Ever want to take your jar of peanut butter and eat it like it’s cereal? And by cereal I mean you eat it by the spoonful until everything in your jar is gone? Well, this peanut butter filling will satisfy your craving and luckily doesn’t have nearly as many calories.
And don’t be scared by the prunes in the chocolate cupcake. You won’t even notice the flavor but they give the cupcakes a great texture and consistency, as well as good-for-you fiber and antioxidants! Mmmm…antioxidants.

- 1/4 tsp butter extract
Instructions
- Preheat oven to 325 F
- For the cupcakes - Place water in a microwavable safe cup or bowl. Microwave until warm, but not boiling.
- Add prunes (or dates) to the warm water and soak for 5 minutes.
- In a medium bowl, add the oat flour, protein powder, salt, baking soda and powder, cocoa, and sweetener.
- Transfer soaked prunes and water to a blender or food processor and blend until a thick liquid consistency.
- Add prune paste to dry ingredients, along with milk, egg whites, and vanilla extract.
- Stir to combine until all the dry ingredients are moistened.
- Fill greased or lined cupcake pan 2/3 way full with dough.
- Bake cupcakes for 15 minutes or until a toothpick inserted into center of cupcake comes out clean.
- Allow cupcakes to cool in pan.
- For filling - Mix together protein powder, powdered peanut butter, sugar, milk, and water together until smooth.
- For icing: In a large bowl, combine cocoa, flax seed, sugars, Greek yogurt, milk, vanilla and butter extract with electric mixer or whisk until thick and smooth consistency.
- Scoop out middle of cooled cupcakes. Fill hollowed cupcakes with peanut butter filling (I found it easiest to scoop up some filling with a spoon and gently drizzle it into the hollowed cupcakes).
- Place icing in a ziplock bag. Cut a tiny bit off one of the bottom ends of the ziplog bag. Pipe the icing onto peanut butter filled cupcakes.
- Time to eat!
