Jump to RecipeCostco Triple Chocolate Brownie Recipe Ingredients
- ¾ cup butter, melted (regular or dairy-free)
- ¾ cup light brown sugar
- 1 cup granulated sugar
- 2 eggs
- 1 tablespoon vanilla extract
- ¾ cup cocoa powder
- ¼ teaspoon salt
- ½ cup + 2 tbsp all-purpose flour
- ⅓-½ cup white chocolate chips (or chopped chocolate)
- ⅓ cup semisweet or dark chocolate chips (or chopped chocolate)
- ¼-⅓ cup milk chocolate chips (or chopped chocolate)
How To Make Costco Triple Chocolate Brownies
- Prep Oven and Pan: Preheat the oven to 350°F. Line an 8×8-inch square baking pan with parchment paper, leaving an overhang on the sides to act as handles.
- Mix Wet Ingredients: In a medium-sized bowl, add the melted butter and both the brown and granulated sugars. Whisk vigorously until the mixture resembles a thick paste that pulls away from the sides of the bowl. Add the eggs and vanilla and whisk again until smooth.
- Combine the Batter: Add the cocoa powder, salt, and flour to the bowl. Whisk until the ingredients are just combined. Be careful not to overmix.
- Add Chocolate and Bake: Gently fold in all three types of chocolate chips. Pour the batter into the lined baking pan and use a spatula to spread it into an even layer.
- Bake the Brownies: Bake for 30 to 40 minutes. Start checking for doneness at the 30-minute mark. The brownies are ready when the top is crinkly and a toothpick inserted into the center comes out with a few moist crumbs, but not wet batter.
- Cool Completely: Let the brownies cool completely in the pan on a wire rack before using the parchment handles to lift them out and slice them.
Recipe Tips
- How do I get a perfectly fudgy brownie? The key to a fudgy, gooey center is to not overbake. The brownies are ready to come out of the oven when a toothpick has moist crumbs attached, not when it’s perfectly clean. They will continue to set as they cool.
- How do I get that shiny, crinkly top? Vigorously whisking the melted butter and sugars together until they form a paste, and then whisking in the eggs, helps to create that signature shiny, paper-thin crust on top of the brownies.
- Can I use a different pan? Yes. To double the recipe, use a 9×13-inch pan and bake for 20-35 minutes. If you use a glass baking dish instead of a metal one, the brownies may take a few minutes longer to bake.
- Why do the brownies need to cool completely? Fudgy brownies are very soft and delicate when they first come out of the oven. Letting them cool completely in the pan allows them to set up properly so they can be sliced into clean squares without falling apart.
What To Serve With Triple Chocolate Brownies

How To Store Triple Chocolate Brownies

FAQs
Yes, this recipe is easily adapted to be dairy-free. Simply use a dairy-free butter substitute (in block form is best) and ensure that all three types of your chocolate chips are certified dairy-free.
Yes, brownies freeze very well. Once they are completely cool, you can wrap the entire slab or individual squares tightly in plastic wrap and then in foil. They can be frozen for up to 3 months. Thaw at room temperature.
A cakey texture is usually the result of over-mixing the batter after the flour has been added, or of overbaking. Mix only until you no longer see streaks of flour, and pull the brownies from the oven when the center is still slightly soft for the fudgiest result.
