These flourless peanut butter cookies are soft, chewy, and dangerously easy to make. Three ingredients, one bowl, zero fuss — and honestly? They’re better than most cookies I’ve baked from scratch.
I started making these on busy weeknights when the kids wanted something sweet and I had exactly zero energy to pull out the mixer. One jar of peanut butter, one egg, one cup of sugar — that’s it. I wasn’t expecting much. But the first batch came out of the oven smelling incredible, and now it’s one of those recipes I keep going back to.
If you’ve never made 3 ingredient peanut butter cookies before, you’re going to be a little shocked by how good they are. They’re naturally gluten free, chewy in the middle, slightly crispy on the edges, and they taste like actual peanut butter — not like a sad diet snack. My daughter asked me to bring these to her class, which honestly says everything.

Step-by-Step Instructions
-
1Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.
-
2Mix everything together. In a medium bowl, combine the peanut butter, sugar, and egg. Stir until a soft, slightly sticky dough forms — about a minute by hand.💡 A room temperature egg blends in more smoothly than a cold one. Take it out of the fridge 15 minutes before you start.
-
3Roll into balls. Scoop about 1 tablespoon of dough and roll into a ball. Place them on the prepared baking sheet about 2 inches apart.💡 If the dough feels too sticky to roll, chill it in the fridge for 15 minutes first — it firms up and becomes much easier to handle.
-
4Press with a fork. Use a fork to gently press a crosshatch pattern into each ball, flattening slightly. This gives them that classic peanut butter cookie look.💡 Sprinkle a tiny pinch of flaky sea salt over the top right before baking — it takes the flavor up a notch.
-
5Bake for 10–12 minutes. They’ll look slightly underdone when they come out — that’s perfect. They firm up as they cool.⚠️ Don’t overbake. Pull them out when the edges are just set and the centers still look soft. Overbaked peanut butter cookies go dry and crumbly fast.
-
6Cool before touching. Let them rest on the pan for at least 5 minutes, then transfer to a wire rack. They’re fragile while hot — trust the process.⚠️ These cookies are genuinely fragile when warm. Don’t try to move them early or they’ll crack. Five minutes on the tray makes all the difference.
3 Ingredient Peanut Butter Cookies That Actually Work (No Flour Needed)
🧄 Ingredients
- 1 ¾ cup creamy peanut butter
- 1 ¾ cup granulated white sugar
- 1 ¾ large egg
📋 Instructions
-
1
Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.
💡 Make sure the oven is fully preheated before baking for even results. -
2
In a medium bowl, combine the peanut butter, sugar, and egg. Stir until a soft, slightly sticky dough forms.
💡 Mix until fully combined — no dry sugar should remain at the bottom of the bowl. -
3
Scoop about 1 tablespoon of dough and roll into a ball. Place on the prepared baking sheet about 2 inches apart.
💡 If the dough feels too sticky, refrigerate for 15 minutes before rolling. -
4
Use a fork to gently press a crosshatch pattern into each ball, flattening to about half an inch thick.
💡 Lightly dip the fork in sugar between presses to prevent sticking. -
5
Bake for 10 to 12 minutes, until the edges are just set. The centers will look slightly underdone — that\'s correct.
💡 Do not overbake. They firm up as they cool and become perfectly chewy. -
6
Remove from the oven and let the cookies rest on the pan for 5 minutes, then transfer to a wire rack to cool completely.
💡 These cookies are fragile while warm. Do not move them too soon or they will crumble.

💡 Pro Tips
- Don’t overbake them. Pull them out when the edges are just set. They’ll look soft but they firm up into the perfect chewy texture as they cool.
- Room temperature egg works best — it helps everything bind smoothly and evenly.
- Use creamy PB for the smoothest texture. Chunky works but the cookies spread a little differently.
- Brown sugar instead of white gives you a slightly richer, almost caramel-like flavor — really good.
- Chill the dough for 15 minutes if it feels too sticky to roll. Makes shaping so much easier.
- Sprinkle a tiny bit of sea salt on top before baking — it takes the flavor up a notch.
Variations to Try
Fold in ½ cup of chocolate chips to the dough, or press a few on top right before baking. Peanut butter and chocolate — you genuinely can’t go wrong.
Bake as usual, cool completely, then dip the bottom half in melted dark chocolate. Set on parchment until firm. They look beautiful and taste even better.
Swap peanut butter for almond butter for a slightly lighter, nuttier flavor. Same quantities, same method. Great if someone has a peanut allergy.
Add ½ tsp cinnamon to the dough and roll the balls in cinnamon sugar before baking. Warm, cozy, and a little different from the classic.
Serving Ideas
- Serve warm with a glass of cold milk — classic for a reason
- Crumble over vanilla ice cream for an easy no-fuss dessert
- Pair with hot coffee or chai tea for a cozy afternoon snack
- Wrap in cellophane bags tied with ribbon — they make really sweet homemade gifts
- Pack in lunchboxes — they hold up well and kids absolutely love them
Storage & Reheating
| Where | How long | Notes |
|---|---|---|
| 🌡️ Room temp | Up to 5 days | Airtight container — actually get chewier on day 2, which I think makes them better |
| ❄️ Fridge | Up to 2 weeks | Sealed container — let them come to room temp before eating or they’ll be a little dense |
| 🧊 Freezer | Up to 3 months | Layer between parchment paper — thaw on the counter for 30 minutes before serving |
| 🔥 Reheat | 10 seconds | Microwave brings back that fresh-baked warmth — don’t overdo it or they dry out |
