Step‑by‑Step Instructions for Peanut Butter Protein Cake with Chocolate Fudge
Step 1: Preheat and Prepare the Baking Pan
Begin by preheating your oven to 350°F (175°C). While the oven heats up, take an 8×8 inch baking pan and line the bottom and sides with parchment paper, allowing some overhang for easy removal later. This step ensures your Peanut Butter Protein Cake releases easily after baking, so you get to enjoy every delicious bit.
Step 2: Mix Wet Ingredients
In a large mixing bowl, combine 1 cup of Greek yogurt, 1 cup of peanut butter, ½ cup of honey, 2 room-temperature eggs, and 1 teaspoon of vanilla extract. Whisk the ingredients together until completely smooth and creamy, taking about 2-3 minutes. This mixture will provide the base for your cake, giving it rich flavor and moisture.
Step 3: Incorporate Dry Ingredients
Gradually add in 1 cup of oat flour, ¼ cup of protein powder, 1 teaspoon of baking powder, and a pinch of salt to the wet mixture. Using a spatula, gently fold until just combined, being careful not to overmix to keep your Peanut Butter Protein Cake tender. This should take about 1-2 minutes.
Step 4: Pour and Smooth the Batter
Carefully pour the batter into the prepared baking pan and use a spatula to smooth the surface evenly. Make sure to spread it out to the edges for uniform baking. Once smooth, place the pan in the preheated oven and bake for 18-20 minutes, or until the edges are set and the center jiggles slightly when moved.
Step 5: Cool the Cake
After baking, remove the pan from the oven and let the cake cool in the pan for about 10 minutes. This cooling period allows the cake to firm up slightly, making it easier to handle. While it cools, you can prepare the chocolate fudge topping for your Peanut Butter Protein Cake.
Step 6: Prepare the Chocolate Fudge Topping
In a medium bowl, whisk together ¼ cup of cocoa powder, ½ cup of Greek yogurt, and your choice of sweetener, like maple syrup. Mix until you achieve a smooth, velvety consistency. This fudge will add a rich chocolate layer to your cake, elevating its overall taste and appearance.
Step 7: Apply the Topping and Chill
Once the cake is slightly cooled, carefully spread the chocolate fudge topping over the warm cake using a spatula. Ensure that the topping covers the entire surface. Place the cake in the refrigerator and chill for at least 30 minutes to allow the fudge to set properly, ensuring a beautifully firm finish.
Step 8: Slice and Serve
After the cake has chilled and the topping is set, use the parchment paper overhang to lift the cake out of the pan. Place it on a cutting board and slice into squares. Your Peanut Butter Protein Cake with Chocolate Fudge is now ready to be enjoyed as a nutritious treat that’s perfect for any time of the day!

Peanut Butter Protein Cake with Chocolate Fudge Recipe FAQs
What kind of Greek yogurt should I use for the cake?
Absolutely use full-fat Greek yogurt for this recipe! It provides the best moisture and creaminess to keep the cake tender. If you prefer a lower fat option, non-fat Greek yogurt will work, though the texture may be slightly less rich.
How should I store leftovers of the Peanut Butter Protein Cake?
Store your Peanut Butter Protein Cake in an airtight container in the refrigerator for up to one week. This ensures the cake stays fresh and maintains its moist texture. Always let it cool to room temperature before refrigeration to avoid condensation.
Can I freeze this Peanut Butter Protein Cake?
Yes! For long-term storage, wrap individual slices tightly in plastic wrap or aluminum foil and freeze for up to three months. When you’re ready to enjoy a slice, thaw it overnight in the fridge or at room temperature for about an hour.
What if my cake is too dense?
If you find your cake comes out too dense, ensure you didn’t overmix the batter after adding the dry ingredients—that’s the key! Also, check that you didn’t use too much protein powder, as it can significantly affect the texture. Next time, fold gently and be cautious with ingredient measurements.
Can this recipe accommodate dietary restrictions?
Very! If you’re allergic to peanuts, you can easily substitute almond butter or sunflower seed butter for the peanut butter. Additionally, to make it completely dairy-free, use non-dairy yogurt alternatives. Just stick to gluten-free oat flour or blended rolled oats to keep the cake gluten-free.
Is this recipe suitable for pets as a treat?
While this cake is nutritious for humans, it’s not suitable for pets due to the high honey and nut content. Always consult your vet before sharing human food with your furry friends!
