Peanut Butter Chocolate Chip Cookie Bars

In another bowl, mix the softened butter and peanut butter until smooth.

Gradually add the granulated sugar and brown sugar, mixing until the texture becomes light and fluffy.

Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.

Slowly blend the dry ingredients into the wet ingredients until just combined.

Gently fold the peanut butter chips and semi-sweet chocolate chips into the dough.

Spread the dough evenly into the prepared baking pan.

Bake for 25-30 minutes, or until the edges are golden, and a toothpick inserted in the center comes out mostly clean.

Let the bars cool completely in the pan. Lift them out using the parchment paper and cut into squares.
