Fluffy peanut butter muffins embedded with a gooey dark chocolate peanut butter cup. A peanut butter and chocolate lovers dream.
Preheat the oven to 350 degrees. Line a muffin tin with muffin liners.
In a large mixing bowl, whisk together peanut butter, non-dairy milk, vanilla, and sugars until creamy. Add flour, baking soda and powder, spices, and salt. Use a wooden spoon or spatula to stir batter until combined and no flour is visible. Use a cookie scoop to fill each muffin liner ½ full. Press one peanut butter cup into the center and top with 1 tbsp muffin batter making sure the chocolate is completely covered.
Bake muffins for 25 minutes. Transfer to a wire cooling rack to cool completely before frosting, if desired.
