To create these delightful Peanut Butter Brownie Cookies, gather the following key components:

For the Brownie Cookie Dough:

• Unsalted Butter (Melted): Adds richness and helps achieve the fudgy texture.
• Semi-Sweet Chocolate (Melted): Provides the deep chocolate flavor that forms the base of the cookie.
• Granulated Sugar & Brown Sugar: Balances sweetness while keeping the cookies soft and chewy.
• Eggs: Bind the ingredients together and add structure.
• Vanilla Extract: Enhances the overall flavor profile with its warm, aromatic notes.
• All-Purpose Flour: Provides structure and ensures a tender crumb.
• Unsweetened Cocoa Powder: Delivers a rich chocolate taste without adding extra sweetness.
• Baking Powder & Salt: Essential for leavening and balancing the sweetness.

For the Peanut Butter Swirl:

• Creamy Peanut Butter: Offers the iconic nutty flavor and creamy texture.
• Powdered Sugar: Sweetens the peanut butter swirl and ensures smoothness.
• Vanilla Extract: Adds depth to the peanut butter mixture.

Optional Add-Ins:

• Chocolate Chips: For extra gooeyness and bursts of chocolate.
• Chopped Peanuts: Adds crunch and enhances the peanut butter theme.
• Sea Salt Flakes: Sprinkle on top for a salty-sweet contrast.

Step-by-Step Instructions

Prepare the Brownie Cookie Dough:

1. Preheat Oven: Set your oven to 350°F (175°C) and line a baking sheet with parchment paper. This ensures even baking and easy cleanup.
2. Melt Chocolate & Butter: In a microwave-safe bowl, melt unsalted butter and semi-sweet chocolate in 30-second intervals, stirring until smooth. Let the mixture cool slightly to avoid scrambling the eggs when added later.
3. Whisk Sugars & Eggs: In a large mixing bowl, whisk together granulated sugar, brown sugar, eggs, and vanilla extract until light and fluffy. This step incorporates air into the dough, contributing to the cookies’ chewy texture.
4. Combine Wet & Dry Ingredients: Sift all-purpose flour, unsweetened cocoa powder, baking powder, and salt into the wet mixture. Stir until just combined to avoid overmixing, which can lead to tough cookies. Then, fold in the melted chocolate mixture until fully incorporated.

Make the Peanut Butter Swirl:

1. Mix Peanut Butter & Sugar: In a small bowl, stir together creamy peanut butter, powdered sugar, and vanilla extract until smooth. This creates a sweet, spreadable peanut butter mixture that complements the rich chocolate dough.

Assemble & Bake:

1. Scoop Dough: Drop spoonfuls of brownie cookie dough onto the prepared baking sheet, spacing them about 2 inches apart to allow for spreading.
2. Swirl in Peanut Butter: Add small dollops of the peanut butter mixture on top of each dough ball. Use a toothpick or knife to gently swirl the peanut butter into the dough without over-mixing. This creates beautiful marbled patterns.
3. Bake: Place the baking sheet in the preheated oven and bake for 10-12 minutes, or until the edges are set but the centers remain slightly soft. These cookies firm up as they cool, so avoid overbaking.
4. Cool & Enjoy: Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely. Serve warm or at room temperature for the ultimate treat.

Love experimenting with flavors? Here are some fun ways to customize your Peanut Butter Brownie Cookies:

• Double Chocolate Peanut Butter Cookies: Add chocolate chips to the dough for extra gooeyness.
• Crunchy Peanut Butter Version: Use crunchy peanut butter instead of creamy for added texture.
• Salted Peanut Butter Cookies: Sprinkle sea salt flakes on top for a salty-sweet balance.

• Vegan Version: Use dairy-free chocolate and replace eggs with flax eggs (1 tablespoon ground flaxseed + 2.5 tablespoons water per egg).

Storage and Reheating Tips

Proper storage ensures your cookies stay fresh and delicious:

• Room Temperature: Store in an airtight container for up to 4 days.
• Refrigerator: Extend freshness by refrigerating for up to a week.
• Freezing: Freeze unbaked dough balls in a sealed bag for up to 3 months. Bake from frozen, adding 2 extra minutes to the baking time.

For reheating, microwave a cookie for 10 seconds to restore its gooey, melty texture.

Frequently Asked Questions

Here are answers to common questions about this recipe:

Can I use natural peanut butter?
Yes, but make sure to stir it well, as it’s thinner than regular peanut butter. If it’s too runny, mix in a teaspoon of powdered sugar to thicken it.

How do I keep my cookies soft?
Don’t overbake! Remove the cookies when they look slightly underdone, as they firm up while cooling.

Can I use Dutch-process cocoa powder?
Absolutely! Dutch-process cocoa powder gives a deeper chocolate flavor but may require an extra pinch of baking powder for proper leavening.

Why did my cookies spread too much?
If the dough is too warm, chill it for 15 minutes before baking. Also, ensure you’re using parchment paper instead of greased pans to prevent excessive spreading.

Can I make these cookies ahead of time?
Yes! Prepare the dough and refrigerate it for up to 2 days before baking.

What’s the best way to swirl the peanut butter?
Use a toothpick or knife to gently mix the peanut butter into the dough without over-mixing. This creates beautiful marbled patterns.

Can I use white chocolate instead of semi-sweet?
Absolutely! White chocolate pairs beautifully with peanut butter and adds a creamy sweetness.

How do I get thicker cookies?
Chill the dough before baking and use parchment paper instead of greased pans to help maintain shape.

Can I add peanut butter to the cookie dough instead of swirling it?
Yes! Mix 2 tablespoons of peanut butter directly into the batter for an all-over nutty flavor.

Do these cookies taste like brownies?
Yes! They have a rich, fudgy brownie texture with crispy edges and a gooey center, making them the perfect hybrid dessert.
