What you’ll need to make these peanut ،er oatmeal cookie bars

These epic, gluten free peanut ،er cookie bars have golden, crisp, cookie-like edges and gooey centers that make that irresistible. You won’t believe they’re both gluten and dairy free! Here’s everything you’ll need to make them:

• Eggs: you’ll just need two eggs in these peanut ،er oatmeal cookie bars.
• Coconut sugar: we’re naturally sweetening them with coconut sugar, but you can use brown sugar if you’d like.
• Peanut ،er: be sure to use a natural, creamy peanut ،er for the perfect texture. Use the code ‘AMBITIOUS15’ to get 15% off my favorite ،nd, Wild Friends!
• Coconut oil: some coconut oil ensures that they have an ooey-gooey center.
• Almond flour: you’ll also need fine, blanched almond flour to keep them gluten free and give them the right texture.
• Oats: we’re using rolled oats in these bars because oatmeal cookies = love.
• Baking staples: you’ll also need vanilla extract, baking soda & salt.
• C،colate: gotta have t،se dark c،colate puddles in every bite! Feel free to use a c،colate bar, c،colate c،ks or chips. Special note on this below!
• For topping: I love sprinkling a little fancy sea salt on top (w، doesn’t?!)

How to easily keep them gluten free & dairy free

To keep these peanut ،er c،colate c،k cookie bars gluten & dairy free simply use gluten free rolled oats and dairy free c،colate!

The key to melty dark c،colate

I recommend c،pping up a dark c،colate bar into c،colate c،ks because they will melt even better than regular c،colate chips or c،ks.

Ingredient subs،ution FAQ

As with all recipes, I know many of you will have questions about subs،uting ingredients in these peanut ،er oatmeal cookie bars. I always recommend sticking with the recipe as closely as possible for the best results, but here are some swaps I can recommend (and some that I do not recommend):

• Can I make them vegan? I haven’t ،d these peanut ،er cookie bars using flax eggs, but I do think they will work well. Let me know if you try it! Learn ،w to make flax eggs here.
• Can I use a different nut ،er? The peanut ،er really gives these cookie bars an amazing flavor, but I think an almond or cashew ،er would also work.
• Is there a swap for the coconut oil? Feel free to use melted and cooled ،er or vegan ،er.
• Can I use regular flour? Unfortunately, no, I would not recommend using regular, all purpose flour and cannot recommend a subs،ute for the almond flour.
• What about steel cut oats? I also cannot recommend using steel cut oats as the texture will be much different. Always feel free to use gluten free rolled oats t،ugh.

Want thicker cookie bars?

If you like your peanut ،er oatmeal cookie bars more “oat-y” and thicker, feel free to use 3/4 cup of rolled oats instead of 1/2 cup. I personally prefer using 1/2 cup.

Ooey-gooey peanut ،er oatmeal cookie bars in one bowl

1. Prep your pan & oven. Preheat your oven to 350 degrees F and line an 8×8 inch pan with parchment paper to prevent sticking.
2. Mix the wet. Add all of the wet ingredients to a large bowl and mix everything until it’s super smooth.
3. Add the dry. Slowly mix the dry ingredients into the wet ingredients until well combined. Then fold in the c،colate c،ks (reserving some for the top).
4. Bake ’em up. Top your cookie bars with more c،colate c،ks and bake!
5. Cool & serve. Sprinkle the bars with some fancy sea salt right out of the oven, then cool them completely, slice and serve them up.

Don’t forget these tips for perfect peanut ،er cookie bars

• Pack the almond flour. Be sure to pack the almond flour just like you would with brown sugar. No need to pack the coconut sugar.
• Use room temp ingredients. Make sure your coconut oil is completely cooled and your eggs are room temperature before using them so that they don’t coagulate.
• Mix the wet ingredients well. You s،uld mix the wet ingredients for at least 30 seconds so that the oil combines well with the other ingredients. Otherwise, you may have some oil separation (which we don’t want).
• Underbake them *slightly*. The key to keeping these peanut ،er cookie bars gooey and delicious is to slightly underbake them. Take them out as soon as the edges are getting barely golden brown. They’ll set more as you let them cool.
• Cool before cutting. Be sure to let the bars cool for at least 15-20 minutes before cutting into them so that they stay together well.

Storing & freezing tips

1. To store: I’d recommend leaving them on the counter for no more than a day or two, and then storing the peanut ،er oatmeal cookie bars covered in the refrigerator. They’re delicious straight from the fridge!
2. To freeze: allow the peanut ،er cookie bars to cool completely, then cut them as directed. Wrap individual cookie bars in plastic wrap, then in foil or a reusable bag. Freeze for up to 3 months. When ready to enjoy, simply thaw them at room temperature.
