This Conversation Heart Cake is the perfect thing for Valentine’s Day! It’s flavored with fresh or frozen strawberries and so fluffy and delicious!

Not going to lie to you, this is way less exciting than the Kim Kardashian chocolate conversation hearts that all the famous people on Instagram have been smashing. I want one!

This cake is still really amazing. It’s strawberry because we all know that conversation hearts are really gross. I bought a variety bag for this shoot (to use as props) and ate a few and omg they were so terrible!!

It reaffirmed my decision to make the cake a yummy strawberry cake. Remember when I made this strawberry sheet cake? It’s that recipe and made it into a two-layer heart cake. I topped it with strawberry frosting and a little message of LET’S GET COZY!!

It took me exactly a whole lot of hours and curse words to be able to write “LETS GET COZY” in buttercream. I will say that I can use some buttercream-writing-practice.

I was very close to taking it to the nearest grocery store where I was gonna plead with the woman who works at the bakery to write it for me. But then I thought, NO! This is a learning experience.

How to Make Strawberry Conversation Heart Cake

I wrote this out on parchment paper and transferred it to the freezer to firm up. I used a small offset to get it off of the parchment and then placed it on the cake.

This worked really well because I kept writing it kinda crooked and it aggravated me.

So, yeah, do it that way. Parchment and the freezer are your friend!

If you wanna make this cake for your friends and then smash it like one of those BAE hearts, then that is totally fine, just please send me photos via DM.

Oh and here’s a link to the heart pan that you can buy off Amazon.

And then here’s the one I purchased and used from Michael’s. I used my Michael’s coupon from their App and it ended up being about $4. Totally worth it. Lol.

This Conversation Heart Cake is the perfect thing for Valentine's Day! It's flavored with fresh or frozen strawberries and so fluffy and delicious!


Roasted Strawberries:

  • 1 1/2 cups from 1/2 pound sliced strawberries, (you can use frozen just be sure to thaw)
  • 2 tablespoon white granulated sugar

Strawberry Sheet Cake:

  • 2 3/4 cup cake flour, plus more for dusting pans
  • 2 1/2 teaspoons baking powder
  • 1 teaspoon kosher salt
  • 1 cups unsalted butter, at room temperature
  • 1 3/4 cups granulated sugar
  • 3/4 cup milk
  • 6 large egg whites
  • 2 teaspoons pure vanilla extract or 1/4 teaspoon vanilla paste

Strawberry Frosting:

  • 1 1/2 cups unsalted butter, at room temperature
  • 4 cups powdered sugar, sifted
  • 2 tablespoons strawberry puree, from above
  • 1 tablespoon heavy cream
  • Red food coloring, optional


To Make the Roasted Strawberries:

  • Preheat the oven to 350 degrees F. Add the sliced strawberries to a small baking dish and toss with the sugar. Transfer them to the oven to roast for 10 to 15 minutes.
  • Remove and allow them to cool for about 5 to 10 minutes. Add the strawberries to a blender and pulse until smooth. (You should end up with about 1/2 cup puree.) We’re going to use this for the cake and the frosting.

To Make the Cake:

  • Keep the oven at 350 degrees F (as it was for roasting the strawberries). And grease an 8-inch heart cake baking pan OR two regular 8-inch cake pan. Set aside.
  • In a medium bowl, add the flour, baking powder and salt. Whisk until combined. Set aside.
  • To the bowl of a stand-up mixer with the paddle attachment, add the butter and sugar. Beat until light and fluffy, about 2 to 3 minutes. In a measuring cup, pour in the milk, egg whites, vanilla extract or paste and reserved 1/4 cup strawberry puree (save the rest for the frosting) and whisk until combined.
  • Turn the mixer to low speed and, alternating between the dry ingredients and the liquid ingredients (the strawberry/egg white mixture), add the them butter/sugar mixture until the batter is relatively smooth. If you want to make it a bit more pink (it’ll probably be a light pink), add a drop of food coloring.
  • Pour the batter into the prepared baking pan and transfer to the oven to bake for 20 to 25 minutes, until a skewer inserted into the center comes out clean. OR, if you're using a single heart pan, add half of the batter to the pan. (We'll fill it up after we bake the first layer.)
  • *NOTE: You can buy two heart pans, but I bought one. So I baked this cake one layer at a time.
  • Allow the cake to cool in the pan for about 5 minutes and then invert onto a cooling rack and cool to room temperature. It’ll probably take a good hour. Repeat with the second layer, if needed.

To Make the Strawberry Frosting:

  • In the bowl of a stand-up mixer, with the paddle attachment, add the butter and powdered sugar; beat until smooth, about a minute. Pour in about 3 tablespoons of strawberry puree and heavy cream. Beat again until smooth and fluffy, about 2 minutes. If you like add a drop of food coloring to get that conversation-heart-color-pink.

To Decorate the Cake + To Make the Writing:

  • When the cake is completely cool, add some of the frosting on top of the cake. Using an offset spatula or any spatula you own, smooth it out until it reaches the edges. Add the second layer and continue decorating the cake.
  • You’ll have leftover frosting. Add a few drops of food coloring to it until it turns red. I needed about 3 drops. This will vary depending on what type of food coloring/gel you have. Transfer to a piping bag with a small round tip on the end.
  • On a piece of parchment, write out what you want to say. Try to make them as even as possible. Transfer to the freezer to chill for 10 minutes. With a small butter knife or offset spatula, remove them from the parchment paper. Place them on the cake and serve.

    Ughh. I wanted this to work so badly!!! I made it for a Valentines party and it was a total bust :(. The only redeeming quality was the frosting, which I 100% recommend trying. The part that threw it off was the cake being stodgy in a very bad way. Also I tasted the batter and it had a really amazing taste but when the cake was baked it didn’t retain any of the flavor. Maybe it’s something I did???

    Sadly this cake didn’t turn out great for me. I’m an experienced baker, but this recipe ended up rather dry and without great flavor. The saving grace is the strawberry frosting, which is delightful. However the cake was too dry and almost cornbread-like for my taste. I was missing the fat content and richness from the egg yolks.

  3. Okay so I think it was because i miss measured the strawberries and also did not mix the ingredients properly the cake turned okay tho it was much lighter in color than the one you made!!! I might try this recipie again when i have more time!!!

  4. Hi so i ve been trying to make this recipie since i saw it in February and finally today on april 8th at 10pm and now it’s almost 1 30am on april 9th and im crying!!! This is not your fault i misread your instructions a few times!!! This was not a good choice for someone who has never made a cake from scratch before!!! But im still hoping it turns out okay!!! It is a very cute cake!!! Thank you for the recipie!!!
