Ingredients for 1 egg peanut butter cookie
Ten simple ingredients for cookies that taste like peanut butter heaven.
| Ingredient | Amount | Notes |
|---|---|---|
| Creamy Peanut Butter 🥜 | 1 cup | Natural, unsweetened preferred |
| Large Egg 🥚 | 1 whole | Room temperature for best mixing |
| Granulated Sugar 🍚 | ½ cup | White or light brown sugar |
| All-Purpose Flour 🌾 | 1 cup | Spooning method for accurate measure |
| Baking Soda 🧂 | ½ tsp | Ensures proper rise |
| Vanilla Extract 🌿 | 1 tsp | Pure extract, not imitation |
| Sea Salt 🧂 | ½ tsp | Fine grain preferred |
| Unsalted Butter 🧈 | ¼ cup | Cold, cubed for texture |
| Chocolate Chips 🍫 | ½ cup | Semi-sweet or milk chocolate |
| Chopped Peanuts 🥜 | ¼ cup | Optional for extra crunch |
The peanut butter is non-negotiable here—natural, unsweetened gives the best flavor without extra sugar. Jif or Skippy work perfectly, but if you've got a fancy peanut butter like Smucker's Natural, go for it. The butter? Cold cubes create those beautiful flecks in the dough. I grab my butter from Trader Joe's because it's cheaper and never watery. Flour matters too—King Arthur or Gold Medal are my go-tos for consistent baking. Keep everything in the pantry until you're ready to mix.
No vanilla extract? Vanilla bean paste works too, just use half the amount. Short on chocolate chips? White chocolate or caramel bits add a fun twist. The peanuts are totally optional, but they add that extra crunch I can't resist. If you're making these for a crowd, double the batch—just bake them in two rounds. And trust me, don't skip the salt. It balances all that peanut butter sweetness perfectly.
Dough keeps for 3 days in the fridge, wrapped tight in plastic. For longer storage, freeze portions for up to 3 months. Baked cookies stay fresh for 5 days in an airtight container. Pro tip: store them in layers with parchment paper between each to keep them from sticking. These cookies reheat beautifully—just 10 seconds in the microwave brings back that fresh-out-of-the-oven warmth.

- No Mixer Needed: I swear by this recipe when I’m too tired to pull out the food processor. Just mash the peanut butter with the egg and sugar—no lumps, no fuss—then fold in the dry stuff. The dough’s thick but pliable, and those little cracks when they bake? Worth every second.
- One-Bowl Magic: Honestly, I’ve made this recipe on a camping trip with a cooler as my mixing station. Five ingredients, one bowl, and you’re done. The baking soda gives them just enough lift so they’re not flat, but still chewy enough to make you lick the pan.

- Penny-Pincher’s Dream: A single egg, a jar of peanut butter, and a bag of flour stretch this recipe into dozens. I’ve made three batches for under $5 total, and they disappear faster than my willpower when I’m craving something sweet. Budget-friendly doesn’t get better than this.
Step-by-step instructions for 1 egg peanut butter cookies
Here's how to make these rich, nutty cookies with minimal effort.
Cream the Peanut Butter and Butter Together
In a large mixing bowl, combine the 1 cup creamy peanut butter and 0.25 cup unsalted butter (cold, cubed). Use a hand mixer or stand mixer on medium speed for 3-4 minutes until smooth and fully blended. You're looking for a thick, creamy texture that nearly doubles in volume—this ensures your cookies stay tender and chewy.
I like to let the peanut butter and butter come to room temperature first (about 15 minutes out of the fridge) so they mix more easily. If your peanut butter is too thick, you can warm it slightly in the microwave for 10-15 seconds—just don't overdo it or it'll separate. The mixture should be smooth, not grainy, so keep mixing until it's completely homogeneous.
Add Wet Ingredients and Mix Well
To the peanut butter mixture, add the 1 whole large egg, 0.5 cup granulated sugar, 1 tsp vanilla extract, and 0.5 tsp sea salt. Mix on medium speed for another 2-3 minutes until everything is fully incorporated and the batter looks smooth and glossy. The sugar should dissolve completely, and the batter should be thick but spreadable.
Here's the thing—don't rush this step. The batter should coat the back of a spoon, but still hold its shape when you lift it. If it's too runny, add 1-2 tablespoons of all-purpose flour to thicken it up. The goal is a dough that's soft but not sticky, so it holds together when you scoop it. If it's too sticky, chill it for 10 minutes before proceeding.
Fold in Dry Ingredients and Mix Just Until Combined
In a separate bowl, whisk together the 1 cup all-purpose flour and 0.5 tsp baking soda. Gradually add this dry mixture to the wet ingredients, mixing on low speed just until combined. Be careful not to overmix—you should still see some flour streaks in the dough. Overmixing develops gluten, which can make your cookies tough instead of chewy.
Once the dry ingredients are incorporated, fold in the 0.5 cup chocolate chips and 0.25 cup chopped peanuts by hand using a spatula. Make sure they're evenly distributed throughout the dough. If you're using optional ingredients like white chocolate chips or crushed pretzels, now's the time to add them too. The dough should hold together when pressed but still be soft and pliable.
Chill the Dough for Perfect Cookies
Cover the mixing bowl with plastic wrap and refrigerate for at least 30 minutes (or up to 24 hours if you want to prep ahead). Chilling the dough is crucial—it prevents the cookies from spreading too much in the oven and helps develop even more flavor. The cold dough also means you'll get that classic peanut butter cookie texture with crispy edges and a soft, chewy center.
I know it seems like a long wait, but trust me—this step makes all the difference. If you're in a hurry, you can pop the dough in the freezer for 15-20 minutes instead. Just make sure it's firm enough to handle when you're ready to scoop. Once chilled, the dough should be easy to work with and hold its shape when you scoop portions.
Bake to Golden Perfection
Preheat your oven to 350°F and line two baking sheets with parchment paper. Using a cookie scoop or tablespoon, drop 1-tablespoon portions of dough onto the prepared sheets, spacing them about 2 inches apart—they'll spread as they bake. For a classic peanut butter cookie look, flatten each scoop slightly with your fingers.
Bake for 10-12 minutes until the edges are golden brown and the centers look just slightly underdone. They'll continue cooking on the hot baking sheet after you remove them from the oven, so don't overbake. You want them soft in the middle with crispy edges. Let them cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
These cookies are best enjoyed warm, straight from the oven, but they'll keep at room temperature for 3-4 days in an airtight container. If you can resist eating them all at once, that is.
Pro Tips For Making 1 Egg Peanut Butter Cookie
- Chill the Dough: Mixing peanut butter and sugar releases a ton of heat—your dough will be warm enough to bake immediately. Skip the fridge and let it sit for 10 minutes first, or your cookies will spread into flat pancakes instead of thick, chewy rounds.
- Use Room-Temp Egg: Cold eggs mix unevenly with peanut butter, leaving streaks and an inconsistent texture. Take the egg out of the fridge 10–15 minutes before cracking it—this ensures a smooth batter and even baking.
- Weigh the Flour: Scooping flour from the bag packs it too tightly, leading to dense cookies. Use a kitchen scale for 1 cup (125g) of flour—lightly spoon it in, then level off with a knife. This keeps the texture tender and crumbly, not gummy.
- Bake Until Golden: Peanut butter cookies often look underdone when they’re actually done. Pull them when the edges are golden and the centers still look slightly soft—they’ll firm up as they cool. Overbaking turns them dry and sad.
Serving suggestions for leftovers
Classic Milk Pairing
Warm whole milk is my go-to pairing—its creamy richness complements the peanut butter's nutty depth beautifully. Pour a glass of milk heated to 140°F (just below boiling) and watch how the cookies melt into it.
For extra indulgence, add a splash of vanilla syrup or a pinch of cinnamon to the milk. This combo feels like a nostalgic hug, especially when the cookies are still warm from the oven. 🥛
Iced Coffee Twist
Cold brew or iced coffee transforms these cookies into a perfect afternoon treat. The bold, slightly bitter notes of coffee cut through the sweetness of the peanut butter, creating a balanced flavor profile.
I like to add a scoop of vanilla ice cream to my iced coffee and dip the cookies in for a decadent dessert. For a caffeine-free version, try chilled hibiscus tea with a squeeze of lemon. ☕

Frequently asked questions
Can I make these cookies without an egg?
The egg is essential for binding these cookies since we're using peanut butter as the primary fat. For a vegan version, replace the egg with 1 tablespoon ground flaxseed + 3 tablespoons water (let it thicken for 5 minutes). The texture will be slightly denser, but still delicious. For gluten-free baking, use a 1:1 gluten-free flour blend and add 0.5 teaspoon xanthan gum to the dry ingredients.
Why does my dough keep sticking to my hands?
This happens when the dough is too warm or too wet. Chill the dough for 30 minutes first—this firms it up. If it's still sticky, add 1-2 tablespoons more flour gradually until it holds together. Avoid overmixing once you add flour, as this can make the cookies tough. Work quickly with cold hands or use a silicone spatula to handle the dough.
Can I use powdered peanut butter instead of creamy?
Powdered peanut butter works perfectly and actually makes these cookies lighter and crispier. Use 1 cup powdered peanut butter (like PB2) and reduce the sugar to 0.25 cup since powdered versions are sweeter. The texture will be more cake-like rather than chewy, but still delicious. This version is also lower in fat and calories while keeping all the peanut flavor!
How do I prevent my cookies from spreading too much?
Chilling the dough for at least 30 minutes is key—this helps them hold their shape. Also, use a cookie scoop and flatten the dough balls slightly before baking. Bake on the middle rack at 350°F for 10-12 minutes—they'll continue cooking after you remove them from the oven. For thicker cookies, scoop 1.5 tablespoons of dough instead of 1.
What's the best way to store these cookies?
Keep them fresh for 5 days in an airtight container at room temperature. For longer storage, freeze portions for up to 3 months—just thaw at room temperature for 1 hour before enjoying. To maintain crisp edges, store them in a single layer with parchment paper between each cookie. Reheat in the oven at 300°F for 3-5 minutes to restore that fresh-baked warmth!
