Ingredients
- ⅔ cup oil or melted butter
- ⅔ cup water
- 2 eggs
- 1 teaspoon vanilla extract
- 1½ cups granulated sugar
- 1½ cups cocoa powder
- 1⅓ cups all-purpose flour
- ½ teaspoon salt
- ½ teaspoon baking powder
- 2–3 cups assorted candy, chopped (Snickers, Kit-Kat, Reese’s, M&M’s, etc.)
Instructions
Step 1: Preheat the Oven
Preheat oven to 325°F and grease a 9×13-inch baking dish with nonstick spray.
Step 2: Mix the Wet Ingredients
In a large bowl, whisk together water, oil, vanilla extract, and eggs until smooth.
Step 3: Add the Dry Ingredients
Stir in sugar, cocoa powder, flour, salt, and baking powder until fully combined and glossy.
Step 4: Layer the Candy
Spread half the brownie batter into the prepared dish. Scatter half of the chopped candy evenly over the top. Pour the remaining batter over the candy and finish with the rest of the candy pieces.
Step 5: Bake
Bake for 50–60 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs. Avoid overbaking for fudgier brownies.
Step 6: Cool and Serve
Let the brownies cool completely before slicing. This allows the candy to set and the brownies to cut cleanly.
