Preheat oven to 350. Line a 12-cup muffin tin with liners (this recipe makes about 10 mini monkey breads).
Cut each biscuit into 4-5 pieces (depending upon how large each biscuit is).
Flatten each piece in the palm of your hand and place 2 dark chocolate chips and 2 peanut butter chips in the center. Fold the dough completely around the chips (so the chips do not show) and roll it into a ball.
In a small bowl, mix sugar and cinnamon together. Roll each piece of dough in the cinnamon sugar mixture.
Place sugared dough into the muffin cups; 3-4 per cup.
If there are left over chocolate and peanut butter chips, feel free to add extras in and around the dough.
In a small saucepan, combine butter, peanut butter, brown sugar, 1 Tbsp milk (or cream), and vanilla extract. Once all ingredients are combined, bring to a boil. As soon as it's boiling, take it off the heat. If the sauce is too thick, add in the last Tbsp of milk (or cream).
*Spoon a little of the sauce over each muffin cup, repeating until you are out of sauce.
Bake for 12-15 minutes, or until biscuits are golden brown.
Best when served warm. Enjoy!
