Fudgy walnut brownie cookies: How It’s Done

Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures your cookies bake evenly and get that perfect chewy texture.
Step 2: Melt the Chocolate and Butter
In a microwave-safe bowl, combine the chopped unsweetened chocolate and cubed butter. Microwave in 30-second intervals, stirring in between, until melted and smooth. Be careful not to overheat; you want a glossy mixture.
Step 3: Mix in Sugar and Vanilla
Once the chocolate and butter are melted and slightly cooled, whisk in the granulated sugar, salt, and vanilla extract. The mixture should be well combined and slightly thick.
Step 4: Add the Eggs
Crack in the two large eggs, one at a time, whisking thoroughly after each addition. This step is crucial for the cookies’ fudgy texture.
Step 5: Combine Dry Ingredients
In a separate bowl, whisk together the all-purpose flour and baking powder. Gradually add this dry mixture to the chocolate batter, stirring until just combined. Be careful not to overmix; you want your cookies to be soft and fudgy.
Step 6: Fold in Walnuts
Gently fold in 1/2 cup of the chopped walnuts. The remaining walnuts will be used for topping the cookies.
Step 7: Scoop the Dough
Using a cookie scoop or tablespoon, drop rounded balls of dough onto a baking sheet lined with parchment paper, leaving some space between each cookie.
Step 8: Top with Walnuts
Sprinkle the remaining chopped walnuts on top of the dough balls for extra crunch and visual appeal.
Step 9: Bake
Bake in your preheated oven for 10-12 minutes, or until the edges are set but the centers still look slightly soft. This will create that irresistible fudgy texture.
Step 10: Cool and Enjoy
Allow the cookies to cool on the baking sheet for about 5 minutes before transferring them to a wire rack to cool completely. This waiting period is essential, as it allows the cookies to set properly.
Variations for Dietary Needs

- Gluten-Free: Substitute all-purpose flour with a 1:1 gluten-free flour blend.
- Dairy-Free: Use dairy-free butter and ensure your chocolate is dairy-free.
- Nut-Free: Omit the walnuts or replace them with sunflower seeds for crunch.
- Lower Sugar: Reduce the granulated sugar by half or use a sugar substitute suitable for baking.
Problems & Prevention
- Cookies spreading too much: Ensure your butter is not too warm when mixing and chill the dough for 30 minutes before baking.
- Dry cookies: Avoid overbaking; check them a minute or two before the suggested time.
- Too crumbly: If the dough is too crumbly, you may need to add a teaspoon of water or milk to bring it together.
- Uneven baking: Rotate the baking sheet halfway through the baking time for even results.
Save for Later: Storage Tips
To keep your Fudgy walnut brownie cookies fresh, store them in an airtight container at room temperature for up to a week. If you want to keep them longer, you can freeze the cookies. Just make sure to layer them with parchment paper and place them in a freezer-safe bag for up to three months. To enjoy, simply thaw at room temperature or warm them briefly in the microwave.
Reader Q&A
Can I substitute the chocolate with cocoa powder?
While cocoa powder can be used, it will alter the texture and richness of the cookies. For the best results, stick to unsweetened chocolate.
What can I use instead of walnuts?
If you’re looking for an alternative, you can use pecans, almonds, or even skip the nuts altogether for a nut-free version.
How can I make these cookies extra chocolatey?
You can add chocolate chips to the dough before baking. Around 1/2 cup of semi-sweet or dark chocolate chips would elevate the chocolate flavor even more!
Can I make the dough ahead of time?
Absolutely! You can prepare the dough and refrigerate it for up to 48 hours. Just allow it to sit at room temperature for about 30 minutes before scooping and baking.
