Ingredients & Equipment Needed For This Recipe


  • Fresh Raspberries– I didn’t try with frozen raspberries for this recipe. I imagine that if they thaw out and all of the moisture has been removed it should work.
  • Mini Marshmallows– Regular size is too big for this recipe.
  • Yellow or White Cake Mix of Choice– I used yellow cake mix from Betty Crocker for mine!


  • 1 Cup Measuring Cup– To measure the marshmallows.
  • Large Mixing Bowl– For mixing the cake batter
  • Whisk or Rubber Spatula
  • 9″X13″ Baking Dish– I used a metal one but I can imagine glass would work as well.
  • Pan Spray– To coat the baking dish so the cake doesn’t stick

My Kinda Professional Tips For Raspberry Upside Down Cake

  • Make sure to spray the baking dish very well. This can get a little sticky on the bottom. For extra security you can add parchment paper as a liner on the bottom of the baking dish.
  • Use a toothpick or cake tester to make sure the cake is done. No one wants an under baked cake!
  • This cake will keep in the fridge for up to 5 days in a close-able container. If you double wrap with plastic and place in the freezer, it will keep for up to one month.
