Surprise your loved one this Valentine's Day or Mother's Day with a beautiful heart-shaped cake without having to buy a special pan. Made simply by combining cakes from a square pan and a circle pan, this easy, foolproof method gets you a perfect heart shape every time. No rulers or special equipment required!


  • Any cake recipe such as my chocolate sweet potato cake (double the ingredients for this recipe)
  • 1 8x8 square cake pan
  • 1 8-inch round pan
  • Any frosting (I doubled my vegan cream cheese frosting recipe and added a small cooked beet to color it pink. See more frosting options in the notes below).


  1. Bake a cake in each pan. If the recipe is for a two-layer cake, make one layer in a square pan and the other in a circle pan. Otherwise, double the ingredients to make a cake in each pan.
  2. Once the cakes have fully cooled to room temperature, cut the round cake in half and arrange the two semi-circles next to adjacent edges of the square cake to form a heart shape (see photos in the post above). 
  3. Use frosting to cover the entire cake so it becomes a single cake in the shape of a heart. Decorate with dye-free sprinkles or mini chocolate chips if desired.


The square pan must be the same size as the diameter of the circle pan for this method to work.

Cooking time below is based on the recipe I linked in the ingredients (chocolate sweet potato cake).  Adjust baking time based on the recipe you are using.  

If you are using a two-tier cake recipe then divide the tiers between the two pans. If you are using a single-layer cake recipe then double the recipe and put half of the batter in each pan.
