Flourless Peanut Butter Cookies: Ingredients & Substitutions 

These gluten-free peanut butter cookies are made with ingredients you probably have on hand! Let's chat about possible substitutions. 

• Creamy peanut butter. choose your favorite peanut butter variety! Allergic to peanuts? Any nut or seed butter should work well in this recipe! I recommend using a peanut butter that is solid at room temperature. Some natural varieties do meet this requirement and can be used. If you use a peanut butter that's liquid at room temperature (like this homemade peanut butter), you will have to chill the dough for 60 minutes before baking.
• Sugar. Use granulated sugar or organic cane sugar for the best results. Note. I tired coconut sugar and it did not work. 
• Chocolate. Drizzling chocolate on top of these cookies, or adding chocolate chips to the batter, is optional, but delicious! 

How to make Flourless Peanut Butter Cookies

These gluten-free peanut butter cookies are made in one bowl and 15 minutes (from start to finish)! Let's walk through the process together, and don't forget to watch the video!

Combine Peanut Butter and Sugar

The first step in this flourless peanut butter cookie recipe is to combine the peanut butter and sugar. You can do this either by hand, with a hand-held mixer, or in a standing mixer. It's completely up to you. 

You may need to warm the peanut butter. If your peanut butter is too hard to serve (if you store it in the fridge or use a more solid variety), gently warm it in the microwave until it's soft enough to stir. Be careful not to overhead or you run the risk of cooking the egg when it's added to the batter.

Add the egg, vanilla and sea salt

Next, add the rest of the ingredients and beat or stir until everything is combined. 

Measure and roll out dough

I recommend using a 1 TBS measuring spoon or cookie scoop to make these flourless peanut butter cookies. Measuring out the dough ensures that every cookie is the same size, which means they will all bake evenly.

Make a criss cross pattern on top

Line a baking sheet with parchment paper and place the dough balls on top.  Use a fork to make a criss cross pattern on the top of each peanut butter cookie, gently pressing it down.

Bake

Note: Do NOT over bake! These flourless peanut butter cookies may not look completely done when you remove them from the oven. But they will cook more as they cool on the pan before being transferred to a wire rack.

So please don't bake them longer than 10 minutes if you can help it (although be aware that all ovens are different and you need to know how warm/cool/normal yours bakes).

Cool 

Once the cookies are removed from the oven, let them cool on the baking pan for at least 10 minutes before transferring them to a wire rack to cool completely. 

Dip in Chocolate

If desired, wait until the gluten-free peanut butter cookies are completely cool, then dip them in chocolate. To do this:

1. Melt some chocolate chips or chopped chocolate in the microwave or in a double boiler over medium heat. 
2. Line a large baking sheet with wax paper. 
3. Dip half of each cookie into the melted chocolate, then place on the wax paper. 
4. Let harden at room temperature or in the freezer. 
5. If desired, drizzle a little extra chocolate over the dipped side for a pretty texture. 
6. Enjoy!

Store/freeze

Store in an airtight container at room temperature for up to 5 days or in the freezer for up to 2 months. If you add chocolate on top, be sure to let it harden completely before stacking them in a container.
