Yields: 1 dozen muffins

2 cups all-purpose flour
1/3 cup granulated sugar
2 tsp baking powder
1/2 tsp kosher salt
3 Tbsp unsalted butter, melted
1/2 cup peanut butter
1 cup whole milk
1large egg, beaten
3/4 cup chocolate chips

Preheat oven to 350°. Combine the flour, sugar, baking powder, and salt in a large mixing bowl. In a separate medium sized bowl, whisk together the butter, sugar, peanut butter, eggs, and milk. Pour the wet ingredients into the dry and stir just until combined; fold in the chocolate chips.

Coat a nonstick muffin pan with cooking spray (or line with muffin liners). Fill each muffin cup about 3/4 full with batter. Bake 15-20 minutes or until light golden brown. Cool on a wire rack. Best served same day.
