Step‑by‑Step Instructions for Peanut Butter Brownie Cookies
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While it heats, line two baking sheets with parchment paper or silicone mats, ensuring an easy release for your warm cookies later. This is a crucial step to achieve the perfect chewy texture for your Peanut Butter Brownie Cookies.
Step 2: Mix Wet Ingredients
In a large mixing bowl, combine 1 cup of creamy peanut butter with ½ cup of brown sugar and ½ cup of granulated sugar. Use a whisk or electric mixer to blend them until smooth and well incorporated. Next, add in 2 large eggs, one at a time, mixing thoroughly, followed by 2 teaspoons of vanilla extract. The mixture should be creamy and inviting.
Step 3: Combine Dry Ingredients
In a separate bowl, whisk together ⅔ cup of all-purpose flour, ¼ cup of unsweetened cocoa powder, ½ teaspoon of baking soda, and ½ teaspoon of salt. Mix these dry ingredients well to break up any lumps in the cocoa powder, ensuring a uniform blend. This step is essential for achieving the rich flavor and ideal structure in your Peanut Butter Brownie Cookies.
Step 4: Combine Mixtures
Carefully fold the dry mixture into the wet ingredients in your large bowl. Stir gently until just combined to avoid overmixing; you want to see streaks of flour still present. Once combined, fold in 1 cup of semi-sweet chocolate chips and ½ cup of chopped peanuts if you choose. This adds delightful melty chocolate and nutty crunch to your cookies.
Step 5: Scoop the Dough
Using a cookie scoop or two tablespoons, portion the dough onto your prepared baking sheets, spacing them about 2 inches apart to allow for spreading. If you’d like, top each cookie with a few extra chocolate chips and a sprinkle of flaky sea salt for an added touch of flavor. The visual appeal will make your Peanut Butter Brownie Cookies irresistible!
Step 6: Bake the Cookies
Place the baking sheets in the preheated oven and bake for 10-12 minutes. Halfway through, rotate the sheets for even baking. Your cookies are done when the edges are set but the centers remain slightly soft—this is key for that chewy brownie-like texture.
Step 7: Cool the Cookies
Allow the cookies to cool on the baking sheets for about 5 minutes before transferring them to a wire rack. This step helps them set while remaining wonderfully chewy. Your Peanut Butter Brownie Cookies will continue to firm up as they cool, making them the perfect treat to enjoy once fully cooled!

Peanut Butter Brownie Cookies Recipe FAQs
What type of peanut butter should I use?
I recommend using regular, processed creamy peanut butter for the best results in these Peanut Butter Brownie Cookies. Natural peanut butter can lead to inconsistencies in texture and flavor due to its oil separation.
How should I store leftover cookies?
Store your cookies in an airtight container at room temperature for up to 1 week. For longer shelf life, they can be refrigerated in a separate airtight container for up to 2 weeks. Don’t forget to wrap them in wax paper first to avoid drying out!
Can I freeze Peanut Butter Brownie Cookies?
Absolutely! You can freeze these cookies for up to 3 months. To do this, place them in a freezer-safe bag or container, ensuring they are separated by parchment paper so they don’t stick together. When you’re ready to indulge, simply thaw at room temperature or reheat in the microwave for a few seconds.
What should I do if my cookies spread too much during baking?
If your Peanut Butter Brownie Cookies spread too much, it could be due to warm dough. I suggest chilling the dough for about 30 minutes before baking. This helps the cookies hold their shape and maintain a chewy texture. Also, ensure you’re measuring your flour accurately to achieve the right balance.
Are these cookies safe for those with nut allergies?
Since these cookies are primarily made with peanut butter, they are not suitable for anyone with peanut allergies. However, you can substitute with sunflower seed butter for a nut-free version, keeping in mind that this may alter the taste slightly.
Can I make these cookies gluten-free?
Yes, you can easily make gluten-free Peanut Butter Brownie Cookies! Simply replace the all-purpose flour with a 1:1 gluten-free baking blend. This ensures that everyone can enjoy these delicious treats without worry.
