This keto cake is the best way to celebrate any special occasion. Instead of looking for a sugar free birthday cake or ice cream, why not combine the two and make a decadent ice cream cake!
With both homemade layers and store-bought layers, this cake is simple but still impressive. The keto cake and ice cream are store-bought while the mocha whipped topping is made fresh. Although you could make your own keto chocolate ice cream if you really want to go all out!
This keto ice cream cake has layers of fluffy sugar free cake, keto chocolate ice cream and a creamy whipped topping with a special raw cacao powder twist that gives incredible flavor.
How to make keto ice cream cake
- Make your favorite low-carb cake. I prefer to use boxed keto cake mix to prepare the cake. This is a quick, easy way to get a delicious cake with minimal effort.
- Make a chocolate whipped cream.
- Layer your cake with slices of keto cake, ice cream and whipped topping. Repeat the layers until the cake is used up.

Ingredients
keto cake, prepared to package directions -
2 cups heavy whipping cream
-
2 tablespoons powdered sugar free sweetener
-
2 tablespoons unsweetened cocoa powder
-
1 1/2 pints keto ice cream
-
loaf pan
Step by Step Instructions
-
Bake cake
Put ice cream in the refrigerator 2-3 hours prior to assembling the ice cream cake. This will make the ice cream easier to spread. Mix and bake cake in a square baking dish according to package directions. Let cool on a wire rack before slicing.
Quick Tip
If you forget to do this step or don't have time, you can carefully defrost the ice cream in your microwave until it's a spreadable consistency, but not liquidy. -
Make whipped topping
In a large bowl, add whipping cream, powdered sugar free sweetener and unsweetened cocoa powder. Beat on medium speed until frothy. Then increase speed to high and continue beating until stiff peaks form.
-
Cut the cake
Cut cake in half like slicing through a hamburger bun.
Quick Tip
Make sure cake is cool in the center before assembling. -
Cake layer
Line a loaf pan with parchment paper or plastic wrap. Cut cake into pieces to form a single layer in the loaf pan.
-
Ice cream layer
Spread a thick layer of ice cream on top the cake.
-
Whipped cream layer
Spread a thick layer of whipped cream on top the ice cream. Repeat the layers one more time finishing with cake and a thin layer of whipped cream.
-
Freeze
Freeze the cake in the freezer for at least 6-8 hours or overnight.
-
Finish decorating
Add a final layer of whipped topping to the top and around the sides of the cake. Freeze for 10-20 more minutes to set the cake before slicing and serving.
I made this keto ice cream cake for a summer get-together and it came out better than I expected. The ice cream layer was super easy to spread after letting it sit as recommended and it didn’t melt too fast while assembling. What stood out the most was how well the flavors came together after freezing overnight. Everyone was surprised it was low carb.
