If you’re hosting a gathering for the big game this year you’ve probably got a great list of tasty appetizers and finger food going but I’m here to remind you to include something sweet! These Brownie Marshmallow Crunch Bars are the perfect choice to satisfy your group of football fans. They are fudgy, decadent, and utterly delicious and there are no forks needed  – always a bonus at a gathering.

Another big bonus – this recipe starts with a box of Pillsbury™ Brownie Mix which means they’re fun and easy to put together.

If you’ve got little ones, or little ones visiting, it’s so fun to plan ahead for a simple recipe that you can do together. It never fails that when you have a group over, everyone ends up in the kitchen. So, why not put them to work! That’s my big boy, Connor with his girlfriend, Madison and her completely adorable son, Hunter. And, let me tell you, the party does not start until Hunter arrives. This little guy is so much fun.

Recipes that involve a boxed mix are the perfect choice when baking with little ones. If you go for something too complex, they’ll lose interest. Keep it simple, fun and delicious and they are guaranteed to have a good time and you’ll be creating memories that will last a lifetime. Depending on their age, there are all kinds of skills you can work on even with the simplest of recipes- measuring the ingredients – counting the 50 strokes it takes to combine the brownie batter – cracking the eggs. Letting them help with a recipe like this will bring instant gratification and build their kitchen confidence. It might seem like a small thing but this is huge!

Brownie Marshmallow Crunch Bars

Two items you’ll need for this recipe- Pillsbury™ Chocolate Fudge Brownie Mix and Vanilla Marshmallow Fluffy Frost™ .

Brownie Marshmallow Crunch Bars

Bake the brownies in  a 13″ x 9″ baking dish according to the package directions. Once they’ve cooled, spoon the Fluffy Frost™ over the top. Look at that amazing texture of this frosting! And, just wait until you taste it…

Brownie Marshmallow Crunch Bars

Gently spread the frosting over the brownies in an even layer.

When the mixture is completely melted and smooth, remove the pan from the heat and add 1-1/2 cups of crisp rice cereal. Stir well to combine.

Use an offset spatula or a plain ole’ butter knife to gently smooth the topping out in an even layer. Refrigerate the bars until the chocolate topping has set up.

This is going to be good…

    This looks amazing but my daughter doesn’t like peanut butter at all. Won’t touch the food just from the smell of it. What do you recommend to use as alternatives?
