Ingredients

Preheat the oven to 325°F and line an 8x8-inch baking pan with parchment paper and set aside.
Add the 1 (18 oz. box) brownie mix, 2 large egg yolks, ⅓ cup vegetable oil or butter, ¼ cup hot brewed coffee or espresso, and 1 teaspoon vanilla extract and mix just until combined and no streaks of flour remain. Do not overmix.
Pour the batter into the prepared pan and smooth out with a rubber spatula.
Bake for 40 to 45 minutes or until the top has a nice film and a toothpick comes back from the center with a few crumbs.
Notes
Hot brewed coffee can be replaced with hot water and 1/2 teaspoon of espresso powder.
We're pretty partial to Ghirardelli, preferably the Double Chocolate, Dark Chocolate, and Triple Chocolate varieties. If you want to make these gluten-free, I recommend using the King Arthur brand mix. Betty Crocker, Pillsbury, and Duncan Hines are good options too.
If you need more servings, I recommend tripling this recipe and baking it in a 9x13-inch pan. This gives you thicker, fudgier brownies.
Store in an airtight container at room temperature for 3 to 4 days.
