Preheat oven to 350°F.

Spray a 9”x5” loaf pan with nonstick baking spray; set pan aside. (Optional: Line pan with parchment paper for easy removal of bread once baked.)

Using a medium mixing bowl, add flour, pudding mix, baking powder, baking soda and salt; stir until well combined. Set dry ingredients aside.

In a separate bowl, add oil, sour cream, eggs, vanilla extract and milk; whisk together until well combined. Set wet ingredients aside.

Using a large bowl, add brown sugar and peanut butter; stir until well combined.

Add half of the dry ingredients to the bowl; stir until well combined.

Add half of the wet ingredients to the bowl; stir until well combined.

Repeat using remaining dry and wet ingredients.

Transfer batter into prepared loaf pan. Sprinkle peanut butter baking chips on top of batter.

Bake for 50 minutes. Tent top of bread with foil and continue baking for 15-20 minutes, or until a toothpick inserted into center of bread comes out mostly clean.

Let bread cool in pan for 15 minutes before transferring to a cooling rack until completely cool.
