Brownie Peanut Butter Cookie Ingredients
- All Purpose Flour: Regular, plain, all purpose flour is perfect for a fudgy cookie.
- Unsweetened Cocoa Powder: Unsweetened cocoa powder is part of what gives the cookies a deep chocolate flavor. I use natural cocoa powder, but dutch processed should work too!
- Baking Powder: Baking powder gives these cookies a rise and gorgeous dome!
- Salt: Salt brings out sweetness and enhances the overall flavor.
- Corn Starch: Corn starch is the secret to a soft and chewy cookie.
- Dark Chocolate Chips: You will melt chocolate chips down before adding them to the batter.
- Unsalted Butter: Room temperature unsalted butter gives these cookies the best flavor and texture!
- Light Brown Sugar & Granulated Sugar: Both sugars work together to create a chewy, moist, and structured brownie cookie.
- Eggs & Egg Yolk: 2 eggs and an egg yolk contribute to moisture and texture. Do not skip the egg yolk because you will end up with flat cookies.
- Vanilla Extract: Vanilla extract rounds out the flavor of these peanut butter chocolate cookies!
Step by Step Process
STEP 1: Preheat your oven to 350 degrees Fahrenheit. Line baking sheets with parchment paper to ensure the cookies come off of the pan cleanly.
STEP 2: In a medium bowl, whisk all purpose flour, cocoa powder, baking powder, salt, and corn starch together until the ingredients combine.
STEP 3: In a large bowl with a hand mixer or in the bowl of a stand mixer fitted with a paddle attachment, beat room temperature butter, light brown sugar, and granulated sugar together until smooth. This should be 2-3 minutes of mixing on high speed.
STEP 4: Add eggs, egg yolk, and vanilla extract to the batter. Beat on medium speed until smooth. Use a spatula to scrape down the sides and the bottom of the bowl to ensure the ingredients are combined throughout.
STEP 5: Pour your melted dark chocolate chips into the batter and mix on medium speed until the chocolate is dispersed throughout the batter.
STEP 6: Next, add the dry ingredients to the bowl of wet ingredients. Beat the two together on low speed until smooth. Do not mix past when you see the flour mixture disappear to avoid dense, dry cookies. Let the mixture sit and firm up at room temperature for 10 minutes before rolling.
STEP 7: Then, roll the dough into about 1 ½-2 tablesoon-sized (55g) balls. Place the balls at least 2 inches apart from each other on a baking sheet.
STEP 8: Bake the cookies for 10-13 minutes until the tops are domed and slightly shiny and cracked. Prepare the peanut butter filling while the cookies are baking.
Peanut Butter Filling
STEP 1: While your cookies are baking, combine powdered sugar and creamy peanut butter together. You can hand mix with a spoon or use an electric mixer on low speed until the mixture is combined.
STEP 2: Roll the mixture into about 1 tablespoon-sized balls. These balls should be rolled and ready by the time your cookies come out of the oven.
STEP 3: After the cookies have been removed from the oven, push one peanut butter ball into the top of each cookie.
Frequently Asked Questions
Traditional buckeyes are smooth peanut butter balls dipped in chocolate. The peanut butter filling is similar to that of a peanut butter cup.
To avoid flat cookies, make sure your butter is not too warm, you allow the batter to sit at room temperature for 10 minutes before rolling, you do not put your dough on warm baking sheets, and do not underbake to prevent the cookies form falling as they cool.
These cookies are SO fudgy if you measure your flour properly, you do not mix past when the ingredients combine when adding the dry ingredients to the wet ingredients, and you bake only until the cookies are shiny and domed but slightly soft in the center.
Expert Tips & Tricks
Measuring Flour: These brownie cookies are fudgy, chewy, and soft. However, if you measure your flour incorrectly, they will come out dry. Measure flour with a kitchen scale or by using a spoon to transfer your flour from its container to your measuring cups before taking a knife to sweep across the top to level it.
10-Minute Sit Time: Before you roll the dough into balls, let the mixture sit at room temperature to firm up. This helps create thicker, rounder cookies.
Storing: Once the chocolate has completely set, store these cookies in an airtight container or tightly covered at room temperature for up to 4 days or in the freezer for up to 4 months.

- Let the cookies fully cool and chocolate fully set before storing them in an airtight container or tightly covered at room temperature for up to 4 days or in the freezer for up to 4 months.
Mixing: Do not mix past when you see the dry ingredients disappear into the wet batter to ensure the cookies are chewy and fudgy.
Sit Time: Make sure to let your batter sit at room temperature for 10 minutes to firm up before rolling the dough into balls. If you skip this step, your cookies could end up flatter.
