Sugar-Free Strawberry Layer Cake with Cream Cheese Frosting

A lighter version of classic strawberry cake featuring sugar-free strawberry jam and gelatin for intense berry flavor without excess sugar. The moist white cake layers are infused with pureed fresh strawberries and topped with tangy reduced-fat cream cheese frosting. Perfect for birthdays, spring gatherings, or when you want to indulge without the guilt. The combination of fresh strawberries in both the batter and frosting creates layers of strawberry taste, while the reduced-fat ingredients keep it on the lighter side without sacrificing the rich, satisfying texture expected from a proper layer cake.

Tips

Tip 1

Make sure cream cheese and butter are at proper temperature for smooth frosting - too cold will create lumps while too warm will make frosting runny.

Tip 2

Line cake pans with wax paper and spray again to prevent sticking, as the sugar-free ingredients can be more prone to sticking than regular versions.

Tip 3

Save some of the prettiest strawberry slices for garnish and arrange them just before serving to maintain their fresh appearance and prevent bleeding onto the white frosting.

Good to Know

Storage

Cover and refrigerate up to 3 days. Bring to room temperature 30 minutes before serving for best texture.

Make Ahead

Cake layers can be baked 1 day ahead, wrapped tightly and stored at room temperature. Frosting can be made 2 hours ahead and refrigerated.

Serve With

Serve at room temperature with a sharp knife dipped in warm water between slices for clean cuts through the frosting.

Common Mistakes

Watch

Don't overmix once flour mixture is added to prevent tough, dense cake texture.

Watch

Let layers cool completely before frosting to prevent melting and sliding.

FAQ

Can I use fresh strawberry puree instead of jam?

Yes, but reduce water to 2-3 tablespoons and add 2-3 tablespoons sugar to balance sweetness and maintain proper batter consistency.

What if my frosting is too thick or thin?

If too thick, add cream cheese 1 tablespoon at a time. If too thin, add more confectioner's sugar gradually until desired consistency is reached.

How long will this cake keep at room temperature?

Due to cream cheese frosting, this cake should not sit at room temperature longer than 2 hours. Store covered in refrigerator for food safety.
