Ingredients
Below is everything you’ll need to make this Funfetti ice cream cake. This includes the components for the homemade whipped cream and the rainbow sprinkles for decoration!

- Funfetti cake: Grab whatever ingredients are listed on the box as well. Prepare the cake according to the instructions in two 8-inch cake pans. Ensure the cakes are completely cooled before working on your homemade ice cream cake.
- Vanilla ice cream: Use whatever brand and variety of vanilla ice cream you want for this recipe. French vanilla and vanilla bean work great, too.
- Heavy cream: I like to make homemade whipped cream to frost the outside of the cake. It holds up well in the freezer and doesn’t make for an overly sweet bite. Ensure the cream is cold for it to whip the best.
- Sugar: I add just a little sugar to sweeten the cream, but not too much to overpower the other flavors of this birthday cake with ice cream.
- Vanilla extract: The subtle vanilla flavor in the cream takes the frosting for the ice cream cake to the next level. It adds flavor without more sweetness.
- Rainbow sprinkles: Finish your cake with rainbow sprinkles! It reinforces the Funfetti theme, making it the perfect garnish.

Variations
- Chocolate Ice Cream: Swap the vanilla ice cream for chocolate ice cream for a rich twist.
- French vanilla cake: Make a French vanilla cake instead of Funfetti to create a vanilla flavor explosion!
- Add fresh fruit: Garnish the finished cake with fresh fruit like strawberries and blueberries for more color right before serving.
How to Make an Ice Cream Birthday Cake
To get started on this birthday ice cream cake recipe, you will need to grab two 8-inch cake pans and prepare and bake your Funfetti cakes according to the package directions. While they’re cooling, you can work on the next step!

Step 1: Make the whipped cream. Combine the heavy cream, sugar, and vanilla in a large mixing bowl and whip it until there are stiff peaks.

Step 2: Add a layer to the pan. Grab a springform cheesecake pan and place a piece of parchment on the bottom. Then, spread a layer of the creamy whipped cream first.

Step 3: Top with cake and ice cream. Add a layer of cake and top it with the softened vanilla ice cream. Smooth it out well to cover the cake.

Step 4: Add the second cake layer and whipped cream. Add the final cake layer on top of the ice cream, and then spread a thick layer of whipped cream on top.

Step 5: Freeze and remove from the pan. Pop your cake into the freezer for at least 6 hours or overnight if possible. Then, flip the pan onto a cake stand and carefully remove the cake from it.

Step 6: Finish decorating and serve. Garnish the Funfetti ice cream cake with rainbow sprinkles and whatever decorations you want before serving.
Recipe Tips
- Soften the ice cream ahead: Pull your carton of vanilla ice cream out of the freezer about 15 minutes before you plan to use it. You want it to be softened but not soupy.
- Get it in the freezer quickly: Stick the ice cream cake into the freezer ASAP once it’s assembled! It will start melting quickly.
- Use Cool Whip: Skip the homemade whipped cream and finish the cake with a layer of Cool Whip to save time.

- Make Ahead: You may prepare the cake up to 3 days in advance and keep it in the freezer. This is ideal for a birthday party or special occasion, so it’s perfectly firm and ready to eat.
Serving Suggestions
- Make this happy birthday ice cream cake extra special with spring Rolo bites as a sweet and salty garnish. Add them right before serving!
- Add a layer of spicy strawberry jam for a fruity twist with a spicy kick.
- Serve this ice cream cake for a summer event and add these patriotic fruit kabobs on the side or top. Create the ultimate birthday experience and make a homemade pizza like a tortilla pizza or double cheeseburger pizza for lunch or dinner, and enjoy a slice of ice cream cake with sprinkles for dessert.

Recipe FAQs
A sharp knife or cake leveler will do the trick here! Shave off a small slice of the top to make the cake layers flatter and even.
Sure! A naked Funfetti ice cream is delicious, too. It’s a lovely, rustic way to serve it!
Run the knife under hot water for a few seconds to warm the blade. This will give you cleaner and more even slices.
