Strawberry Upside-Down Cake

Sharing is caring!

My sister in law gave me a huge bag of frozen strawberries that she was not going to use. I’m not really a fan of strawberries myself, but of course I couldn’t let them go to waste. A friend of mine is dieting with me and she was craving dessert so I made this for her. The texture of the cake is similar to a tart rather than a cake.


  • 4 cups frozen sliced strawberries, thawed
  • 3 boxes (3 ounce) sugar free strawberry gelatin powder
  • 1+1/2 cups miniature marshmallows
  • 1 box white cake mix
  • 12 ounces sprite zero


Preheat oven to 325F.

Spray two round cake pans with cooking spray.

Spread 1/2 of the strawberries into the bottom of each pan.

Sprinkle the gelatin powder evenly over both of the pans.

Place the marshmallows in a single layer over the gelatin powder.

In a medium size bowl, blend the cake mix with the sprite zero, just until blended well.

Pour the batter evenly into each pan.

Bake for 20-25 minutes or until toothpick comes out clean.

Cool pans on a wire rack for 30 minutes.

Invert pan onto serving platter.

Stack cakes on top of each other or serve separately.

Refrigerate unused portions.
