Ingredients
To make the Peanut Butter Brownie Swirl Cookies, you need the following items:

- 1/2 cup granulated sugar
- 1/2 cup brown sugar, packed
- 1 large egg
- 1 teaspoon vanilla extract
- 1/2 teaspoon baking soda

- Optional: 1/4 cup chocolate chips for extra gooeyness
These ingredients work together to create a rich, sweet flavor. Creamy peanut butter gives the cookies a great texture. The sugars add sweetness and help the cookies rise. The egg binds everything together, and vanilla adds a lovely aroma.
Baking soda helps the cookies puff up. Flour gives structure to the dough. The brownie batter swirls in to add a rich chocolate flavor. If you want extra chocolate, toss in chocolate chips for an even richer taste.
Gather these ingredients before you start, and you’ll be ready for a fun baking session!

Step-by-Step Instructions
Preheat the Oven
First, set your oven to 350°F (175°C). This step warms up the oven for baking. Next, line a baking sheet with parchment paper. This keeps cookies from sticking and makes cleanup easy.
Mix Peanut Butter Base
In a mixing bowl, take 1 cup of creamy peanut butter. Add 1/2 cup of granulated sugar and 1/2 cup of brown sugar. Mix them together until smooth and creamy. This base gives your cookies a rich peanut flavor.
Add Wet Ingredients
Next, crack 1 large egg into the bowl. Add 1 teaspoon of vanilla extract for flavor. Beat these wet ingredients into the peanut butter mixture until well combined. This adds moisture and helps bind the dough.
Incorporate Dry Ingredients
Now, sprinkle in 1/2 teaspoon of baking soda and 1/4 teaspoon of salt. Then, add 1/2 cup of all-purpose flour. Stir these dry ingredients into the mixture. Be careful not to over-mix, as this can make the cookies tough.
Prepare Brownie Batter
If you use a store-bought brownie mix, prepare it according to the package directions. If you prefer homemade, make your favorite brownie batter. This adds a delicious chocolate layer to your cookies.
Swirl It Up
Using a cookie scoop or tablespoon, drop a spoonful of peanut butter cookie dough onto the baking sheet. Then, take a different spoon and add a dollop of brownie batter on top. This creates a fun mix of flavors.
Create Swirls
To make the marbled effect, use a toothpick or knife. Gently swirl the brownie batter into the peanut butter dough. Be sure to create beautiful designs without fully mixing them together.
Bake
Place the baking sheet in the oven. Bake for 10 to 12 minutes. The edges should be set, while the center remains slightly soft. After baking, let them cool on the sheet for a few minutes before transferring them to a wire rack.
Optional Topping
For extra sweetness and gooeyness, sprinkle 1/4 cup of chocolate chips on top of the cookies right after you take them out of the oven. The heat will melt the chips slightly, making them irresistible.
Tips & Tricks
Achieving the Best Texture
To get the perfect texture in your Peanut Butter Brownie Swirl Cookies, you can choose between chewy or cakey. For chewy cookies, use less flour and bake them until just set. If you want them cakey, add a bit more flour and bake until firm. Each method gives a different feel, so try both!
Common Mistakes to Avoid
Avoid over-mixing your dough. This can make your cookies tough. Mix until just combined. Also, be careful not to underbake. The edges should be firm, but the center can stay soft. Let them cool on the pan for a few minutes to finish setting.
Presentation Suggestions
To impress your guests, serve these cookies on a rustic wooden platter. Pair them with a cold glass of milk for a classic treat. If you want a fancy touch, lightly dust the cookies with powdered sugar. This adds a nice look and a hint of sweetness.
Pro Tips
- Use Room Temperature Ingredients: Allow your peanut butter and egg to come to room temperature before mixing. This helps create a smoother batter and better blending of ingredients.
- Don't Overmix the Dough: Mix just until the flour is incorporated. Overmixing can lead to tough cookies.
- Chill the Dough for Better Swirls: If your dough is too soft to swirl easily, chill it in the refrigerator for 15-20 minutes to firm it up before baking.
- Experiment with Different Brownie Mixes: Try using different flavored brownie mixes, like salted caramel or mint, to create unique variations of these cookies.
Variations
Adding Different Mix-Ins
You can make your Peanut Butter Brownie Swirl Cookies even more special. Adding nuts gives them a nice crunch. Try walnuts or pecans for a rich taste. You can also add different types of chocolate. Dark chocolate chunks or milk chocolate chips work great. Each mix-in changes the flavor, making them fun to customize.
Substituting Ingredients
If you want to change things up, consider swapping some ingredients. You can use almond flour or oat flour instead of all-purpose flour. This adds a unique taste and texture. For a sweeter flavor, try honey or maple syrup instead of sugar. These swaps can make your cookies unique while still being yummy.
Dietary Adjustments
Making these cookies fit different diets is easy. To make them gluten-free, just use a gluten-free flour blend. For a vegan option, replace the egg with a flax egg. Mix one tablespoon of flaxseed meal with three tablespoons of water. Let it sit until it thickens. These adjustments let everyone enjoy these tasty treats, no matter their diet.
