Ingredients

• 1 cup (240 g) creamy peanut butter (natural or regular)
• 1 cup (200 g) granulated sugar (or 3/4 cup brown sugar for a deeper flavor)
• 1 large egg, at room temperature
• 1 teaspoon baking soda
• 1 teaspoon vanilla extract
• Pinch of salt (if your peanut butter is unsalted, add 1/4 teaspoon)

Notes:

• Use smooth peanut butter for an even texture. If your peanut butter separates, stir it first.
• Let the egg sit at room temp for about 10 minutes so it mixes easily.

How to Make The Best Flourless Peanut Butter Cookies:

1. Preheat the oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone mat. (Preheating ensures even rise and a nicely browned edge.)
2. In a medium bowl, stir the peanut butter and sugar until smooth. Use a spatula or wooden spoon.

• Mini-tip: scrape the bowl sides so sugar blends well with peanut butter for even sweetness.

1. Add the egg and vanilla. Mix until fully combined and slightly glossy.

• Why this matters: the egg binds and gives the cookie a tender center.

1. Sprinkle in the baking soda and the pinch of salt. Fold until the dough comes together.

• Mini-tip: don’t overmix; stop when you no longer see streaks. Overworking can make cookies tough.

1. Scoop tablespoon-sized portions and roll into balls. Place them 2 inches apart on the baking sheet.

• Tip: wet your hands lightly if dough sticks.

1. Use a fork to press each ball into a crisscross pattern, flattening to about 1/2 inch thick.

• Why: this helps them bake evenly and gives the classic peanut butter look.

1. Bake for 10–12 minutes, until the edges are lightly golden and you smell the roasted peanuts. The centers will look a touch soft — they firm as they cool.

• Mini-tip: for chewier centers, bake closer to 10 minutes; for crisper cookies, bake a minute or two longer.

1. Let the cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.

How to Serve The Best Flourless Peanut Butter Cookies

• Arrange warm on a small plate with a glass of cold milk or a mug of hot tea for cozy snacking.
• Stack them on a serving board with a few chocolate chips or sea salt flakes on top for a simple garnish.
• Pack in a lunchbox with a note — they travel well and keep their shape.

How to Store The Best Flourless Peanut Butter Cookies

• At room temperature: keep in an airtight container for up to 4 days. Place a sheet of parchment between layers.
• In the fridge: store up to 2 weeks in an airtight container; bring to room temp before serving for best texture.
• In the freezer: freeze baked cookies in a single layer on a tray, then move to a freezer bag for up to 3 months. Thaw at room temperature or warm gently in a low oven (300°F/150°C) for 5–7 minutes.

Tips to Make The Best Flourless Peanut Butter Cookies

• Use room-temperature egg for smooth mixing.
• Don’t skip the baking soda — it lightens the cookie and keeps the center tender.
• Press with a fork right before baking to keep a neat pattern.
• Swap half the sugar for brown sugar for a chewier, more caramel flavor.

Variation (if any)

• Chocolate chip twist: fold in 1/2 cup mini chocolate chips into the dough for little pockets of melted chocolate.
• Nut-free version: use sunflower seed butter instead of peanut butter for a safe, allergy-friendly cookie.

FAQs

Can I use crunchy peanut butter instead of smooth?

Yes. Crunchy peanut butter adds texture and little nutty bites. Mix a bit more gently so the chunks stay in the dough.

Do I need to chill the dough?

No, these cookies bake well right away. Chilling can firm the dough and slightly slow spreading, which can help if your kitchen is very warm.

Can I make these without an egg?

You can try a flax egg (1 tablespoon ground flax + 3 tablespoons water, chilled 5 minutes), but the texture will be slightly denser and less tender than with a real egg.

Why did my cookies spread too much?

If your cookies spread too much, your peanut butter may be very oily or your oven temperature too low. Chill the dough for 15 minutes and double-check the oven temp with an oven thermometer.
