Quadruple Chocolate Birthday Cake will satisfy any serious chocolate craving without becoming overwhelmingly sweet. This cake is one of the most requested birthday desserts in my house.
Quadruple Chocolate Birthday Cake
This recipe yields a generous amount: three 8-inch cake layers, about two dozen regular cupcakes, and several jumbo muffins. It’s perfect for a large gathering, a party plus extras for school or work, or anytime you want to have leftovers—because with this cake, you’ll want them.
I keep the decoration simple because I’m not a skilled cake decorator. If piping is not your forte either, this cake is forgiving: it’s easy to assemble and looks impressive on the table without elaborate techniques.
The cake combines chocolate Ovaltine in the batter, a whipped dark chocolate ganache between the layers, a chocolate Ovaltine buttercream on the outside, caramel-filled chocolate chips, and extra ganache dripped over the top. A scattering of chocolate sprinkles finishes it off.
If you want a number on top, press a spoon or butter knife into the frosting to create a shallow depression in the shape you want, chill the cake for about 30 minutes to firm the frosting, then pour ganache into the impression. Add more sprinkles and you’re done. I didn’t crumb coat this particular cake because it didn’t produce many crumbs, but use your judgment—crumb coating is helpful if your layers are crumbly.
For cupcakes I used a large star tip and piped a thick swirl of frosting, then drizzled ganache on top and added sprinkles.

How To Make This Recipe
The overview below outlines the process. Use the full recipe card at the bottom for exact measures and timing.
- Mix the batter – Sift dry ingredients together. In a mixer combine oil, hot coffee, half-and-half, and sour cream, then slowly add the dry mix. Mix in vanilla and eggs just until combined.
- Prepare pans and bake – Spray three 8-inch cake pans, line with parchment, and lightly spray again. If making cupcakes, line tins. Fill pans and liners about two-thirds full and bake until a toothpick comes out clean.
- Cool completely – Let cakes rest in pans for 15 minutes, then transfer to wire racks to cool fully before frosting.
- Make frosting and ganache – Beat butter smooth, sift and add cocoa and powdered sugar, then incorporate dissolved Ovaltine mixed with heavy cream until light. For ganache, heat cream and butter, pour over chocolate chips, stir until smooth, and add vanilla. Chill and whip most of the ganache for the filling.
- Assemble and decorate – Spread whipped ganache between layers, frost the outside, chill briefly, then drizzle remaining ganache over the top and edges. Add sprinkles, caramel-filled chips, and pipe frosting on cupcakes as desired.
Recipe FAQ
Store the cake covered in the refrigerator if your kitchen is warm or if the ganache is very soft. For the best texture, let slices sit at room temperature for 20–30 minutes before serving. Cupcakes keep well in an airtight container in the fridge.
This cake is best served at room temperature. If chilled, let slices sit out for 20–30 minutes. A few seconds in the microwave will warm a slice slightly, but avoid overheating to prevent the frosting from melting.
Yes. The layers can be baked a day ahead and wrapped tightly once cooled. Frosting and ganache can also be prepared in advance; bring them to a spreadable consistency before assembly. You can fully assemble the cake the day before and keep it chilled.
Yes. The batter is great for cupcakes. Fill liners about two-thirds full and bake until a toothpick comes out clean—typically 13–15 minutes.
Yes. Swap canola oil for another neutral oil, use whole milk plus a splash of cream instead of half-and-half, or use semi-sweet chocolate chips for a less sweet ganache. If you use salted butter, reduce or omit added salt in the frosting.
2026 update: I removed many of the older personal stories from past posts to keep them focused, but this one includes a few family memories I’m keeping for posterity. The child in these photos has grown a lot since then, and I’m leaving this here for the memories.
We recently wrapped up the last birthday party of the summer and also started a new school year, which left the house unexpectedly quiet with all four kids in school for the day. The quiet was a nice change of pace—plenty of time to work and, yes, I may have left the TV on for background noise. The cake was an easy winner for our chocolate-loving birthday boy.
Seven is a special age—right on the edge between little and big, full of discovery and growth. Every birthday our family holds a friendly present competition, and this year Grandpa and Grandma won with a jersey that made the birthday boy very happy.
Another standout gift has provided hours of playtime for all the boys—more batting practice in our future, for sure.
Happy birthday to my third son—may the next year be full of learning, laughter, and love. Stay little a bit longer, please.

Instructions
Cake:
- Sift together dry ingredients and set aside. In a mixer, combine canola oil, hot coffee, half-and-half, and sour cream. Mix on low for 30 seconds. Slowly add the dry mixture and mix on low until incorporated. Add vanilla, then add eggs one at a time, mixing just until combined.
- Prepare three 8-inch cake pans by spraying with baking spray and lining the bottoms with parchment circles. Lightly spray the parchment. Line cupcake tins with paper liners and lightly spray.
- Pour batter into pans and cupcake liners about two-thirds full.
- Bake at 350°F: cupcakes for about 13–15 minutes, cake layers for about 25–30 minutes. Use the toothpick test to confirm doneness.
- Let cakes and cupcakes cool in pans for 15 minutes, then transfer to wire racks to cool completely before frosting.
Frosting:
- Beat room-temperature butter until smooth.
- Sift in cocoa powder and powdered sugar, mixing to avoid lumps. Add vanilla and mix.
- In a separate bowl dissolve Ovaltine in heavy cream, then slowly add to the butter mixture. Beat on high 1–2 minutes until the frosting lightens and becomes fluffy, scraping the bowl as needed.
Ganache:
- Heat heavy cream and butter until almost boiling. Pour over chocolate chips in a metal bowl and stir until the chocolate is fully melted. Stir in vanilla.
- Cool the ganache and whip about two-thirds of it for the cake filling. Leave the remaining third at room temperature for drizzling.
For Decorating:
- Spread whipped ganache between cake layers. Ice the cake with the Ovaltine buttercream. If adding a number, press a shallow depression in the top, then chill the cake for 30–40 minutes. Pipe frosting onto cupcakes with a large star tip.
- Drizzle room-temperature ganache over the edges to create drips. Fill the top depression with ganache without overflowing, using a toothpick to guide it. Add sprinkles and caramel-filled chips to finish.
