Ingredients
  

Brownie Layer
  • 1 can (18 oz) brownie mix Use the ingredients required on the brownie mix package.
S'mores Layer
  • 1.5 cup mini marshmallows
  • 1 cup graham cracker pieces
  • 1 cup milk chocolate chunks
Patriotic Topping
  • 0.5 cup red candy melts Melt before drizzling.
  • 0.5 cup blue candy melts Melt before drizzling.
  • 2 tbsp patriotic sprinkles
  • 0.25 cup mini marshmallows Use as a topping after drizzling.

Equipment

  • 1 sheet pan

Method
 

Bake the brownie layer
  1. Preheat oven according to the brownie mix package directions. Set a greased 9×13-inch baking dish nearby.
  2. Prepare the brownie batter and pour it into the greased 9×13-inch baking dish. Spread into an even layer so it bakes uniformly.
  3. Bake until the brownies are almost fully set. Look for edges that look set while the center still has a slight jiggle.
Add the s'mores topping
  1. Remove the brownies from the oven and sprinkle graham cracker pieces, milk chocolate chunks, and mini marshmallows over the top. Distribute evenly for consistent bites.
  2. Return to the oven for 5–7 minutes until marshmallows are soft and lightly golden. Stop when the topping looks melted but not browned all the way.
  3. Cool completely. Let the brownies set so the topping doesn’t slide when you slice.
Finish and serve
  1. Drizzle melted red candy melts over the cooled brownies. Use thin lines for a striped, patriotic look.
  2. Drizzle melted blue candy melts over the brownies. Alternate drizzles to create a clear red-and-blue pattern.
  3. Sprinkle with patriotic sprinkles and extra mini marshmallows. Add while drizzles are still tacky for better adhesion.
  4. Slice into squares and serve. Use a clean cut for gooey, neat layers.

Notes

Pro tip: wait for the brownies to cool completely before slicing so the marshmallow layer stays intact. Store covered at room temperature for up to 3 days or refrigerate up to 5 days. Freeze assembled brownies (without cutting) up to 2 months, thaw overnight in the fridge. For a dairy-light swap, use dairy-free chocolate chunks and dairy-free candy melts if available.
