Ingredients Breakdown
For the Cake Base:
- 1 cup plain Greek yogurt – Full-fat or 2% works best for moisture and texture
- 2 large eggs – Binds the ingredients and provides structure
- 1/2 cup natural peanut butter – Smooth and unsweetened
- 1/4 cup honey or maple syrup – Natural sweetener without refined sugar
- 1 teaspoon vanilla extract – For warmth and depth of flavor
- 1 cup oat flour – Ground oats, naturally gluten-free
- 1/2 teaspoon baking soda – Helps the cake rise gently
- 1/2 teaspoon baking powder – Adds extra lift
- 1/4 teaspoon sea salt – Balances the sweetness
For the Chocolate Fudge Topping:
- 1/2 cup dark chocolate chips – Rich, semi-sweet or 70% cocoa
- 2 tablespoons natural peanut butter – For extra creaminess
- 2 tablespoons Greek yogurt – Makes the topping silky
- 1 tablespoon maple syrup – Adds a hint of sweetness
Step-by-Step Instructions
Step 1: Preheat the Oven
Set your oven to 350°F (175°C). Line an 8x8-inch baking pan with parchment paper or lightly grease it with coconut oil.
Step 2: Mix Wet Ingredients
In a large mixing bowl, whisk the Greek yogurt, eggs, peanut butter, honey (or maple syrup), and vanilla extract until creamy and smooth. Make sure there are no lumps.
Step 3: Combine Dry Ingredients
In a separate bowl, whisk together the oat flour, baking soda, baking powder, and salt. Gradually add the dry mixture into the wet ingredients. Stir gently until everything is well incorporated.
Step 4: Bake the Cake
Pour the batter into your prepared pan. Spread it evenly using a spatula. Bake for 25–30 minutes. The top should be golden, and a toothpick inserted in the center should come out clean.
Allow the cake to cool completely in the pan before adding the topping.
Step 5: Make the Fudge Topping
Place the chocolate chips in a microwave-safe bowl. Heat in 30-second intervals, stirring between each session, until fully melted. Add the peanut butter, Greek yogurt, and maple syrup. Mix until silky and smooth.
Step 6: Frost the Cake
Spread the fudge topping evenly over the cooled cake. Let it set in the refrigerator for at least 30 minutes before slicing.
