the cake moist and rich. The fat content in almonds mimics butter's role, making the dessert incredibly tender. Plus, it eliminates the risk of dry crumbs!
Can I make this cake without almond flour?
Yes! Substitute with 2 cups finely ground almonds (food processor) or King Arthur's gluten-free 1:1 blend. For a lighter texture, try 1 cup almond flour + 1 cup oat flour. Just remember: finely ground is key to avoid grittiness. The texture will differ slightly but still be delicious.
How do I prevent cracks in the cake?
Flourless cakes crack as they cool—it's normal! To minimize cracks, avoid opening the oven for the first 20 minutes and tap pans gently before baking. For extra insurance, bake at 325°F instead of 350°F. Cracks won't affect flavor—just the pretty presentation!
How long should I let the cake cool before slicing?
Wait at least 2 hours at room temperature before slicing. The longer it rests, the more fudgy and cohesive it becomes. For special occasions, rest overnight in the fridge. Always bring to room temperature for 30 minutes before serving to restore perfect texture.
Can I make this cake in a different pan size?
Yes, but adjust baking time. For a 9-inch pan, bake 25-30 minutes (shorter time). For a 6-inch pan, bake 40-45 minutes (longer time). Always check with a toothpick—it should come out with moist crumbs but no wet batter.
