Ingredients
For the best flavor, use creamy peanut butter, but chunky works too if you like a little crunch!
-
- 1 cup creamy peanut butter
-
- 1 cup granulated sugar
-
- 1 large egg

Tip: For just 2 people, use ½ cup of each ingredient. If you want to make more than 4 servings, simply double the recipe.
Instructions
Step 1: Preparation
Start by preheating your oven to 350°F (175°C). Grab a cookie sheet and line it with parchment paper so your cookies won’t stick.
Step 2: Main Cooking Process
In a large bowl, combine the peanut butter, sugar, and egg. Mix well until all the ingredients come together, and you have a smooth batter with a rich aroma of peanut butter.
Step 3: Combining Ingredients
Using a spoon or your hands, scoop out small balls of dough and place them on the prepared cookie sheet, leaving a bit of space between each one. The dough should feel soft but not too sticky.
Step 4: Finishing & Final Simmer
Flatten the balls with a fork to create that classic crisscross pattern. Bake in the preheated oven for about 10 minutes, watching until they start to turn golden at the edges but remain soft in the middle.
Why This Recipe Works for Busy Days
Are you pressed for time but still want homemade goodness? This recipe takes just about 20 minutes from start to finish, making it a lifesaver on busy days. Plus, since they’re so easy to make, leftovers (if there are any) can easily be packed for lunch or enjoyed as a late-night snack. Just pop them in the fridge, and you’re good to go!
Tips & Tricks
-
Watch the Bake Time: Overbaking can lead to dry cookies, so keep an eye on them! They’ll continue to firm up after coming out of the oven.
-
Sticking Together: If your dough is too sticky, chilling it in the fridge for a few minutes can make it easier to handle.
-
Batch Cooking: If you’re cooking for fewer than 4 people, save some dough for later! Unbaked dough can be frozen for future cravings.
-
Customize Your Cookies: Feel free to mix in chocolate chips or nuts for an extra flavor punch, just keep the main ingredient ratios the same.
Variations
-
Chocolate Chip Bliss: Stir in ½ cup of chocolate chips before baking for a sweet twist. They can elevate the cookies to a new level of deliciousness!
-
Nutty Delight: Use almond or cashew butter instead of peanut butter for a different nutty profile. These variations cater to different tastes and allergies.
-
Sugar Swap: If you want a healthier option, use coconut sugar instead of granulated sugar for a lovely caramel flavor and a more natural sweetener.
-
Flavored Boost: Add a teaspoon of vanilla extract or a sprinkle of sea salt on top before baking for an extra flavor layer.
