Making this heart shaped cake is so much fun, especially if you have kids in the house. In this post, I’ll show you how to make a heart shaped cake, using only one circle and one square cake pan, with a downloadable PDF (this is a great cooking with kids activity).
To make this cake, you can choose to go the fully homemade route or not – both are delicious. Any box cake mix will work or any homemade cake recipe. Same with the frosting; it can be homemade or store bought.

How do you make a heart shaped cake?
- Spray square and circle cake pans with cooking spray.
- Line round cake pan with parchment paper. I do this by setting the cake pan on a piece of parchment paper and tracing it with a pen, then cutting out the circle.
- Spray parchment paper with cooking spray.
- Preheat oven to 350.
- Make cake batter.
- Divide batter evenly between square and round baking dishes.
- Bake until done. While cake is baking, make the frosting.
- Remove from oven and allow to cool completely on a wire cooling rack.
- Cut the circle down the middle.
- Put the square cake on a plate, diagonally, and then add the 1/2 circles to form the heart.
- Frost the cake and decorate. Enjoy!

When I made this cake, I used this chocolate cake recipe. It’s a basic cake recipe and it’s so delicious!
Then, for the frosting, I used equal parts heavy cream/whipped cream and confectioners sugar (1 1/2 cups heavy cream and 1 1/2 cups powdered sugar). Or you can always buy any pre-made frosting.

To decorate the cake, have some fun! I just used some simple natural sprinkles but get as creative as you’d like. I thought these edible stars looked fun or even any fun sprinkle mix like these.

This cake is seriously so easy to put together and would be perfect for celebrating a loved one’s birthday, Valentine’s Day or anytime you want to make someone feel special!

And as you can tell, the kids simply couldn’t keep their hands off of it! So, kid (and parent) approved ✔️
I hope this post showing you how to make a heart shaped cake makes you want to have some fun in the kitchen soon!

I don’t really have a “go-to” Valentine’s treat that I make; I love to mix it up! I made a heart shaped chocolate cake one year, and this year I made creme brûlée just for me and my husband for after the kids went to bed. I don’t have a hand held kitchen torch, so I just used the broiler in my oven. Added some strawberry slices to the top. It was fantastic!
Sweetphi says
That creme brulee you made sounds delicious!!

I have a heart shaped pan from my mom. Has to be well over 50 years old. I pull it out for Valentine’s Day and make a chocolate cake. Still makes me feel close to her and she’s been gone 34 years. Precious memories
Sweetphi says
Aw, that’s such a sweet memory!
Jennifer Joyce says
I have a strawberry cake recipe that is my family’s favorite. Since it’s red, they always expect it for Valentines and Christmas!
Sweetphi says
Oh that sounds lovely!

Sweetphi says
Cupcakes are always amazing too 🙂
Kim Henrichs says
A flourless chocolate cake is my go-to!
Sweetphi says
Oh yum, i love a good flourless chocolate cake too – I always order them if they’re on a restaurant menu!
KristyB says
This cake is so cute! However, I think I’m going to borrow the idea from another comment about heart-shaped brownies. That feels more my speed/energy-levels this year. 🙂
Sweetphi says
I love that you got ideas from the comment section – I too love the idea of heart-shaped brownies, they sound cute and easy!
Susan P. says
I love this heart shaped cake idea – especially for Valentine’s Day!

It’s such a cute and fun treat to have for Valentines day!
Amy Cooley says
My favorite Valentine’s Day treat would be an iced sugar cookie ( soft, not crunchy!).
Sweetphi says
Oh yum, nothing better than soft iced sugar cookies!
Cheri Scott says
Made this heart cake following the directions with a chocolate cake and your vanilla icing with sprinkles for family birthdays in February dinner. It went together like a charm and was so cute. The kids loved it as well as the adults. Plus it’s large enough for all our February birthdays I didn’t have to make a sheet cake! It’s adorable and so easy!
Sweetphi says
Oh I’m so happy to hear this, thank you so much for sharing this feedback, glad you all love it!! Happy birthdays!!

I remember my mom making heart shaped cakes when I was little. What a nifty idea. We loved the Valentine cakes – she would decorate them like a conversation heart.

I love that she decorated them with conversation hearts, how cute! Thank you for commenting!

I like a good cake especially one like this any day. But chocolate truffles win me over every time!

Oh yum, those are always delicious!

This is a great idea! My favorite thing to make for Valentines Day is maraschino cherry cake with cherry icing. It’s pink, tasty, and could be made in the shape of a heart like this.
Sweetphi says
Ooooo maraschino cake sounds amazing, i’m totally going to have to try that!
