Tara’s Over the Top S’more Brownies
Nonstick cooking spray
6 Double Graham Crackers
1 (17.6 oz. package) Dark Fudge Brownie Mix
1 teaspoon Vanilla Extract
3 cups Miniature Marshmallows
11/2 cup Semisweet Chocolate Chips
.
Directions
Preheat oven to 350 degrees. Spray a 3.5 quart temp-tations baking dish with nonstick cooking spray.
Completely cover the bottom of the baking dish with a single layer of graham crackers.
In a large mixing bowl, prepare brownie mix according to package directions. Add vanilla extract, 1 cup of the miniature marshmallows, and 1/2 cup of the chocolate chips to the batter, gently fold in.
Pour the batter over the graham crackers, using a spatula to spread evenly throughout dish. Bake 30 to 40 minutes until set and a toothpick inserted into the center comes out mostly clean.
Remove the pan from the oven and sprinkle the remaining marshmallows and chocolate chips over the top. Bake 5 additional minutes and then let cool for 5 more. Slice into 16 squares and serve warm.
Tara’s Tip
The longer you let them cool, the less messy they will be to cut and eat. Cutting once cooled will result in a cleaner look that can still reheat in the microwave to serve warm. Still, I say that s’mores should be messy!
