If you know me, you know that if a plate of fudgy brownies is anywhere in the room, I am absolutely going for one. There is just something about that rich, deeply chocolatey bite that makes any bad day instantly better. But you know what makes a classic brownie even more elite? Layering a thick, gooey blanket of buttery caramel and crunchy nuts right on top.
That is exactly how these Caramel Walnut Brownies came to life. I wanted a dessert that felt incredibly indulgent, had amazing texture, and was secretly so easy to whip up right in your own kitchen. Let me tell y’all, this recipe DELIVERS. You get an ultra-fudgy, crackly-topped brownie base loaded with chocolate chips, smothered in a smooth homemade caramel and chopped walnuts. Not to be dramatic—but these might be one of the best things to ever come out of my kitchen. They’ve got every texture going on: chewy, fudgy, crunchy, and all-around amazing.
How to Make Caramel Walnut Brownies
The beauty of this recipe is that the brownie batter comes together in just a few minutes, completely in one bowl—no fancy mixer required! You’ll start by melting your butter and sugar together in the microwave. Once that’s warm, you’ll whisk in your cold eggs and an extra yolk. Whisking vigorously for a full minute here is the secret to getting that gorgeous, shiny, crinkly top we all look for.
Next, you’ll stir in the vanilla, avocado oil, and cocoa powder. For the dry ingredients, we are using a mix of all-purpose flour, a touch of salt, and a tablespoon of cornstarch, which keeps the texture unbelievably tender and fudgy. We also sneak in a bit of instant espresso powder. Don’t worry, it won’t make them taste like coffee—espresso powder just amplifies the cocoa, making the chocolate taste a million times deeper and richer. Fold in your semisweet chocolate chips, spread the thick batter into a prepared 8×8 metal pan, and bake until just set.
While the brownies cool, it’s time for the crown jewel: the easy caramel topping. You’ll melt down a bag of caramels with a few tablespoons of evaporated milk in a saucepan until completely smooth and velvety. Stir in a generous handful of chopped walnuts (or pecans, if that’s your vibe!), pour it right over the cooled brownie base, and let it set before slicing.
Tips, Tricks, and Variations
- Vigorous whisking is key: Don’t skip whisking the eggs and sugar for a full minute. This dissolves the sugar into the eggs, creating that iconic, paper-thin crinkle crust on top of the brownies.
- Measure your flour correctly: Fluff your flour with a spoon, scoop it into the measuring cup, and level it off with a knife. Packing flour into the cup will make your brownies dense and cakey instead of fudgy.
- Don’t overbake: Brownies keep cooking as they cool in the hot pan. Take them out when a cake tester has moist crumbs attached—if it comes out completely clean, they are overdone!
- Let the caramel set: I know it is deeply tempting to slice into these immediately, but give the caramel layer an hour or two to solidify. It makes cutting them into clean, perfect squares a breeze. I also recommend using a sharp knife run under hot water to make cutting easier.
People Also Ask (FAQs)
Can I use a different type of nut? Absolutely! While walnuts provide that classic, earthy crunch that pairs perfectly with caramel, chopped pecans, sliced almonds, or even salted peanuts would taste incredible here. If you are nut-free, you can skip them entirely and add a sprinkle of flaky sea salt over the caramel instead.
Can I use boxed brownie mix? You can – just follow the instructions on the box, let cool, and then add the caramel topping layer. Note that box brownies may not be as dense as these and may crumble under the caramel layer a bit.
Can I use a glass baking dish instead of a metal pan? You can, but keep a close eye on the oven. Glass dishes retain heat differently than metal pans and can cause the edges to overcook before the center is set. If using glass, you may need to lower your oven temperature by 25°F or tent the pan if the sides are browning too fast.
How should I store these caramel brownies? Store your sliced brownies in an airtight container at room temperature for up to 3 to 4 days, or if you’ve added the caramel topping then store in the refrigerator for up to a week. They actually taste amazing chilled, as the caramel gets extra chewy and the brownie base stays super dense! If you’re making ahead, I recommend making the caramel the day you plan to serve and putting it on the brownies on that day.

Caramel Walnut Brownies
Equipment
- Mixing Bowls
- Oven
- 8×8 Pan
Ingredients
- 4 tablespoons unsalted butter
- 1 cup granulated sugar
- 2 large eggs plus 1 egg yolk cold
- 1 teaspoon vanilla extract or vanilla paste
- 6 tbsp avocado oil
- 3/4 cup cocoa powder
- 1/2 cup all-purpose flour measured correctly (about 63 grams)
- 1 tablespoon cornstarch
- 1/4 teaspoon salt
- 1.5 teaspoons instant espresso powder
- 1/2 cup semisweet chocolate chips
- 11 oz caramels
- 4.5 tbsp evaporated milk
- 3/4 cup chopped walnuts
Instructions
- Preheat your oven to 325°F and line an 8×8 metal baking pan with foil or parchment paper, spraying it well with nonstick cooking spray.
- Add the butter and granulated sugar to a microwave-safe bowl and heat for about 1 minute until the butter is completely melted. Let cool slightly, and then add the eggs and egg yolk to the warm butter mixture and whisk vigorously for one full minute.
- Whisk in the vanilla extract, then stir in the avocado oil and cocoa powder until smooth.
- In a separate bowl, combine flour, cornstarch, and salt, and then use a rubber spatula to gently stir the dry mixture into the wet mixture. Stir in the instant espresso powder, then fold in the semisweet chocolate chips.
- Spread the thick brownie batter evenly into your prepared baking pan. Bake for 28 to 30 minutes, removing them when the center is set and a toothpick comes out with a few moist crumbs attached.
- Remove from the oven and let the brownies cool completely in the pan so they can solidify.
- To make the topping, combine the caramels and evaporated milk in a saucepan over medium heat. Stir continuously as the caramels melt, heating until you have a completely smooth, melted sauce. Remove from the heat, add the chopped walnuts, and stir until the nuts are fully coated.
- Pour the warm caramel mixture directly over the cooled brownies, smoothing it out with a spatula to cover the top completely.
- Let the treats sit at room temperature or in the fridge for at least one to two hours to allow the caramel to fully set before slicing into 16 squares and serving.
