3 Ingredient Peanut Butter Cookie with Sea Salt

3 Ingredient Peanut Butter Cookie Basics

The smell of toasted peanuts and caramelized sugar hitting the oven air is enough to bring anyone into the kitchen. I remember trying a version of this years ago where I used "natural" peanut butter that had separated. The result was a total disaster, a huge, oily puddle that covered my entire baking sheet.

It looked more like a peanut butter pancake than a cookie.

This is the only 3 Ingredient Peanut Butter Cookie with Sea Salt recipe you'll ever need. The fix for the "puddle problem" is simple: stick to stabilized peanut butter and don't skimp on the mixing time.

Making a 3 Ingredient Peanut Butter Cookie is easier than you'd think, and it avoids that rubbery texture some flourless bakes get. You can expect a cookie that has a slight crackle on top and a soft, melt in-your mouth center.

The Logic Behind the Texture

• The Egg Binder: Since there is no flour, the egg proteins act as the glue. They stop the fats from just melting away.
• Sugar Structure: The sugar doesn't just sweeten. It crystallizes during the bake, which gives the cookie its shape and a slight crispness.
• Fat Ratio: Peanut butter provides the necessary fat for a rich mouthfeel without needing to cream butter.

The Essential Kitchen Tools

This recipe requires very few tools. A medium mixing bowl and a handheld electric mixer, like a cordless KitchenAid, are all you need for the prep. You will also need a large baking sheet and some parchment paper.

Don't skip the parchment paper. The high sugar content causes these cookies to cling to metal pans, and you'll end up tearing them apart without a liner. To get the traditional crosshatch look, all you need is a basic fork.

Ingredients and Simple Swaps

• 1 cup (250g) creamy peanut butter Why this? Supplies the necessary fat and body.
• 1 cup (200g) granulated white sugar Why this? Ensures the edges get crisp.
• 1 large (50g) egg, room temperature Why this? Acts as the primary binder.
• 1/2 tsp (3g) flaky sea salt Why this? Balances the heavy sweetness.

Cooking Time and Temp

Right then, here are the numbers you need to keep the bake on track.

Precision Checkpoints:

• Oven Temp: 350°F (175°C)
• Ball Size: 1 inch diameter
• Bake Time: 8-10 minutes

Fast vs. Classic Comparison

Step by step Baking

1. Set your oven to 350°F (175°C). Cover a large baking tray with parchment paper to ensure the cookies release easily.
2. Add the peanut butter, sugar, and egg to a mixing bowl.
3. Mix on medium speed for 2-3 minutes. Note: Continue beating until the dough looks smooth, glossy, and velvety.
4. Take 1 tablespoon of dough and roll it between your palms into a 1 inch ball.
5. Arrange the balls on the tray, spacing them 2 inches apart to allow for expansion.
6. Use a fork to press a crosshatch design into the top, flattening them slightly.
7. Immediately top each cookie with a tiny pinch of flaky sea salt.
8. Bake for 8-10 minutes until the edges are a light golden brown.
9. Leave them on the pan for 5 minutes. Note: They are quite soft when first removed and need a moment to firm up.
10. Transfer them to a wire rack to cool completely.

Fixing Common Texture Issues

If your 3 Ingredient Peanut Butter Cookie is too flat, it usually comes down to the peanut butter. Natural brands that have oil sitting at the top tend to spread more. To fix this, stir your peanut butter thoroughly before measuring or chill the dough for 30 minutes before scooping.

When the cookies come out too dry or crumbly, it's often because they stayed in the oven for an extra minute. These bake fast, so pull them out while the centers still look a bit soft.

Cookies are too flat

This happens when the fat is too warm or the peanut butter is too oily. Use a stabilized brand and avoid over mixing after the sugar is incorporated.

Edges are burnt

Your oven might be running hot. Lower the temp by 10 degrees or move the rack to the center position.

Texture is grainy

This means the sugar didn't fully integrate. Beat the dough for another 60 seconds until it looks glossy.

Storage and Freezer Tips

Keep these in a tightly closed jar in the fridge for around 7 days to maintain their rich, fudgy texture. For longer storage, they freeze wonderfully.

Place the baked treats on a tray in the freezer for one hour before transferring them to a freezer bag. They'll last for 3 months. To enjoy, simply let them sit at room temperature for 20 minutes or microwave them for 10 seconds.

Since the process is so simple, there's hardly any waste. If you have a bit of leftover dough in the bowl, just scrape it all out to make yourself a "monster cookie."

Flavor Tweaks and Variations

If you're feeling bold, try using chunky peanut butter for a bit of a crunch. You can also swap the white sugar for brown sugar to get a deeper, molasses like flavor.

For those who love nuts in everything, you might enjoy a savory contrast with something like Skinny Thai Chicken Meatballs for dinner before diving into these desserts.

Decision Shortcut

The Best Way to Serve

While delicious on their own, these treats really stand out on a dessert platter. I suggest pairing them with a bold cup of coffee or a cold glass of milk to balance the richness.

If you're arranging a spread for guests, these pair perfectly with Chocolate Covered Strawberries for a great variety of textures.

Just be careful not to overbake them. The secret to these addictive 3 Ingredient Peanut Butter Cookies is that slightly soft, underdone center. They are best enjoyed while still warm from the oven.
