How to Make a Heart Cake
From start to finish, this adorable heart cake takes about 1 hour. I LOVE easy dessert recipes like this! Watch how easy it is to make a heart shaped cake:
How to Make a Heart Cake
Prepare the square and circle cake pans with non-stick spray
Gather all of the ingredients according to your cake mix of choice (or make a homemade recipe!)
Mix all of the ingredients until smooth
Pour 1/2 of the cake batter into the square pan and 1/2 into the circle pan. Eye ball the cake batter to make sure the thickness of it in each pan looks similar.
Bake the cakes according to the cake mix recipe
Remove the cakes from their pans
Cut the circle cake in half evenly.
Position the square cake so it looks like a diamond, then place each half of the circle cake like this:
Place the cake on a large plate or cake board. If you don’t have one, use wax paper or parchment paper and place the cake where you plan to serve it.
Liberally apply the frosting. It’s so easy! The frosting will fill in the imperfections and it will connect the 3 pieces like magic!
Add sprinkles, icing letters, birthday candles, whatever you want:)
Isn’t that adorable and easy?
Make a heart shaped cake for Valentine’s Day, a birthday, or a special gathering. People will be so impressed (plus it tastes so good too!).
