This Keto Berry Cake has a layer of berries hidden by a fluffy cream cheese frosting. The juice from the berries soaks into the cake under them keeping it moist and flavorful. My mixed berry cake is simple but delicious and easy enough to make often. This easy recipe is low carb, keto, gluten free, grain free, sugar free, and Trim Healthy Mama friendly.
My husband and I celebrated our 16th wedding anniversary this past summer. A few months before our 13th anniversary I decided I wanted to remake our wedding cake. And then a few weeks after our anniversary, I realized I had forgotten all about my special dessert idea. So I made this keto berry cake last week. As they say, better late than never, and this was less than a month late. Not too bad.
My wedding cake was a white cake with a berry filling and cream cheese icing. It was my compromise because as a young couple with a limited budget we couldn't afford the fondant covered cake I really wanted. I toyed with the idea of making our wedding cake but was talked out of that idea pretty quickly. I did make berry sorbet spiked with riesling that we served along with this cake. The berry cake plus a refreshing sorbet was perfect.
How to Make Keto Berry Cake
The cake portion of this is super easy. I generally don't bother adding ingredients in stages for a recipe like this that is just baked in an 8x8 glass baking dish.
I just add all the ingredients to a mixing bowl and mix until smooth. This takes about 5 minutes total which includes measuring out the ingredients.
How to Make Cream Cheese Frosting
I love cream cheese icing. I could really just eat it by the spoonful. It is also easy to make. You just need to beat the cream cheese with powdered sweetener. Sometimes I add butter and vanilla but all that is really needed is the cream cheese and sweetener.
Tips & Substitutions
Cream Cheese Icing: If it is too thick you can thin it with some cream or almond milk. In this recipe, I do thin it with cream.
Flour Options: Almond flour can be pricey. If you'd like to cut back on the amount used in this mixed berry cake you can use ½ cup almond flour and ½ cup ground golden flax.
Nut-Free Option: The best sub for almond flour is sunflower seed flour. It can be subbed 1:1 for almond flour; unlike coconut flour.
White Cake: For a lighter cake my Keto Vanilla Cake is perfect in this recipe!
Do I need to use frozen berries for Keto Berry Cake?
Yes, for this recipe frozen berries work best. They release their natural juices to soak down into the cake and make it moist and flavorful.
