Layers
The cake layers are soft and moist thanks to the combination of butter and a bit of oil, and the tangy note from buttermilk. Using both butter and oil gives the best balance of flavor and texture. The method is straightforward: cream the fats and sugar, add the wet ingredients, then fold in the dry ingredients and bake.
How to make a heart shaped cake from a round pan
Turn a round cake into a heart with a couple of simple cuts. Stack your filled layers, then cut a V into one side of the cake to form the point at the bottom of the heart. Use the two semicircular pieces you removed to create the rounded top of the heart, attaching them to the top edge. Trim as needed, give the cake a thin crumb coat to secure everything, then finish with a final layer of colored frosting.
Writing
Have fun writing messages on your mini conversation hearts. Ideas include:
- I ❤️ you
- Cutie
- DM me
- Kiss me
- Crazy 4 U
- Me + you
- BFF
- Be mine
For a playful twist, try anti-conversation heart messages like:
- I tolerate you
- Eww
- Bye
- Bite me
- Yeah right
Perfectly pipeable cream cheese frosting
This frosting is creamy and stable when the butter is soft (not melted) and the cream cheese is slightly softened. That balance helps the frosting hold its shape without needing excessive powdered sugar. Finish by adding heavy whipping cream a tablespoon at a time to achieve a light, airy texture. Avoid using milk, which can thin the frosting too much.
Why is my cream cheese frosting grainy?
Graininess usually means the butter was too cold when mixed. The butter should be soft enough to press an indentation easily but not greasy. If the frosting is grainy or uneven, warm a small portion (¼ cup) briefly and beat it back into the frosting until smooth, or add powdered sugar a quarter cup at a time to improve texture.
How to get perfect layers
Bring ingredients to room temperature so they combine smoothly and produce an even crumb. Weigh flour for the most consistent results; if using measuring cups, spoon the flour into the cup and level it off without packing. Watch your oven and test with a toothpick — the cake is done when it comes out clean.
Key ingredients
Full ingredient amounts and step-by-step instructions are in the recipe card below. These notes highlight tips for success.
Butter: Use a good-quality real butter. Salted butter can be used in the cake if you omit added salt.
Buttermilk: Store-bought buttermilk or kefir gives the best classic red velvet tang.
Food coloring: Gel food coloring produces the brightest red; natural powdered colors also work.
All-purpose flour: Weigh for accuracy or spoon and level when measuring by cup.
Cocoa powder: Both natural and Dutch-processed work; Dutch-processed gives a deeper color.
Cream cheese: Use full-fat brick-style cream cheese for a thick, stable frosting.
Heavy whipping cream: Use cream with at least 32% milk fat to keep the frosting light without becoming watery.
Step by step – layers
Step 1 — Prep: Preheat the oven to 355°F (180°C). Grease three 4″ pans with cold butter and line the bottoms with parchment.
Step 2 — Cream fats and sugar: Beat together butter, oil, sugar, and salt until light and fluffy, scraping the bowl halfway through.
Step 3 — Wet ingredients: Add eggs one at a time, then add buttermilk, vanilla, and red gel food coloring (add a little at a time until you reach the desired color). Some separation is okay.
Step 4 — Dry ingredients: Sift in flour, cocoa powder, baking powder, and baking soda. Stir until the batter is smooth and well combined.
Step 5 — Bake: Divide the batter among the pans, smooth the tops, and bake 22–30 minutes, or until a toothpick comes out clean. Cool in the pans for 10 minutes, then invert onto a rack to cool completely.
Step by step – frosting
Step 1 — Beat butter and sugar: Using a stand mixer with a paddle attachment or a large bowl, beat the butter and powdered sugar (start with 4 cups) until very light and fluffy, about 7–10 minutes, scraping the bowl occasionally.
Step 2 — Add vanilla and cream cheese: Add vanilla, then add the cream cheese a tablespoon at a time, beating well after each addition and scraping the bowl to ensure even mixing.
Step 3 — Finish the frosting: Add heavy cream one tablespoon at a time until the frosting is light and spreadable. Fold with a spatula to remove large air bubbles for a smooth finish.
Step by step – assembly
Step 1 — Trim: If the cake tops are domed, trim them and slice each layer in half horizontally.
Step 2 — Fill and shape: Spread a few tablespoons of frosting between the layers. Make two cuts on one side of the cake to form a V for the bottom point. Use the cut semicircles to build the rounded top of the heart.
Step 3 — Crumb coat: Apply a thin layer of frosting to seal crumbs and chill in the freezer for 10 minutes to set. Repeat for the remaining cakes.
Step 4 — Prepare colored frostings: Reserve about 4 tablespoons of frosting and tint it red for writing. Divide the rest into three portions and color them pink, yellow, and green (or your preferred palette).
Step 5 — Final frost: Apply a final layer of frosting to chilled cakes. For an extra-smooth finish, warm a metal spatula and lightly smooth the sides and tops.
Step 6 — Write messages: Pipe messages on each heart using the red-tinted frosting. Let cakes come to room temperature before serving for the best texture.
FAQ
Yes. Bake all the batter in a 9″ x 12″ sheet pan, cool, and cut out six hearts with a cookie cutter or knife. Use two hearts per mini cake to make three cakes total.
Yes. A 6″ round pan that’s at least 3″ deep works well. After baking, slice into layers, shape into a heart, and decorate as directed.
Chill the frosting for 10–15 minutes, then rebeat. Add powdered sugar a quarter cup at a time to thicken if needed.
Liquid food coloring can thin frosting and produce weaker color. Gel food coloring is recommended for bright, stable colors.

Notes
The frosted cakes will keep in the fridge in a covered container for up to 4 days. Bring to room temperature before serving so the frosting and cake soften.
Make Ahead
Cake layers can be baked a day ahead. Keep them in their pans covered with plastic wrap at room temperature. Make the frosting the day you plan to decorate for the best texture. Decorated cakes can be stored for up to 3 days for best freshness.
