Picture a warm peanut butter brownie swirl cookie, edges crackled and slightly crisp while the center stays luxuriously soft, with ribbons of nutty chocolate running through each bite.
These cookies are perfect for an after dinner snack, a weekend baking project, or a potluck dessert that will have everyone reaching for seconds.
SaveI first made them on a rainy afternoon and the whole kitchen smelled like a candy shop, making it one of those simple recipes that truly feels like a treat.
Peanut Butter Brownie Swirl Cookies Recipe
Ingredients
Cookie Dough
Brownie Swirl
Instructions
- Cream Butter and Sugars
In a large bowl beat the softened butter, granulated sugar, and brown sugar until pale, fluffy, and smooth, about 2 to 3 minutes.
- Add Egg and Peanut Butter
Whisk in the egg, vanilla, creamy peanut butter, then mix until fully combined and glossy.
- Whisk Dry Ingredients
In a separate bowl whisk together the flour, baking soda, and salt.
- Combine Dough
Gradually add the dry ingredients to the wet ingredients, mixing just until you have a soft cookie dough.
- Chill the Cookie Dough
Cover the bowl and chill the dough for at least 30 minutes or up to 72 hours for thicker cookies.
- Prepare the Brownie Swirl
Whisk the heavy cream, melted butter, cocoa powder, sugar, egg, salt, and vanilla in a bowl until smooth and lump free.
- Portion and Chill
Scoop tablespoonfuls of cookie dough onto a parchment lined tray, chill for 10 minutes so they hold their shape.
- Add Brownie Swirl
Spoon a small amount of brownie mixture over each dough ball, then use a toothpick to swirl and marble the two batters gently.
- Bake Until Set
Bake in a preheated 350°F (175°C) oven for 10 to 12 minutes, until the edges look set but the centers still appear slightly soft.
- Cool Completely
Let the cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool fully before enjoying.
Substitutions and variations
- Use natural peanut butter and stir it well, adding a little extra salt if needed.
- Swap the egg in the brownie mixture for a flax egg to make it vegan.
- Replace heavy cream with whole milk for a lighter version, the swirl will just be a bit looser.
- Use milk chocolate chips instead of cocoa powder and skip the brownie mix for a simpler cookie.
Chloe's tips
- For extra chew, slightly underbake the centers and rely on the residual heat to finish setting the edges.
- Use a cookie scoop for uniform size, which helps the cookies bake evenly.
- Store cooled cookies in an airtight container at room temperature for up to five days.
- If the brownie swirl stiffens while working with it, microwave it for 5 to 10 seconds to make it spreadable again.
How to store it
- Keep the fully cooled cookies in a sealed container at room temperature for up to 5 days.
- For longer storage, freeze the baked cookies in a single layer and transfer to a freezer bag for up to 3 months.
- To reheat, microwave a frozen cookie for 15 to 20 seconds or warm in a low oven for a few minutes.
Serving suggestions
These cookies are best served at room temperature so the swirls stay silky and easy to bite into.
- Place two cookies on a small plate with a glass of cold milk.
- Top a scoop of vanilla ice cream with a warm cookie for a simple dessert.
- Drizzle a little melted chocolate over the cooled cookies for extra indulgence.
Frequently asked questions
Why chill the cookie dough before baking?
Chilling helps prevent spreading, intensifies flavor, and gives you thicker, chewier cookies.
Can I use natural peanut butter, and will it change the texture?
Yes, you can use natural peanut butter, but it may make the dough slightly oilier. Stir it well and chill the dough to help maintain the shape.
How do I know when the cookies are done if the centers look soft?
The edges should be set and lightly cracked while the centers look slightly underdone; they will firm up as they cool on the baking sheet.
Can I make the brownies in advance and refrigerate them?
Yes, you can prepare the brownie mixture a day ahead, chill it in a sealed container, and use it when you are ready to swirl and bake.
