These gluten free peanut butter bars are moist and chewy, and all things yummy. My kids devoured the first batch I made. That shouldn’t surprise you at all. That is how we roll in our house. If it doesn’t have a DON’T EAT ME sign on it, it is fair game.

Post Its are commonly seen on food both in the pantry, and in our refrigerator :-). This is the best peanut butter cookie recipe I have made and in order to make more, I have to make sure nobody eats all of the peanut butter!

For my recipe, I used M&Ms. Feel free to use dark chocolate chips, milk chocolate chips, or even bittersweet chocolate chunks. The sky is the limit as long as it is chocolate… because you know chocolate is just amazing with peanut butter.

Check out my quick video on how to make these gluten free peanut butter cookies.


To summarize the easy steps to make these homemade peanut butter cookie bars:

  1. Mix all of the dry ingredients in a bowl. (I use a whisk to make sure they are all blended together.)
  2. Add all wet ingredients in a bowl and mix well. (I melt my butter so that it blends a lot easier.)
  3. Pour the wet ingredients into the dry ingredients.
  4. Add chocolate, lots of it.
  5. Mix the cookie dough, spread into an 8×8 pan, and bake.

I love when it is that easy!!

Peanut Butter

I used peanut butter to make these cookies. You can use Sun Butter if you are allergic to peanuts. I used a regular peanut butter. You can use natural peanut butter, or even almond butter. You will find these cookie bars are very easy to customize in many different ways.

Almond Flour

I like to balance my gluten free baking with almond flour. I love this brand because it is so finely ground. (Adding a bit of protein also helps to balance out the sugar in this recipe. If you can’t use almond flour, you can add 1/4 cup additional gluten free flour to the recipe.

And here they are ready to eat :-).
