Ingredients

Scale

1 box Betty Crocker brownie mix, 18.3 oz
2 large eggs
0.5 cup vegetable oil
0.25 cup water
0.5 cup chopped walnuts
1 fudge swirl packet (if included) or 2-3 Tbsp chocolate syrup
0.5 tsp vanilla extract (optional)
Pinch sea salt (optional)
0.25 cup chocolate chips (optional)

Instructions

Preheat Oven and Prepare Pan: Preheat oven to the temperature specified on the mix box (usually 325-350°F). Lightly grease and flour an 8×8 or 9×13 inch baking pan, or line it with parchment paper for easy removal.
Combine Wet and Dry Ingredients: In a large bowl, combine the Betty Crocker brownie mix, eggs, oil, and water. Stir just until moistened (about 30 seconds), then beat by hand for 50 strokes until the batter is smooth and shiny. (If batter looks too thick, add an extra teaspoon of water). Avoid overmixing.
Fold In Walnuts and Layer Batter: Gently fold in the 0.5 cup chopped walnuts until just distributed. Spread about half of the prepared batter evenly into your pan, ensuring it forms a smooth layer.
Create Fudge Swirl: If your mix includes a fudge packet, dollop half of it over the batter. Using a knife, lightly swirl it through. Add the remaining brownie batter, then dollop the rest of the fudge and swirl again to create beautiful patterns on top.
Bake Brownies: Bake for the time recommended on your mix box (typically 28-35 minutes for fudgy results, or slightly longer for cake-like). A toothpick inserted 2 inches from the pan’s side should come out with moist crumbs, not wet batter, indicating perfect doneness.
Cool Completely Before Serving: Allow the brownies to cool completely in the pan on a wire rack, which takes about 1-2 hours. This step is crucial for achieving clean cuts and ensuring maximum fudginess and flavor.

Notes

For extra fudgy brownies, reduce baking time by 2-3 minutes or add an extra egg yolk. Avoid overbaking to prevent dryness; a toothpick should have moist crumbs. For a richer flavor, swap vegetable oil for melted unsalted butter (1:1 ratio). Store cooled brownies in an airtight container at room temperature.
