Brownies! The perfect basic chocolate dessert. So many recipes, so many variations – cocoa or melted chocolate; nuts or no nuts; chewy or cake-y – but definitely no frosting!!
I love brownies, but I am notoriously mediocre at making them. Late in life, I think I have finally mastered the art of a good brownie. The base of this is from Katharine Hepburn’s recipe, but it uses salted mixed nuts.
This is a really good, chewy brownie, with salty, crunchy nuts. Each bite is a bit of a “you never know what you’re gonna get” experience. Different nuts in each bite! Of course, you can use just one type of nuts – or none at all!

Why You’ll Love This Recipe
- One-Bowl recipe: No fancy equipment, just melt, stir, and bake.
- Perfectly Fudgy: This ratio of sugar, butter, and cocoa gives you that perfect gooey center with a crispy edge.
- Salty-Sweet Combo: Salted mixed nuts bring great texture and balance.
Ingredients Needed
- Cocoa: The chocolate base of the brownies. Make sure to use unsweetened cocoa powder.
- Butter: Adds richness and fudgy texture.
- Eggs: Use free-range for best flavor.
- Sugar: Sweetens the batter and helps create that shiny brownie top. You can cut down the amount a tiny bit, but not by more than 1/4 cup.
- Flour: Just enough to bind the brownies without making them cakey. You can use gluten-free.
- Chopped Salted Mixed Nuts: Adds crunch and salty contrast. You can use any combo of almonds, peanuts, cashews, pecans, or walnuts. Even honey-roasted nuts or a spicy mix with chili powder would work.
- Vanilla: Enhances the chocolate flavor. Use paste or essence.
- Pinch of Salt: Brings out the chocolate and balances the sweetness.

- Preheat oven to 325F. Grease an 8 x 8 inch baking pan with butter and set aside.
- Melt butter in a saucepan over low heat. Add cocoa and mix well. Remove from heat and cool for a few minutes.
- Add butter-cocoa mixture to a mixing bowl. Whisk in eggs, one at a time. Stir in vanilla.
- In a separate bowl, stir together sugar, flour, nuts and salt. Add to the cocoa mixture and stir lightly to combine.
- Pour into prepared pan. Bake 30-35 minutes. Do not overbake; brownies should be gooey. Cool, then cut into bars.



Helpful Tips
- Don’t overbake these! These brownies should be gooey in the center. A toothpick should come out with moist crumbs. If unsure, better to take them out of the oven earlier than too late.
- I like my brownies with coarsely chopped nuts. Big nut chunks make every bite interesting.
- For a deeper chocolate flavor, add ½ tsp of instant espresso powder to the cocoa mixture.
- Don’t forget to line the pan with parchment paper for easy removal.
