How to Make a Heart Cake




About: I work at instructables by day, and turn into a stitch witch by night. follow me on instagram @jessyratfink to see what i'm working on! ^_^

Heart cakes are amazingly easy to make and super cute! In this instructable I'll show you the easiest way to make a heart cake - all you need are two cake pans (one round and one square) of the same size.

Step 1: Ingredients + Tools


  • box of cake mix + ingredients needed to make it OR homemade cake batter recipe that can fill a 9x13 pan
  • frosting
  • sprinkles
  • maraschino cherries


I cheated and went with a boxed cake mix and jarred frosting since I was feeling lazy. :P

Step 2: Prepare the Batter

I always like to add extra mix-ins to boxed cake mix - just makes it taste a little better!

In this case I used a whole 12 oz jar or maraschino cherries. I drained them (and squeezed out as much liquid as I could) and then chopped them finely. I then rolled them in flour before adding them to the batter - just to keep them from all dropping to the bottom.

Step 3: Bake the Cakes!

Grease your pans and line the bottoms with parchment for easy removal. Pour in the batter - try to eyeball it and divide it evenly.

I baked these for about 30 minutes, and then set them on wire racks to cool.

You really want the cakes to be nice and cool to the touch before frosting!

Step 4: Color the Frosting

I used 1 1/2 jars of frosting and about 20 drops of red food coloring to get this pink color.

Step 5: Trim and Assemble the Cake

I like to trim off the very edges of the cakes - you get a more even surface that way since the edges tend to bake up thinner.

Cut the round cake in half and check the fit with the square one - take off corners as necessary for a nice look!

Step 6: Frost!

Use a small bit of the frosting on the edges to glue the round halves and square cake together.

You'll want to start by applying frosting over the seams - you might need a little more frosting here than anywhere else if there's a difference in height.

Then you can frost as normal and decorate. I decided to cover mine entirely in sprinkles once my plan to write with sprinkles failed. ;)
