Amazing Peanut Butter Cup Biscotti

Step 1
Preheat oven to 350 degrees F (175 degrees C).

Step 2
Line 2 baking sheets with parchment paper.

Step 3
Mix the milk and vanilla extract together in a small bowl; set aside.

Step 4
Combine the flour and baking powder in a separate bowl.

Step 5
Beat the peanut butter, brown sugar, and white sugar with an electric mixer in a large bowl until smooth.

Step 6
Add the eggs one at a time, allowing each egg to blend into the peanut butter mixture before adding the next.

Step 7
Pour in the flour mixture alternately with the milk, mixing until just incorporated.

Step 8
Fold in the peanut butter chips; mixing just enough to evenly combine.

Step 9
Divide the dough into 4 equal parts.

Step 10
Roll each section into a 4×5-inch rectangle about 1/2-inch thick.

Step 11
Transfer the dough pieces onto the prepared baking sheets.

Step 12
Bake in the preheated oven until firm to the touch, about 25 minutes.

Step 13
Place biscotti loaves on wire racks to cool.

Step 14
Reduce oven temperature to 300 degrees F (150 degrees C).

Step 15
Cut each loaf into 1/2-inch slices.

Step 16
Return the slices to the baking sheets with the cut sides up.

Step 17
Bake in the oven until biscotti are dry, about 10 minutes on each side.

Step 18
Cool in the pans for 10 minutes before removing to cool completely on a wire rack.

Step 19
Melt the chocolate chips in a microwave-safe glass or ceramic bowl in 30-second intervals, stirring after each interval, until melted and smooth, 1 to 3 minutes (depending on your microwave).

Step 20
Dip the cooled biscotti into the melted chocolate. Set the biscotti onto parchment paper, and allow to set, about 20 minutes.
