Method
- Preheat your oven to 350°F. Line an 8x8-inch baking dish with parchment paper and spray the parchment with nonstick cooking spray.Nonstick cooking spray
- In a large mixing bowl, combine the boxed brownie mix, sweetened condensed milk, and eggs.1 box store-bought brownie mix, 1 can sweetened condensed milk, 2 large eggs
- Use a wooden spoon or sturdy spatula to mix the ingredients by hand until just combined and no dry spots of brownie mix remain. Be careful not to overmix. The batter will be thick.
- Pour the thick batter into the prepared baking dish and spread it into an even layer.
- Bake for about 30 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs attached. If wet batter remains, bake for 5 more minutes and check again.
- Remove the brownies from the oven and let them cool completely in the pan on a wire rack.
- Once cool, use the parchment paper to lift the brownies out of the pan. For the cleanest slices, refrigerate the brownies for 15 minutes to firm up.
- Place the chilled brownies on a cutting board and slice into squares. Serve and enjoy.
Notes
For perfectly clean slices, chill the cooled brownies for 15 minutes before cutting. For a flavor twist, swirl in 2 tablespoons of melted peanut butter into the batter before baking.
