🧾3 Ingredient Peanut Butter Cookies Ingredients
Here’s the breakdown of what’s in this 3 Ingredient Peanut Butter Cookie recipe:
- Peanut Butter: I always use soft peanut butter because it mixes easily and gives the cookies a smooth, rich texture. It’s the heart of the recipe, bringing that deep, nutty flavor while also holding everything together since there’s no flour.
- White Sugar: This isn’t just for sweetness! It helps the cookies get that slightly crisp outside while keeping the inside nice and chewy. It also adds a little caramel-like flavor when it bakes, which makes the cookies even more delicious.
- Egg: I always use a room-temperature egg because it blends better with peanut butter and sugar. The egg is what keeps the cookies from falling apart, giving them structure and a soft, melt-in-your-mouth texture.

👩🏻🍳How to Make 3 Ingredient Peanut Butter Cookies
These step-by-step instructions and photos will help you to visualize how to make this recipe. See the recipe card for a printable version of this recipe.
1. Mix peanut butter, sugar, and egg in a bowl until a thick dough forms.
2. Scoop 1.5-tablespoon (35g) dough portions, roll into balls, and place on the baking tray.
3. Press each cookie with a fork in a crisscross pattern to shape your 3 Ingredient Peanut Butter Cookies.
4. Bake in a preheated oven at 175°C (350°F) or 155°C (fan) for 10–12 minutes until the edges are firm.
💭Tips for Recipe Success
Use a Room Temperature Egg: A room-temperature egg mixes in better, helping the dough come together smoothly for a softer, fluffier cookie.
Don’t Overmix: Mix the ingredients just enough to combine them. Overmixing can make the cookies dense instead of light and chewy.
Space the Cookies Out: Don’t crowd the cookies on the baking tray. Give them space to spread a bit as they bake.
Watch the Baking Time: These cookies bake quickly! Keep an eye on them and take them out as soon as the edges are golden. They’ll firm up as they cool, so don’t worry if they seem soft at first.
Storage: Store 3 Ingredient Peanut Butter Cookies in an airtight container at room temperature for up to one week, or freeze them for longer storage.
