Ingredients (Makes 12 servings):
For the Cake:
- 1 1/2 cups whole wheat flour
- 1/2 cup granulated sweetener (like Stevia or Monk Fruit)
- 1 tsp baking powder
- 1/2 tsp baking soda
- 1/2 tsp salt
- 1/4 cup unsweetened applesauce
- 1/2 cup low-fat buttermilk (or regular milk)
- 2 large eggs
- 1/4 cup peanut butter (light, or use powdered peanut butter for fewer points)
- 1 tsp vanilla extract
For the Frosting:
- 1/4 cup reduced-fat peanut butter
- 1/4 cup light cream cheese, softened
- 1/4 cup powdered sweetener (like Stevia or Monk Fruit)
- 1/2 tsp vanilla extract
- 2 tbsp unsweetened almond milk (or regular milk)
- Pinch of salt
Instructions:
Step 1: Preheat the Oven
- Preheat your oven to 350°F (175°C).
- Grease a 9×13-inch baking pan or line it with parchment paper.
Step 2: Prepare the Cake Batter
- In a large mixing bowl, whisk together the whole wheat flour, sweetener, baking powder, baking soda, and salt.
- In a separate bowl, beat the eggs, applesauce, buttermilk, peanut butter, and vanilla extract until well combined.
- Gradually add the wet ingredients to the dry ingredients, mixing until just combined. The batter will be slightly thick.
Step 3: Bake the Cake
- Pour the cake batter into the prepared baking pan and spread it out evenly.
- Bake for 25–30 minutes, or until a toothpick inserted into the center comes out clean.
- Allow the cake to cool completely in the pan on a wire rack.

Step 4: Make the Frosting
- In a medium bowl, beat together the reduced-fat peanut butter, cream cheese, powdered sweetener, vanilla extract, and milk.
- Continue beating until smooth and creamy. If the frosting is too thick, add a little more milk to reach the desired consistency.
Step 5: Frost the Cake
- Once the cake is completely cool, spread the peanut butter frosting evenly over the top of the cake.
Step 6: Serve and Enjoy
- Cut the cake into 12 servings and enjoy!
- Store any leftovers in an airtight container in the fridge.
Tips:
- Reduce Sweetness: If you prefer a less sweet frosting, reduce the powdered sweetener in the frosting by half.
- Nutty Addition: Add a handful of chopped peanuts on top for a crunchy texture.
- Make it Gluten-Free: Use a gluten-free flour blend to make the cake gluten-free.
