Peanut Butter Brittle Cookies: A Symphony of Sweet & Salty

The clatter of the food processor, the sweet aroma of peanut butter swirling in the air, the satisfying crack of peanut brittle – these are the sensory memories that flood back every time I bake these cookies. As a child, my grandmother always had a jar of homemade peanut brittle on her counter. It was her signature treat, and she’d let me sneak pieces as a “chef’s perk” while she baked. These Peanut Butter Brittle Cookies are a love letter to those moments, a perfect marriage of her crunchy candy and the soft, comforting texture of a peanut butter cookie. They’re guaranteed to disappear as quickly as you can bake them!

Recipe Overview

Prep Time: 25 minutes
Cook Time: 13-15 minutes
Total Time: 40 minutes
Yields: 22 cookies
Serves: 22
Dietary Type: Not Gluten-Free

Ingredients

3 cups all-purpose flour
4 ounces peanut brittle
1 teaspoon baking powder
1 1⁄4 teaspoons salt
1 cup unsalted butter, at room temperature (2 sticks)
1 cup creamy peanut butter
2 teaspoons vanilla extract
1 cup packed light brown sugar
1 cup granulated sugar, divided
2 large eggs

Equipment Needed

Food processor
Large mixing bowl
Medium mixing bowl
Baking sheets
Wire racks
3-inch round ramekin (or similar)

Instructions

Preheat your oven to 375°F (190°C).
In a medium bowl, combine the all-purpose flour, baking powder, and salt. Whisk or stir well to ensure the baking powder is evenly distributed; this helps achieve a consistent rise in the cookies. Set aside.
Now for the star of the show: the peanut brittle. Break it into smaller pieces and place it in a food processor. Pulse until the brittle is finely crushed. You should have approximately ¾ cup of crushed brittle. Add the crushed brittle to the bowl with the flour mixture and stir to combine.
In a large mixing bowl, cream together the unsalted butter and creamy peanut butter until smooth and well combined. Using room temperature butter is crucial for achieving a light and airy texture.
Add the packed light brown sugar and ½ cup of the granulated sugar to the butter and peanut butter mixture. Beat until the mixture is light in color and fluffy, about 2 minutes. This process incorporates air, resulting in a tender cookie. Make sure to scrape down the sides of the bowl periodically to ensure even mixing.
Add the vanilla extract and eggs to the bowl. Beat until smooth, scraping down the side of the bowl as needed.
Gradually add the flour mixture to the wet ingredients, beating on low speed until just combined. Be careful not to overmix the dough, as this can lead to tough cookies.
Place the remaining ½ cup of granulated sugar in a small bowl.
Roll ¼ cup of dough into a ball. Coat the dough ball in the granulated sugar, ensuring it is evenly covered.
Transfer the sugar-coated dough balls to ungreased baking sheets. Flatten each dough ball with a 3-inch round ramekin (or the bottom of a glass).
Use fork tines to make “+” marks on the surface of each cookie. This not only adds a decorative touch but also helps the cookies bake evenly.
Bake the cookies in the preheated 375°F (190°C) oven for 13-15 minutes, or until the edges are golden brown and the cookies are set. To ensure even baking, rotate the baking sheets halfway through the baking time. Keep a close eye on them, as ovens can vary.
Remove the baked cookies from the oven and transfer them to wire racks to cool completely.
Repeat with the remaining dough.
Store the cooled cookies at room temperature in an airtight container for up to 2 weeks.

Expert Tips & Tricks

Don’t skip the chilling step! If your dough is too soft, chilling it for 30 minutes to an hour will make it easier to handle and prevent the cookies from spreading too much in the oven.
Homemade peanut brittle is best, but store-bought works in a pinch. Just make sure it’s good quality and not too hard.
For a richer flavor, use dark brown sugar instead of light brown sugar.
If you want to get fancy, drizzle melted chocolate over the cooled cookies or sprinkle them with sea salt. The salt will enhance the sweet and salty flavors.
Underbaked cookies are better than overbaked! They’ll be softer and chewier.
To ensure a perfect bake, use an oven thermometer to verify your oven’s temperature.
Don’t overcrowd the baking sheet. Give the cookies enough space to spread without touching each other.

Serving & Storage Suggestions

These Peanut Butter Brittle Cookies are fantastic on their own, served alongside a cold glass of milk or a warm cup of coffee or tea. They also make a delightful addition to a dessert platter or as a homemade gift.

Store the cookies in an airtight container at room temperature for up to 2 weeks. They can also be frozen for longer storage. To freeze, place the cooled cookies in a single layer on a baking sheet and freeze until solid. Then, transfer them to a freezer bag or container. They will keep in the freezer for up to 3 months. Thaw at room temperature before serving.

Variations & Substitutions

Gluten-Free: Substitute a gluten-free all-purpose flour blend for the regular flour. Be sure to choose a blend that contains xanthan gum or another binding agent.
Vegan: Replace the butter with a vegan butter alternative, the eggs with flax eggs (1 tablespoon ground flaxseed mixed with 3 tablespoons water per egg), and ensure your peanut brittle is vegan-friendly (some contain dairy).
Different Nut Butter: Experiment with almond butter, cashew butter, or even sunflower seed butter for a unique twist on the flavor.
Chocolate Chips: Add chocolate chips to the dough for an extra dose of chocolatey goodness.
Spiced: Add a pinch of cinnamon or nutmeg to the dough for a warm, comforting flavor.
Peanut-Free: Use another type of brittle (sesame, for example) and sunflower seed butter for a peanut-free version.

FAQs (Frequently Asked Questions)

Q: My cookies are spreading too thin. What am I doing wrong?
A: The dough may be too warm. Try chilling it in the refrigerator for at least 30 minutes before baking. Also, make sure your oven temperature is accurate.

Q: Can I use crunchy peanut butter instead of creamy?
A: Yes, you can. It will add extra texture to the cookies.

Q: My peanut brittle is sticking to the food processor. What can I do?
A: Try pulsing the brittle in smaller batches. You can also add a tablespoon of flour to the food processor to help absorb any stickiness.

Q: How do I know when the cookies are done?
A: The edges should be golden brown and the centers should be set but still slightly soft. They will continue to firm up as they cool.

Q: Can I freeze the cookie dough?
A: Yes, you can freeze the cookie dough for up to 3 months. Roll the dough into balls, place them on a baking sheet, and freeze until solid. Then, transfer the frozen dough balls to a freezer bag or container. Bake from frozen, adding a few extra minutes to the baking time.
