Easiest Peanut Butter Cookie

I don’t know about you, but any cookie with only three ingredients is an automatic winner in my book. That’s why I love this recipe. It’s the perfect no-fail dessert that you literally can’t mess up, like my cake mix cookies.

Ladies and gentlemen get your milk glasses ready for dunking. These three ingredient peanut butter cookies will be done in less than 15 minutes from start to finish.They are easy to make, soft, chewy and full of flavor. They only take one bowl, a spoon and 3 ingredients to make: peanut butter, an egg and sugar. It doesn’t get easier than that!

These are a classic staple recipe to keep on hand for when you run out of flour or are looking for an easy cookie recipe to make. I bet you already have the ingredients on hand, too. Seriously, so simple and delicious!

And if you know me I love cookies. Some of my other favorites are my peanut butter cookies with chocolate chips, and no bake cookies.

3 Simple Ingredients!

• Peanut butter
• Sugar
• Egg

How to make Peanut Butter Cookies

MIX. Mix together the ingredients in a medium bowl. If the dough is too sticky, feel free to chill it in the fridge for 10 to 20 minutes.

ROLL. Use a medium cookie scoop or your hands to roll the dough into balls. You should end up with 12 (1″) balls. Then roll the dough ball into more granulated sugar and place on a lined baking sheet. Press down twice with a fork, creating a cross pattern.

BAKE. Bake in oven at 350°F for 8 to 10 minutes, or until the bottoms are very lightly browned.

Variations

• Don’t press the cookie with a fork and add a Hershey Kiss to the top instead. You can also add a Reese’s cup, like I did with these peanut butter cup cookies.
• Dip half the cookie in melted chocolate.
• Use brown sugar in place of granulated sugar.
• Use baking splenda if you want less sugar.
• Add a teaspoon of vanilla for even more flavor.

Helpful Tips

Chill the dough

If the dough feels too sticky to work with, try chilling it in the fridge for 10 to 20 minutes prior to scooping.

Press with a fork

Because there’s no flour or butter, these cookies don’t spread in the oven. After you roll the dough into balls, make sure to press down on them with a fork so that they flatten out. This helps them cook evenly and gives them a circular shape.

Don’t over bake

These cookies don’t need to cook that long…only 8 to 10 minutes. Once the edges and bottoms are lightly golden, remove them from the oven. They’ll continue to firm up once they’re removed from the oven and begin cooling.
