Peanut Butter Filled Chocolate Muffins

Step 1

Preheat oven to 350F and line 18 muffin cups with cupcake liners (or lightly grease and flour).

Step 2

Prepare Peanut Butter Filling first by microwaving cream cheese and peanut butter at 10 second intervals until it is easily stirred and combine.

Step 3

Stir in granulated sugar, egg, and vanilla. Set aside.

Step 4

In large bowl, whisk together oil, sugar, and milk. Stir in eggs and vanilla until well-combined.

Step 5

Gently fold in sour cream until just-combined.

Step 6

In separate, medium-sized bowl, whisk together flour, cocoa powder, baking soda, and salt.

Step 7

Fold flour mixture gently into wet mixture, folding until just barely combined. Stir in 1 1/2 cup chocolate chips.

Step 8

Scoop chocolate muffin batter into prepared muffin tin, filling only 1/2 full.

Step 9

Scoop heaping spoonfuls (I used a heaping 1 1/2" cookie dough scoop) peanut butter mixture on top of the chocolate batter, then cover with a layer of chocolate batter so that muffin cup is filled 2/3 TO 3/4 of the way full.

Step 10

Repeat until all batter has been dispersed.

Step 11

Sprinkle tops of muffins with remaining chocolate chips.

Step 12

Bake on 350F for 22-25 minutes (toothpick inserted in center should come out mostly clean, with a few crumbs.
