Ingredients

For the cake base:

½ cup Greek yogurt (full-fat recommended for richness)
½ cup natural peanut butter (drippy style works best)
¼ cup honey or maple syrup (adjust to taste)
2 large eggs (room temperature preferred)
1 teaspoon vanilla extract
½ cup oat flour (easily made by blending rolled oats)
2 scoops vanilla or peanut butter protein powder (about 50-60g total)
½ teaspoon baking powder
¼ teaspoon fine sea salt

For the fudge topping:

¼ cup Greek yogurt
2 tablespoons peanut butter
2 tablespoons unsweetened cocoa powder
1-2 teaspoons honey
Optional: sprinkle of crushed nuts for crunch

Ingredient tips:

For gluten-free: Ensure your oat flour and protein powder are certified gluten-free.

For dairy-free: Substitute Greek yogurt with coconut yogurt and use a dairy-free protein powder.

Step-by-Step Instructions

Prep Your Pan and Oven
Preheat your oven to 350°F (175°C) and line an 8×8-inch pan with parchment paper, leaving overhang on two sides. This ensures easy removal and clean slices later. The parchment is crucial because the Greek Yogurt Peanut Butter Protein Cake with Chocolate Fudge Topping contains minimal oil, making it more prone to sticking.
Create the Wet Base
In a large mixing bowl, beat together the Greek yogurt, peanut butter, honey, eggs, and vanilla extract for 3-4 minutes. This creates a smooth, emulsified base that contributes to the cake's tender crumb. A hand mixer works best, but vigorous whisking by hand also achieves good results.
Incorporate Dry Ingredients
Add the oat flour, protein powder, baking powder, and salt to the wet mixture. Mix just until combined – overmixing leads to toughness. The batter will be thick but spreadable, resembling traditional pound cake batter.
Bake to Perfection
Transfer batter to the prepared pan, smoothing the top with a spatula. Bake for 18-20 minutes until edges pull away slightly and the center springs back when lightly touched. It may look slightly underdone, but carryover cooking will finish it.
Prepare the Fudge Topping
While the cake cools slightly, whisk together all topping ingredients in a small bowl. Start with 1 teaspoon honey, then adjust sweetness as desired. The mixture should be thick but spreadable.
Assemble and Set
Spread the fudge topping over the warm cake – the residual heat helps it adhere beautifully. Sprinkle with crushed nuts if using, then chill for at least 30 minutes to set the topping before slicing into 9-12 squares.

Common Mistakes to Avoid

Overbaking leads to dryness – remember the center should seem slightly underdone when removing from oven.
Using thick or cold peanut butter makes blending difficult – warm it slightly if needed.
Skipping the parchment paper causes difficulty removing slices cleanly.
Overmixing after adding dry ingredients develops gluten, resulting in a dense texture.
Applying topping to cold cake makes spreading challenging – assemble while still slightly warm.

Storage Tips

Refrigeration: Store covered in the refrigerator for up to 5 days. The flavors actually improve after 24 hours.

Freezing: Slice completely cooled cake and wrap portions individually. Freeze for up to 2 months. Thaw overnight in the refrigerator.

Reheating: For warm cake, microwave individual slices for 10-15 seconds. The topping may soften slightly.
