These Peanut Butter Muffins with chocolate chips are soft, fluffy and super easy to make. Full of peanut butter flavor with hints of chocolate, they're the perfect breakfast, snack or lunchbox item!
Preheat oven to 375°F and line standard muffin pans with paper liners or grease them well with nonstick cooking spray.
In a stand mixer with paddle attachment or with hand beaters and large mixing bowl, cream together: butter, peanut butter, brown sugar and white sugar until light and fluffy.
Add the eggs one at a time, beating well after each egg.
Next, add the vanilla extract and milk, mix on low speed until fully combined.
Now, add the baking powder, salt and all purpose flour. Mix on low speed just until incorporated.
Fold in mini chocolate chips.
Using a large scoop, fill muffin cups ¾ full. Add a few extra chocolate chips on top for a pretty muffin.
Bake muffins for 18-20 minutes or until toothpick inserted in center comes out clean.
Let muffins cool in pan for 5 minutes then remove to wire rack and cool completely.
