How to Make a Giant Conversation Heart Cake for Valentine's Day

Sharing the love has never been cuter!

Not everyone is a fan of conversation hearts: In a recent poll, more than two-thirds of Food Network fans said they don’t eat them. But this heart is different — it’s a giant cake! To create the supersize sweet, Food Network Magazine turned two cakes into a heart shape, then covered the whole thing in a homemade marshmallow fondant. For the message, you just need food coloring...and something sweet to say!

Get the Recipe: Conversation Heart Cake

Step One:

Preheat the oven to 350 F. Coat a 9-inch round and a 9-inch square cake pan
(2 inches deep) with cooking spray. Prepare the cake mixes as directed; divide between the pans. Bake until a toothpick comes out clean, 30 to 35 minutes.

Step Two:

Let the cakes cool, then remove from the pans. Trim the tops of the cakes with a long serrated knife to make them level. Cut the round cake in half as shown.

Step Three:

Working on a cake board (you can cut the board into a heart shape to fit the cake) or a cutting board, position the 2 half circles of cake against 2 sides of the square cake to make a heart.

Step Four:

Cover the cake with the white frosting, using the frosting to fill in any gaps between the cakes.

Step Five:

Combine the marshmallows and water in a large microwave-safe bowl. Microwave, stirring with a rubber spatula, until melted and smooth, 1 to 2 minutes. Add the green food coloring and stir until smooth.

Step Six:

Transfer the marshmallow mixture to a stand mixer. Gradually add all but 1/2 cup of the confectioners’ sugar and beat until combined. Beat in the butter.

Step Seven:

Scrape the marshmallow fondant onto a sheet of parchment and knead in confectioners’ sugar until it’s no longer sticky. Dust the parchment with more sugar; roll out the fondant until it’s large enough to cover the cake, at least 13 by 16 inches.

Step Eight:

Carefully flip the parchment and fondant onto the cake; peel off the parchment. Gently press the fondant against the sides of the cake and smooth with your hands; trim the excess. Brush off the extra sugar.

Step Nine:

Use the wide end of a chopstick to press letters into the fondant (it’s best to do this before the fondant dries out). Use a small brush to paint hot pink or red food coloring in the letter indentations.
