    Butterfinger Ooey Gooey Bars Recipe

    Butterfinger brownie bars recipe

    Today is the first day of school for my kids and even though it was definitely time for them to go back, once they are gone I’m always a little sad. My baby started middle school and that is so strange to me. He will do great though and he has his big sister there to look out for him. It’s the kind of day where everyone deserves a big treat like these Butterfinger Ooey Gooey Bars! They have a brownie crust, Butterfinger Rice Krispies Treats on top and marshmallow cream sandwiched between.

    Brownies

    These bars start with a simple 9 inch pan of brownies. You can use your homemade recipe or go the boxed route.

    Ooey Gooey Bars Recipe

    When you pull the brownies out of the oven, while they are still hot, top them with a jar of marshmallow cream. You can just put it in big plops on the brownies. The marshmallow cream will spread out on its own and then you can smooth it out more before adding the Rice Krispies Treats layer. While the brownies are cooling, chop about 10 fun size Butterfingers or enough to make about 1 1/4 cups.

    Next, make the Butterfinger Rice Krispies Treats. Microwave 1 1/2 tablespoons of butter for 20 seconds in a large bowl, until melted. Add 3 cups of mini marshmallows and stir to coat. Microwave for 45 seconds and stir until smooth. (If the marshmallows aren’t completely melted, microwave for an additional 30 seconds.) Mix in 2 1/2 cups of Rice Krispies. Then, stir in 3/4 cup chopped Butterfingers.

    Drop by large spoonfuls over the marshmallow cream layer and carefully spread out evenly. I put my hand in plastic baggie with a little butter on it and gently spread it out and patted it down. Then, firmly press the top layer down into the marshmallow cream to really hold things together.

    Chocolate drizzle

    Melt semi-sweet chocolate chips and shortening in the microwave for 45 seconds, stir and continue heating at 15 second intervals until smooth. Drizzle or spread the melted chocolate over the bars.

    You can leave the bars as is, with the melted chocolate as the topping or you can go overboard and sprinkle the bars with 1/2 cup of chopped Butterfingers. Cover the bars and cool completely in the fridge.

    As the chocolate hardens, it will help keep the Butterfinger bits in place, but between the gooey marshmallow and the chopped candy bars this dessert tends to be a little messy!

    Cut these Butterfinger Ooey Gooey Bars just before serving. They are very rich, so make sure to cut them into small bars.

      Do you think that using Cool Whip instead of the marshmallow cream would work as well flavor wise? I’m just curious plus I think it would be a little less messy, but I’m not sure I don’t bake often!

        Hi Ashlee,
        I’m not sure that Cool Whip would be sturdy enough to hold up the top layer of Rice Krispie bars. I think they would just sink into the Cool Whip. I’m sure if would taste delicious though! Happy Baking!
