How to Make Lemony Rhubarb Upside Down Cake

Preheat oven to 350°F (175°C). Grease and flour a 13x9 inch baking pan.
In the prepared pan, arrange a layer of 4 cups chopped rhubarb, followed by 1 cup granulated sugar, 1 cup mini marshmallows, and 1 (3 oz) package of lemon-flavored gelatin.
Prepare your favorite lemon cake mix according to package directions. (Most mixes call for adding eggs, oil, and water; follow your mix's instructions.)
Gently pour the prepared cake batter evenly over the rhubarb mixture in the pan.
Bake for 50-60 minutes, or until a wooden skewer inserted into the center comes out clean.
Let the cake cool completely in the pan for at least 30 minutes.
Carefully invert the cake onto a large plate or serving platter lined with parchment paper to prevent sticking.
Cut into squares and serve. Enjoy!
