Step 1
Start by heating your oven to 350°F (175°C) and line a 12-cup muffin pan with paper liners. In a big bowl, whisk together the flours, baking powder, baking soda, and salt. In a small saucepan, melt the butter over low heat, then stir in the peanut butter and brown sugar until smooth. Take it off the heat and mix in the milk, egg, and vanilla extract. Pour this wet mixture into the dry ingredients and stir just until everything is combined—if the batter feels too thick, add a splash of milk, a tablespoon at a time. Fold in the chopped apples and peanut butter chips gently so they’re evenly spread throughout. Spoon the batter into the muffin cups, filling them up evenly, and pop them in the oven. Bake for about 20 minutes, or until a toothpick stuck in the center comes out clean. Let them cool a bit before digging in!
