The Easiest 3 Ingredient Peanut Butter Cookies You'll Ever Make

What makes them special is how reliable they are. The edges set gently, the centers stay soft, and the peanut butter flavor really stands out. They're simple, quick, and exactly what you expect from 3-ingredient chewy peanut butter cookies.

Ingredients in 3 Ingredient Peanut Butter Cookies
Here's the breakdown of what's in this 3 Ingredient Peanut Butter Cookie recipe:
- Peanut Butter: I use creamy, shelf-stable peanut butter because it blends smoothly and keeps the texture soft and cohesive.
- White Sugar & Egg: The sugar gives structure and a light, crisp edge, while the egg binds everything together and creates that chewy center.
How to Make 3 Ingredient Peanut Butter Cookies
You can find the complete printable recipe with measurements below, but for now, here's a quick overview of how it goes:
1. Make the Dough: Mix peanut butter, sugar, and egg in a bowl until a thick dough forms.
2. Shape the Cookies: Scoop 1.5 tablespoons (35g) of dough portions, roll into balls, and place on the baking tray.
3. Press the Pattern: Press each cookie with a fork in a crisscross pattern to shape your 3 Ingredient Peanut Butter Cookies.
4. Bake: Bake in a preheated oven at 350°F /175°C (310°F convection / 155°C fan) for 10-12 minutes until the edges are firm.
My Tips for Recipe Success
Use Classic Peanut Butter: I always go for shelf-stable peanut butter; natural versions can be too oily or dry for this dough.
Use a Room Temperature Egg: I take the egg out a bit earlier so it mixes more easily with the peanut butter and sugar. It helps the dough come together more smoothly.
Let them Rest Before Moving: The cookies come out soft; letting them sit helps them firm up and stay together.
Storage
I keep leftovers in an airtight container at room temperature. They stay soft for days and don't dry out.
