Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
1 cup oat flour
1/2 cup chocolate protein powder
1/3 cup unsweetened cocoa powder
3/4 cup granulated sugar or coconut sugar
1 teaspoon baking powder
1/2 teaspoon baking soda
1/4 teaspoon salt
2 large eggs
3/4 cup Greek yogurt
1/2 cup milk of choice
1/3 cup melted butter or neutral oil
1 teaspoon vanilla extract
1/2 cup dark chocolate chips
For the chocolate topping:
1/2 cup dark chocolate
1/4 cup heavy cream
Directions
Preheat your oven to 180°C (350°F) and lightly grease an 8-inch round cake pan or line it with parchment paper.
In a large mixing bowl, combine the oat flour, chocolate protein powder, cocoa powder, sugar, baking powder, baking soda, and salt. Whisk until evenly mixed.
In a separate bowl, whisk together the eggs, Greek yogurt, milk, melted butter, and vanilla extract until smooth and well combined.
Gradually pour the wet ingredients into the dry ingredients, stirring gently until a thick batter forms. Avoid overmixing to keep the cake soft and tender.
Fold in the chocolate chips, ensuring they are evenly distributed throughout the batter.
Pour the batter into the prepared cake pan and smooth the top with a spatula.
Bake for 25 to 30 minutes, or until a toothpick inserted into the center comes out with just a few moist crumbs.
Allow the cake to cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely.
To prepare the topping, heat the cream until warm (not boiling), then pour it over the chopped dark chocolate. Let it sit for a minute, then stir until smooth and glossy.
Spread the chocolate topping over the cooled cake. Let it set slightly before slicing and serving.

Variations
You can customize this cake in several ways. Swap oat flour with almond flour for a lower-carb option, or use whole wheat flour for a more traditional texture. Add a teaspoon of instant coffee to enhance the chocolate flavor. For a fruit twist, fold in raspberries or sliced strawberries. If you prefer a dairy-free version, substitute the Greek yogurt with a plant-based yogurt and use almond or oat milk.
Storage/Reheating
Store the cake in an airtight container in the refrigerator for up to 5 days. The texture stays moist and the flavor deepens over time.
To reheat, place a slice in the microwave for about 10–15 seconds to restore its soft and slightly gooey texture. You can also enjoy it cold for a denser, fudgier bite.
For longer storage, freeze individual slices wrapped tightly for up to 2 months. Thaw overnight in the refrigerator before serving.
