    Red Velvet Ooey Gooey Bars have a red velvet cake mix cookie crust with marshmallow cream, rice krispies treats, and sprinkles on top.

    Red Velvet Ooey Gooey Bars Stack

    Since Valentine’s Day is just around the corner, I decided to make a Red Velvet Gooey Bars recipe. My first gooey bars recipe dates back to 2014 and it is still a family favorite, especially with my son.

    Something about the combination of the tender cake on the bottom, chewy and crispy rice krispies treats on top and the oozing marshmallow cream in the middle is pretty irresistible!

    How To Make Red Velvet Ooey Gooey Bars

    spreading marshmallow cream over red velvet cake layer

    Step One: Cake Layer

    Start by mixing together a red velvet cake mix, vegetable oil, and an egg. Spread this batter in a greased 8-inch square pan. Bake at 350°F for 10 to 12 minutes.

    Step Two: Marshmallow Layer

    Remove from the oven and top with a 7-ounce jar of marshmallow cream. Allow the marshmallow cream to melt and soften and then slowly spread it out over the bars with a greased silicone spatula.

    Step Three: Rice Krispies Layer

    Next, melt the butter in the microwave. Add mini marshmallows and stir to coat. Melt the marshmallows in the microwave for 45 seconds. Stir until smooth. If necessary, continue microwaving and stirring in 15-second intervals until smooth.

    Add red food coloring and stir. Add rice krispies and stir until combined. Scoop rice krispies treats onto the bars and spread out. I find that using my hand in a greased sandwich baggie works well.

    Step Four: Sprinkles

    Top the bars with heart shaped sprinkles and gently press them into the rice krispies treats.

    One of my brothers-in-law tasted ooey gooey bars for the first time when my son requested that I make them for our family Christmas. He got to try them again when I made this Red Velvet Ooey Gooey bars version for Valentine’s Day and he can’t say enough good things about them!

    The combination of the soft red velvet cake mix cookie layer with the ooey gooey marshmallow cream and crunchy rice krispies treats, is loved by kids of all ages.
