Step 1 - Prep. Preheat oven to 400 degrees. Lightly spray the donut pan with baking spray. Set pan aside.

Step 2 - Prepare the donuts. In a large bowl, whisk together flour, baking powder, baking soda, cinnamon, salt and sugar. In a separate bowl, whisk together milk, sour cream, and eggs. Whisk in the melted butter, oil and vanilla. Gradually whisk the wet ingredients into the dry ingredients, adding chopped peanut butter cups and stir just until combined.

Step 3 - Bake the donuts. Transfer the batter equally into the donut pan either with a spoon or piping bag until each hole is ⅔ full. Bake donuts for about 9-10 minutes allowing to cool before removing from pan. Once cooled remove from pan and transfer to a wire rack.

Step 4 - Add the chocolate topping. Add chocolate chips to a small microwave safe bowl and microwave in 30 second increments until melted and smooth. Allow chocolate to thicken a bit. Dip each donut into the chocolate allowing the excess to drip off. Place on wire rack and allow chocolate to set.

Step 5 - Drizzle with peanut butter & garnish. Add peanut butter to a small microwave safe bowl and microwave in 30 second increments until is melted and smooth. Drizzle melted peanut butter over top donuts using a spoon. Add chopped peanut butter cups. Allow to harden and enjoy.
