Rice Krispies Birthday Cake

I'm kind of obsessed with the birthday cake trend that's been all over social media e-v-e-r-y-w-h-e-r-e.  Who doesn't love birthday cake?  Who doesn't love rice krispie treats?  If you answered "not me" to either of those questions then we can't be friends.  Sorry, but I've drawn the line in the sand.

Now, if you're still reading this then we're clearly meant to be friends.  Yay!  Weeks ago, on the heels of my favorite funfetti popcorn, I was mulling over a clever treat combination that had not already been done a million times over. Birthday cake rice krispie treats may not be an original, but have you ever seen it shaped like a cake??

The trickiest thing about rice krispie treats is mushing the mixture into your pan before it all cools and not ending up with half of it on your spoon.  With this recipe you've got to finish mixing, add your sprinkles and then mash it all into the metal can all before it becomes hard.  I have confidence that if you want it bad enough, you can make this sweet dream come true!


  • 6 tablespoons butter
  • 1 10 oz. package of mini marshmallows (plus an extra handful because I like mine gooey)
  • 6 cups of rice krispies
  • 3/4 cup dry, birthday cake mix
  • sprinkles, as many as your heart desires


Find a can in the back of your cabinet, covered in dust.  I'm going to guess it's something gross like green beans or beets.  Empty the contents, wash and dry the inside of the can, then spray generously with cooking spray.  Also prepare a small dish for the leftovers.  Melt all the butter in your stock pot.  Once the butter has melted quickly add the cake mix and marshmallows.  Stir the ingredients until smooth, then add your cereal and sprinkles.  Mix quickly to coat the rice krispies and then spoon into the can.  Then spread out the remaining mixture in the small pan you previously prepared.

I waited about an hour to make sure my cake was cool and solid.  Then I used my can opener to unseal the other end and pop my cake out.

For the frosting I mixed about two tablespoons of butter with a couple spoonfuls of powdered sugar - whatever tastes good to you.  With a knife spread the frosting on top of your cake and then dip in in a bowl of sprinkles!  Pop in a candle and your rice krispie birthday cake is done!
