About these cakes for Valentine's Day
- The Cake Shape - Instead of using a heart pan I used a sheet cake. I made two heart cakes.
- If you do not have a heart cake pan you can just print the image of the heart you want from the internet. Cut out the shape as use it as your guide.
- Cake Flavor - This cake is my vanilla cream cake (recipe below) baked in a sheet pan but you can certainly use any other firm butter-based cake from my over 50 cake recipes. Often a pound cake or sponge cake works better for carving.
- Frosting - I've used my Velvet American Buttercream but ganache would work just as well.
- Fondant - This is my Homemade Sugar paste /Fondant Recipe. You can also use my quick and easy marshmallow fondant. You can also try any of my other frostings recipes. See 30 plus frosting recipes here
When should I decorate my cakes
Timeline for decorating cakes - The active time on this cake is close to two hours but this does not include the negative time you need in between. This also does not include time for making homemade fondant which would be another 10 mins + 3 hours chilling.
- Bake the sheet cake - 35 mins (10 mins prep - 25 mins baking)
- Frosting - 5 minutes
- Chill the cake - 2 hours at least (negative time)
- Carve and crumb coat - 30 mins
- Chill the cake - 15 mins (negative time)
- Smoothing - 20 mins
- Chill the cakes - 1 hour (negative time)
- Fondant work - 30 mins
- Embossing - 20 mins

Step by step instructions (pin)
Bake the cake
- Preheat the oven to 160 C/320 F.
- Grease and line one 7-inch heart cake pan or 8 x 8-inch square pan
- Sift flour with baking powder and salt.
- Cream butter and sugar until light and fluffy
- Add eggs one at a time.
- Followed by the vanilla extract.
- Lastly, add flour mixture and cream.
- Bake for about 25 to 30 minutes until a skewer inserted in the center comes out clean.
- Cool on a wire rack for 10 minutes before removing from the pan.
- Always cool cakes completely before you decorate or store cakes away
- Freeze the cake for an hour (optional) as it makes it easier to carve.
Prepare the frosting
- Cream butter for a minute
- Add vanilla and whipping cream - whip some more
- Add the powdered sugar - one cup at a time
- Once all the powdered sugar is in - whip for three minutes until the buttercream is light and fluffy.
Carve the cakes
- If you bake a sheet pan like me - Using the heart template, cut out the heart cakes. Hold the knife at a 90% angle - straight up - so you get a nice straight side (not beveled)
- Simple syrup the cakes (optional)
- Crumb coat the cakes and let chill for 15 minutes
- Add a second coat of buttercream and smooth as much as you can, using a spatula and scraper.
- I like to use a cling wrap over the chilled cake and use my hand to create a smooth surface.
- Chill the cake for at least an hour.
Cover with fondant
- Roll red color fondant larger than the diameter of the cake.
- Place it on the cake and smooth it out. Cut any excess as necessary.
- Use a fondant smoother or your hands to smooth the sides and edges.
Emboss the words
- As you can see I have used plastic alphabets to emboss into the fondant. I then painted those in different colors.
- If you don't have these alphabet cutters, you can simply use a paintbrush and edible gel food colors and write the words freehand. It sounds scary but it's not as hard as it sounds. Use single strokes as shown in the video below.
