- Gluten free flour blend - I tested this recipe using Bob's Red Mill 1 to 1 Gluten Free Flour Blend and King Arthur's Measure for Measure Gluten Free Blend. That doesn't mean others will not work, I just have not tested other flours.
- Xanthan gum - If your gluten free flour blend doesn’t contain xanthan gum or guar gum, please add 1 teaspoon.
- Almond flour - I highly suggest using almond flour and not almond meal. Almond meal is more coarse and will make your cookie bars grainy.
- Peanut butter - Use creamy unsalted or crunchy if you like more texture.
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.
Recipe step by step directions:
Step 1: Mix all of the dry ingredients in a bowl. (I use a whisk to make sure they are all blended together.)
I like to balance my gluten free baking with almond flour. I love this almond flour 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,
Step 2: Add all wet ingredients in a bowl and mix well. (I melt my butter so that it blends a lot easier.)
Step 3: Pour the wet ingredients into the dry ingredients. Add the mix-ins and mix well.
Step 4: Mix the cookie dough, spread it into an 8x8 pan, and bake. Bake at 350º F for 20-24 minutes until done.
To test for doneness, insert a toothpick into the center of the bars. If the toothpick comes out clean, it is done baking. If you see batter or crumbs, the cookie bars need to bake longer.

These cookie bars are so fun to make and so delicious! I knew they would be so good as I have made a wonderful couple of her recipes and they were delicious too.

Hey there. Can these be made grain free? These sound good!
Hi Becky, I haven't tested any grain-free ingredients in this recipe. I am inclined to say to try Cassava flour, but I am going with a guess so it may not work out.
