Ingredients: What You’ll Need
To achieve the best results, using high-quality ingredients is key. Here’s what you’ll need for both the brownie and peanut butter cookie doughs.
For the Brownie Dough
- 1/2 cup (1 stick) unsalted butter, melted
- 1 cup granulated sugar
- 1 large egg
- 1 teaspoon vanilla extract
- 1/3 cup unsweetened cocoa powder
- 1/2 cup all-purpose flour
- 1/4 teaspoon salt
- 1/4 teaspoon baking powder
For the Peanut Butter Cookie Dough
- 1/2 cup (1 stick) unsalted butter, softened
- 1/2 cup creamy peanut butter
- 1/2 cup granulated sugar
- 1/2 cup light brown sugar, packed
- 1 large egg
- 1 teaspoon vanilla extract
- 1 1/4 cups all-purpose flour
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
Step-by-Step Instructions
Step 1: Prepare the Brownie Dough
- In a mixing bowl, whisk together the melted butter and sugar until smooth.
- Add the egg and vanilla extract, mixing well until fully incorporated.
- Sift in the cocoa powder, flour, salt, and baking powder. Stir gently until combined, being careful not to overmix.
- Cover the dough and refrigerate for at least 30 minutes to allow it to firm up.
Step 2: Prepare the Peanut Butter Cookie Dough
- In a large mixing bowl, cream together the softened butter, peanut butter, granulated sugar, and brown sugar until light and fluffy.
- Add the egg and vanilla extract, mixing until smooth.
- Gradually add the flour, baking soda, and salt, stirring until a soft dough forms.
- Cover and refrigerate for at least 30 minutes to make handling easier.
Step 3: Swirling the Doughs Together
- Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper.
- Take small portions (about 1 tablespoon each) of the brownie and peanut butter doughs. Gently press them together and roll into a ball.
- Lightly twist the dough ball to create a marbled swirl effect. Be careful not to over-mix the two doughs, or you’ll lose the distinct swirls.
- Place the dough balls onto the prepared baking sheet, spacing them about 2 inches apart.
Step 4: Baking to Perfection
- Bake in the preheated oven for 10–12 minutes, or until the edges are set but the centers are slightly soft.
- Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack. This helps them set properly while keeping the centers chewy.
Expert Tips for the Best Peanut Butter Brownie Swirl Cookies
- Chill the dough – Refrigerating the dough prevents the cookies from spreading too much, ensuring they retain a thick and chewy texture.
- Use high-quality cocoa powder – Opt for Dutch-processed cocoa for a richer, more intense chocolate flavor.
- Don’t overbake – These cookies will continue to firm up as they cool, so take them out when they’re slightly underbaked for the best texture.
- Experiment with add-ins – Try adding chocolate chips, chopped peanuts, or even a sprinkle of sea salt to enhance the flavors.
- Make them gluten-free – Swap out the all-purpose flour for a gluten-free flour blend to make them suitable for gluten-sensitive eaters.
Variations and Customizations
Want to switch things up? Here are some creative variations to try:
1. Double Chocolate Swirl Cookies
- Mix chocolate chips into both doughs for an extra chocolatey bite.
2. Nutty Delight Cookies
- Add crushed peanuts, almonds, or pecans for a crunchy contrast.
3. Salted Caramel Peanut Butter Brownie Swirl Cookies
- Drizzle caramel over the cookies before baking and sprinkle a bit of sea salt on top for a gourmet twist.
4. Espresso-Infused Cookies
- Add 1 teaspoon of instant espresso powder to the brownie dough for a mocha-inspired treat.
How to Store and Serve
Storage Tips
- Room Temperature: Store cookies in an airtight container for up to 5 days.
