My niece turned five and asked for a cake that looked like a cartoon. I found myself staring at a box of fondant at midnight, wondering if I'd bitten off more than I could chew. The kitchen smelled like vanilla and butter, and I had red gel on my fingertips. When I finally placed those bright white fondant eyes onto the frosted surface, the whole cake came alive, and I couldn't stop grinning.

I made this for a retro-themed birthday, and the room went silent when I carried it in. Someone said it looked too good to eat, but within minutes, forks were clinking and frosting was disappearing. A friend who never bakes asked for the recipe on the spot. That moment reminded me why I love making cakes that tell a story before the first bite.

Ingredients

  • All-purpose flour: The foundation of your tender crumb, sifted once to avoid any lumps that can create dense pockets.
  • Granulated sugar: Creaming it with butter creates air pockets that make the cake light and fluffy.
  • Baking powder: Fresh baking powder is essential, check the expiration date or your layers may fall flat.
  • Salt: Just a pinch sharpens the sweetness and balances all the flavors.
  • Unsalted butter (for cake): Room temperature is key so it blends smoothly without leaving greasy streaks.
  • Large eggs: Let them sit out for thirty minutes so they incorporate evenly and don't shock the batter.
  • Whole milk: The fat content keeps the crumb moist and adds richness you can taste.
  • Vanilla extract: Pure extract gives a warm, rounded flavor that artificial versions can't match.
  • Red gel food coloring: Gel is more concentrated than liquid, so you get vibrant color without thinning the batter.
  • Cream cheese: Must be soft and smooth or you'll end up with lumps in your buttercream.
  • Unsalted butter (for buttercream): Again, room temperature ensures a silky, spreadable frosting.
  • Powdered sugar: Sift it to avoid gritty texture and achieve that cloud-like finish.
  • Black fondant: Pre-made fondant saves time and kneading effort, and the color stays true.
  • White fondant: Rolls out beautifully for eyes and accents, and takes edible dust well.
  • Red fondant: A small amount goes a long way for lips and decorative touches.
  • Edible pearl dust: Optional, but it adds a subtle shimmer that catches the light.
  • Cornstarch: Dusting your surface prevents fondant from sticking and tearing.

Prep the pans:
Preheat your oven to 350°F and grease two 8-inch round pans, then line the bottoms with parchment. This step prevents sticking and makes releasing the cakes effortless.
Mix the dry ingredients:
Whisk flour, baking powder, and salt together in a medium bowl. Set it aside so it's ready when you need it.
Cream butter and sugar:
Beat butter and sugar on medium speed for about three minutes until the mixture looks pale and fluffy. This incorporates air and sets up your cake's texture.
Add eggs and vanilla:
Drop in eggs one at a time, beating well after each, then stir in vanilla extract. Scrape down the sides so everything blends evenly.
Alternate wet and dry:
On low speed, add the flour mixture and milk in three parts, starting and ending with flour. This method keeps the batter tender and prevents overmixing.
Color the batter:
Stir in red gel food coloring until the batter is a deep, uniform red. Don't be shy with the color, it will lighten slightly as it bakes.
Fill and bake:
Divide the batter evenly between your prepared pans and smooth the tops with a spatula. Bake for 25 to 30 minutes, rotating halfway, until a toothpick comes out clean.
Cool completely:
Let cakes rest in the pans for ten minutes, then turn them out onto wire racks. They must be completely cool before frosting or the buttercream will melt.
Make the buttercream:
Beat cream cheese and butter together until smooth, about two minutes. Gradually add powdered sugar, one cup at a time, then beat on medium until light and fluffy.
Level and stack:
Trim the domed tops with a serrated knife so the layers sit flat. Spread buttercream on the first layer, then carefully place the second layer on top.
Crumb coat:
Apply a thin layer of buttercream all over the cake to seal in crumbs. Chill for twenty minutes until the frosting feels firm to the touch.
Final coat:
Spread a thicker layer of buttercream over the crumb coat and smooth it with a cake scraper or offset spatula. Take your time here for a clean canvas.
Roll the black fondant:
Dust your work surface with cornstarch and roll black fondant to about 1/8-inch thickness. Cut out Betty's hair silhouette using a template or freehand, then set it on parchment.
Shape eyes and lips:
Roll white fondant and cut two large circles for eyes and small hearts for highlights. Roll red fondant and cut out lips, then dust everything with pearl dust if you like.
Attach the hair:
Once the frosting is firm, gently drape the black fondant hair over the front of the cake. Trim any excess at the base and smooth it down carefully.
Add facial features:
Attach white eyes and red lips with a tiny dab of buttercream. Use extra black fondant to pipe or cut eyelashes and eyebrows, positioning them around the eyes.
Finish with details:
Roll a thin coil of red fondant into a headband and place it across the top edge of the hair. Add any final touches like sugar flowers or edible sparkles around the base.
Rest before serving:
Let the decorated cake sit at room temperature for thirty minutes so the fondant settles. This makes slicing cleaner and gives flavors time to meld.

The first time I served this cake, a little girl walked up and touched Betty's fondant hair, then looked at me with wide eyes and whispered, "She's real." That reaction made every late-night fondant struggle worth it. Cakes like this do more than satisfy a sweet tooth, they create memories that stick around long after the last crumb is gone.

How to Store Your Cake

I learned the hard way that fondant doesn't love the fridge. Condensation forms when you take it out, and the finish gets sticky and dull. If you must refrigerate, place the cake in a large box to protect it, and let it come to room temperature slowly before unveiling. For short-term storage, a cool room away from direct sunlight works perfectly and keeps the fondant looking sharp.

Flavor Variations to Try

One time I swapped the vanilla extract for almond, and the cake took on a subtle, sophisticated edge that adults loved. You can also fold in a teaspoon of cocoa powder and a splash of white vinegar to nudge this closer to classic red velvet territory. Swiss meringue buttercream instead of cream cheese gives you a lighter, silkier finish that pairs beautifully with fresh berries on the side.

Troubleshooting Common Issues

If your cake dome cracks or sinks, check your oven temperature with a separate thermometer because ovens lie. Fondant that tears usually means it was rolled too thin or the surface wasn't dusted enough with cornstarch. When buttercream looks curdled, it's often a temperature issue, let it come to room temperature and beat it again until it smooths out.

  • Always rotate your pans halfway through baking for even color and rise.
  • Use wooden dowels through the layers if you're stacking more than two tiers for stability.
  • Prepare fondant decorations a day ahead and store them in an airtight container at room temperature.

Recipe FAQs

How far in advance can I prepare the fondant decorations?

Fondant decorations can be made up to two days ahead and stored in an airtight container at room temperature. Keep them away from humidity to prevent softening or sticking.

Can I make this as a single layer cake instead?

Yes, you can bake the batter in a single 9-inch round pan. Increase the baking time to 35-40 minutes and adjust the decorating proportions accordingly for a smaller canvas.

What's the best way to achieve deep red color?

Use gel food coloring rather than liquid for the most vibrant red without altering the batter consistency. Start with one tablespoon and add more as needed for your desired shade.

How do I prevent the fondant from sagging on the buttercream?

Apply a thin crumb coat and chill the cake for at least 20 minutes until the frosting is firm to the touch before placing fondant decorations. This creates a stable surface.

Can I freeze the unfrosted layers?

Wrap cooled layers tightly in plastic wrap and freeze for up to three months. Thaw overnight in the refrigerator before bringing to room temperature and decorating.
