You don't have to have any specialty ingredients on hand to make a delicious gluten-free treat. These cookies taste just like their classic peanut butter cookie counterpart and they're made with three simple ingredients—peanut butter, eggs, and sugar.

Gluten-Free Cookie Ingredients

Though these ingredients are pretty straight forward, here's a few tips from the Test Kitchen to make sure your homemade cookies don't disappoint.

• Sugar: The recipe calls for granulated sugar but you can swap that out for brown sugar if you like. Brown sugar is made when sugarcane molasses is added to refined white sugar crystals. In this recipe sugar obviously adds sweetness but also makes the cookies crisp and brown as they bake.
• Peanut Butter: The good news about peanut butter is that the most popular brands of peanut butter sold on grocery store shelves is gluten free. Check the labels for certified gluten free language, but you should not have to shop for specialty peanut butter. If you prefer a natural peanut butter over the homogenized regular peanut butter, you can use it in this recipe, again, checking the label to ensure it is made in a gluten-free environment. Make sure to stir natural peanut butter to blend in the oil that has separated to the top before measuring it for this gluten free peanut butter cookie recipe.
• Eggs: The Test Kitchen tests recipes using large eggs which measure about 3 1/2 tablespoons per egg. If you need to substitute different size eggs, refer to this egg substitute guide for help. Since this recipe doesn't call for flour eggs are important for structure. Their protein helps to provide a framework that contributes to the texture of the cookies.
