How to Make 3 Ingredient Peanut Butter Cookies

Step 1: Preheat the Oven

Preheat your oven to 350 degrees F. Line a large baking sheet with parchment paper or a Silpat baking mat. Set it aside for later.

Step 2: Mix Ingredients

In a large bowl, combine creamy peanut butter, granulated sugar, and large egg. You can use an electric mixer or a spatula. Mix until the mixture is creamy and smooth.

Step 3: Shape the Cookies

Scoop the cookie dough into balls, each about 1 tablespoon in size. Place them on your prepared baking sheet. Flatten each ball using the back of a fork to create a criss-cross pattern. Remember that these cookies don’t spread much during baking, so you can place them close together.

Step 4: Bake

Bake in the preheated oven for 8 to 10 minutes or until the edges are slightly golden. Be careful not to overbake! Once done, remove them from the oven and let them cool on the baking sheet for about 3 minutes before transferring them to a cooling rack to cool completely.

How to Perfect 3 Ingredient Peanut Butter Cookies

To ensure your 3 Ingredient Peanut Butter Cookies come out perfectly every time, consider these helpful tips.

Use creamy peanut butter: Creamy peanut butter gives the best texture and flavor. Avoid crunchy varieties for this recipe.
Measure accurately: Make sure you measure the ingredients correctly for the right balance. A kitchen scale can help.
Don’t overmix: Mix just until combined to keep your cookies soft and chewy. Overmixing can lead to tough cookies.
Chill the dough: If you have time, refrigerate the dough for about 30 minutes before baking. This helps the flavors develop and improves texture.
Watch the baking time: Keep an eye on your cookies while they bake. They should be just golden around the edges but still soft in the center when you remove them from the oven.
Cool properly: Allow the cookies to cool on the baking sheet before transferring them to a cooling rack. This helps them set without breaking apart.

Best Side Dishes for 3 Ingredient Peanut Butter Cookies

While these cookies are delightful on their own, pairing them with certain side dishes can enhance your dessert experience even more.

Fresh Fruit Salad: A mix of seasonal fruits adds freshness and balances out the sweetness of the cookies.
Cheese Platter: Include some sharp cheeses that contrast nicely with the sweet peanut butter flavor; add nuts for crunch!
Yogurt Parfait: Layer yogurt with granola and berries for a refreshing complement that’s both healthy and delicious.
Chocolate Fondue: Set up a fondue station where guests can dip cookie pieces into melted chocolate for an interactive dessert experience.
Coffee or Tea: A warm cup of coffee or herbal tea pairs wonderfully with these cookies, enhancing their nutty flavors.
Nut Mix: Offer a bowl of mixed nuts as a crunchy side that complements the creamy texture of the peanut butter cookies.
Homemade Ice Cream Sundae Bar: Allow guests to create their own sundaes using ice cream, toppings, and crumbled cookie pieces for added fun!

Common Mistakes to Avoid

Overbaking the cookies: Keeping an eye on baking time is crucial. Remove them when the edges are slightly golden to keep them chewy.
Skipping the cooling time: Allowing cookies to cool on the baking sheet helps them set properly. Don’t rush this step!
