Peanut butter galore! These cupcakes do not skimp out on the peanut butter flavor. These cupcakes are also packed with protein since I used two products from the Lean Body for Her protein line (the vanilla whey concentrate and the peanut protein) along with all natural peanut butter. The smooth icing is loaded with peanut butter flavor also! Since these are more nutrient dense, I only treated myself to one so far. It was delicious and I STILL wanted another one. Good thing this recipe makes 6 total. Enjoy!
