Step 1

Preheat oven to 350º F and lightly grease a 9×13-inch baking dish with butter or non-stick spray.

Combine flour, baking soda and salt in a medium bowl and set aside.

In a large bowl or mixer, cream together brown sugar, peanut butter and butter until fluffy and lightened in color. 3-5 minutes.

Beat in egg and then, once fully incorporated, milk and vanilla extract.

Stir in dry ingredients, then gently fold in peanut butter chips.

Pour batter into greased baking dish, then smooth over the top and place in oven.

Bake for 18-21 minutes, or until top is golden brown and toothpick inserted in center comes out mostly clean.

Remove from oven and let cool 10 minutes before serving.
