Low Carb Strawberry Frosting

I know strawberry cake is favorite in the south and sells out anytime it’s on a restaurant menu, because it hits all those food memory points. Someone’s grandma made the best strawberry cake or every time we had a get together we had to have the strawberry cake.

Low Carb Strawberry frosting is not easy to make. Strawberries are 92% water and this has to be cooked out or roasted out prior to making a frosting that can you can pipe. What you want is intense flavor without the water that compromises the frosting.

Roast the Strawberries for Low Carb Strawberry Frosting 

I like to roast the strawberries to intensify the flavor and then blend them. You can also choose to cook the strawberries on top of the stove on very low and reduce down as much as possible to eliminate the water and intensify the flavor.

You do not have to pipe the frosting if you want to use a little less. I love a smooth topping with a fresh strawberry or sprinkles. You can get sugar free sprinkles from Stoka.

  1. Love this idea for keto treats! Do you think the butter and cream could be subbed with margarine or coconut oil and thickened coconut cream in place of the cream? Im doing keto and cannot do dairy so always looking for those dairy free options too. Thanks!

  2. This looks so good! I can’t wait to try this. I was wondering, how long do I reast the strawberries? I couldn’t find the time in the notes or recipe.

  3. You could probably use dehydrated strawberries and grind them for this icing. Trader Joe’s are good with tons of strawberry flavor. Just a thought. Have you ever used allulose in your frostings?

    1. Dehydrated stawberries have a lot of sugar in them. 20 grams sugar. I can’t use those. I do not use allulose. I use powdered erythritol from Swerve. But I’ve been thinking of trying allulose.
