What Is a Flourless Black Cocoa and Chia Greek Yogurt Cake?

This isn’t your ordinary chocolate cake. It’s made with black cocoa powder — the same deep, dark cocoa that gives Oreo cookies their signature flavor — plus chia seeds for structure and Greek yogurt for that luscious moisture.

The result? A cake that’s gluten-free, naturally rich in protein, and utterly decadent. Think of it as the love child between a brownie and a dark chocolate truffle — smooth, rich, and slightly tangy.

Why You’ll Love This Recipe

• 🍫 Deep chocolate flavor: Thanks to black cocoa, it’s intense and aromatic.
• 🌱 Naturally gluten-free: No flour needed — chia seeds do the work!
• 💪 Protein-packed: Greek yogurt keeps it wholesome and satisfying.
• 🧁 One bowl recipe: Minimal mess, maximum reward.
• 💕 Guilt-free indulgence: Lower in sugar, higher in nutrients.

The Taste

One bite, and you’ll be amazed. The black cocoa gives a dark, bittersweet chocolate flavor, while the Greek yogurt adds subtle tang and creaminess. The chia seeds bind everything together for a soft, moist crumb that feels decadent — but with a light, wholesome aftertaste.

This cake tastes incredible on its own, but a dollop of whipped Greek yogurt or a drizzle of melted dark chocolate takes it over the top.

How to Make Flourless Black Cocoa and Chia Greek Yogurt Cake

Step 1: Preheat and prepare Preheat oven to 350°F (175°C). Line an 8-inch pan with parchment paper and lightly grease it.

Step 2: Mix wet ingredients In a bowl, whisk together Greek yogurt, eggs, honey (or maple syrup), and vanilla extract until smooth.

Step 3: Add dry ingredients Sift in black cocoa, baking powder, and salt. Stir until combined. Then fold in chia seeds (and chocolate chips, if using).

Step 4: Let the batter rest Allow the mixture to sit for about 10 minutes — this gives the chia time to thicken and bind the batter.

Step 5: Bake Pour the batter into your prepared pan and bake for 25–30 minutes, or until the center is set and a toothpick comes out mostly clean.

Step 6: Cool and serve Cool completely before slicing. Serve as-is or with a spoonful of Greek yogurt and a dusting of cocoa powder.
