Step 1

Preheat oven to 375°F. Liberally grease a standard muffin tin with cooking spray. Set aside.

In a large bowl, combine the butter and sugar until it resembles soft, wet crumbles. Add in the egg, then egg white, whisking after each addition (for this, I simply used a fork — but you could use a handheld electric mixer if desired). Whisk the mixture quickly until it is light and fluffy.

Beat in the buttermilk, water, vinegar and vanilla until just combined. Lastly, add the flour, cocoa, baking soda and salt until moistened. Stir in the chocolate chips.

Evenly portion the batter among the muffin cups, about 3/4 of the way full. Bake for approximately 13 to 15 minutes or until a toothpick inserted near the center comes out clean or with moist crumbs; do NOT over bake!

Cool for a few minutes in the pan before gently transferring them to a wire rack. Put parchment of a paper towel under the rack to help with the mess, then drizzle the tops of the muffins evenly with the peanut butter. Serve!
