How to Make Peanut Butter Brownie Cookies
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone mats to prepare them for baking.
Step 2: Mix Wet Ingredients
In a large bowl, whisk together the peanut butter, brown sugar, and granulated sugar until well combined. Then add the eggs one at a time while whisking continuously. Finally, stir in the vanilla extract until everything is smooth and glossy.
Step 3: Combine Dry Ingredients
In another medium bowl, whisk together the flour, cocoa powder, baking soda, and salt until well mixed.
Step 4: Combine Wet and Dry Mixtures
Carefully stir the dry mixture into the wet mixture until just combined. Be careful not to overmix; this will help maintain that chewy texture.
Step 5: Add Mix-ins
Gently fold in the semi-sweet chocolate chips and chopped peanuts if you’re using them.
Step 6: Scoop Dough onto Baking Sheets
Use a cookie scoop to portion out dough onto your prepared baking sheets. Space each cookie about 2 inches apart to allow room for spreading during baking.
Step 7: Top with Extra Chocolate Chips
If desired, sprinkle extra chocolate chips on top of each cookie dough mound along with flaky sea salt.
Step 8: Bake Cookies
Bake in your preheated oven for 10–12 minutes. Rotate the sheets halfway through cooking; edges should be set while centers remain slightly soft.
Step 9: Cool on Baking Sheets
Once baked, let cookies cool on the sheets for about 5 minutes before transferring them to a wire rack to cool completely.

How to Perfect Peanut Butter Brownie Cookies
To achieve the best texture and flavor in your Peanut Butter Brownie Cookies, follow these helpful tips:
-
Use Room Temperature Eggs: Using eggs at room temperature allows them to incorporate better into the batter, resulting in a smoother consistency.
-
Don’t Overmix: Mix until just combined to maintain the cookie’s chewy texture. Overmixing can lead to tough cookies.
-
Chill the Dough: For thicker cookies, chill the dough for 30 minutes before baking. This helps them maintain their shape while cooking.
-
Rotate Baking Sheets: Halfway through baking, rotate your sheets. This ensures even cooking and prevents one side from being overdone.
-
Adjust Baking Time: Keep an eye on your cookies; every oven is different. Bake until edges are set, but centers should remain slightly soft for the perfect chewiness.
-
Add Extra Toppings: Get creative! Consider adding peanut butter chips or additional chocolate chips before baking for extra flavor and texture.

Common Mistakes to Avoid
Making Peanut Butter Brownie Cookies can be a breeze, but certain mistakes can hinder your results. Here are some common pitfalls to watch out for:
-
Using Cold Eggs: Always use room temperature eggs. Cold eggs can cause the mixture to curdle and not blend well.

Overmixing the Dough: Mix until just combined. Overmixing can lead to tough cookies instead of tender, chewy bites.
-
Not Measuring Ingredients Accurately: Use a kitchen scale or proper measuring cups. Inaccurate measurements can affect texture and taste.
-
Skipping the Chocolate Chips: Don’t skip the chocolate chips! They add essential flavor and richness, making your cookies truly irresistible.
-
Baking at the Wrong Temperature: Ensure your oven is preheated correctly. Baking at too low or high a temperature can result in undercooked or burnt cookies.
