Ingredients
Instructions
Preheat oven to 350°F.
Line a 9×13 metal baking pan with aluminum foil, using metal binder clips to keep foil in place. Spray sides and bottom of pan generously with cooking spray. Set aside.
In a medium bowl, combine the flour, baking powder, baking soda, and salt. Set aside.
In the large bowl of an electric mixer fitted with the paddle attachment, beat the butter, peanut butter, brown sugar, and granulated sugar on medium-high speed until very well combined, about 2 minutes.
Scrape down the sides and bottom of the bowl. Add the eggs, vanilla, and milk, and beat until combined.
On low speed, gradually add the flour mixture and beat until just combined. The dough will be thick.
Add the peanut butter chips, M&Ms, and chocolate chips and mix until just combined. You may need to do this by hand with a spatula if your mixer isn’t strong enough.
Remove the dough to the prepared pan, pressing into the pan evenly.
Sprinkle with the reserved M&Ms and chocolate chips.

To halve the recipe, cut all of the ingredients in half and use an 8×8-inch light-colored metal pan, shaving a few minutes off the bake time.
I haven’t tested these cookie bars using almond butter, but a 1:1 ratio swap worked perfectly with my Peanut Butter Cookies, so feel free to experiment with nut butters!
You can also turn these into regular peanut butter/chocolate chip cookies. Use my Giant Reese’s Pieces Chocolate Chip Cookies recipe and swap out the Reese’s Pieces for a twist on peanut butter holiday cookies.

I reduced the butter by 30%, added 1/2 plus 1/8 tsp xanthan gum, and used her blend of 50% tapioca flour, 25% millet flour and 25% buckwheat flour. Because I am at high altitude I also increased the milk by 2 tsp.
These bars are delicious and easy to make. Very peanut butter-forward, obviously, but everyone I've shared them with has greatly enjoyed them.
I converted these to Gf using Katarina Cermelj’s rules. They turned out great!
