Flavorful and delicious keto Low carb lemon blueberry cream cake is the perfect gluten-free, sugar-free dessert for any party. #ketodesserts #lowcarbdesserts

Going back through the memories of my absolute favorite cakes ever, I immediately think of a certain cake brought in to us teachers one year during teacher appreciation week.

I was teaching high school French, and nearing the end of the year. Some of the awesome parents at our school arranged a special luncheon every single day for the teachers that week, and one glorious lady brought in several cakes. She arrived with some sort of chocolate tiramisu, a cinnamon cream, and the most amazing lemon blueberry cream cake I’ve ever tasted.

I’ve tried for years to find the perfect recipe to replicate this deliciousness in a keto-friendly, sugar-free, low carb form, and my low carb lemon blueberry cream cake is pretty amazing!

In a hurry?

In the following article, you’ll find my helpful tips and stories. If you don’t have time, scroll down to the bottom for the printable recipe or PIN it here for later!

How to juice a lemon

I love lemons in the summer! Lemon curd, lemon pie, lemon bars, lemonade, you name it! Both the juice and zest have amazing flavor and can be used for different things.

There are several ways to juice a lemon depending on what appliances you have or don’t have. I use a basic jar with a juicer on top with holes in it to keep out the seeds. Or, my latest find is the fabulous Pampered Chef Citrus Press (I use it ALL the time). However, if you don’t have anything but a fork it’s still super-easy to juice.

First, take your lemon and roll it on the table, pushing it down to start the juices moving. Second, cut the lemon in half.

Then, take a fork and half a lemon holding it over a bowl to collect the juice. Put the fork in the middle of the lemon squeezing around as you go all along the rind to get as much juice out as you can.

As far as zesters go, I prefer a sort of a rasp to make smaller pieces of zest to flavor your bakes. Some people prefer larger, it’s really up to you! Here are a few examples:

🔪 Instructions

How to bake the low carb lemon blueberry cream cake

First of all, whenever you bake a cake, gather all your supplies and ingredients. To start, take two round 9-inch pans and trace around them with a pencil on parchment paper.

Cut out two circles of parchment paper to line the bottoms of the pans. Once the parchment paper’s in place grease the paper and sides of the pans with coconut oil and set those aside.

Combine the ingredients

Next, grab a large bowl and combine the butter, sweetener, and heavy cream with a mixer. For sweetener choose a powdered or confectioner’s style sweetener, I use Swerve confectioner’s, and it works very well in this recipe. Once that’s all combined with no lumps mix in the eggs one at a time on high speed. Then mix in the vanilla, lemon juice, lemon zest, and extra extract if you’re using it.

Now you’re going to add in the dry ingredients. Mix in the almond flour, coconut flour, baking soda, and salt. I’ve had some questions about different almond flours. For this recipe, try to use a finely ground, blanched almond flour for best results.

After that’s all combined with no lumps, gently stir in one cup of frozen or fresh blueberries. Make sure they’re evenly dispersed then divide the batter between the two cake pans.

Bake at 350 degrees for about thirty-five minutes and remove when your toothpick comes out clean. Ovens can vary in temperature, and I’m at a high altitude so may need to extend the time by ten minutes so just keep an eye on it.

Then remove the pans from the oven to rest about ten minutes. Last, remove the cakes from the pans and leave to cool completely.

How to make a low carb sugar-free frosting

Use your mixer again to combine the butter, cream cheese, and sweetener in a medium-sized bowl. Mix it at a high speed until there are no lumps. Add the heavy cream, vanilla, lemon zest, lemon juice, lemon extract, and salt. Now, mix it together until it’s a spreadable frosting consistency.

To frost the cake

Now it’s the fun part! To frost the cake place the first cake on a serving plate. Then spoon about a third of the icing on the cake and spread it around evenly. Gently, place the second cake on top. Next, put another third of the frosting on the top and spread it around. Use the rest of the frosting to cover the sides and even out the top.

Last but not least, decorate the top middle with a fourth to a half a cup of blueberries. Refrigerate it to set until ready to serve.

I made this for a family dinner that got cancelled. Since it's not frosted, can it be frozen? I can't eat the entire cake by myself!


Saturday 15th of January 2022

Yes, it can definitely be frozen. If it's not frosted, I would cover it in foil and put it in a freezer-safe air-tight container. Or, if you have a freezer bag large enough for it to fit into, make sure you get all the air out and freeze it in that. I wouldn't leave it longer than 1-2 months in the freezer. Thaw by moving to the refrigerator and remove the foil or bag, but still in an in an air-tight container, the day before you frost and serve. Sometimes I also cut up cakes in portions and freeze them so I can take one out at a time.

Thank you so much for sharing this recipe! I just made this today for my mother in laws birthday (she follows a sugar free and gluten free diet). I’m so excited for her to be able to enjoy a piece of cake again! The only thing I did differently was baking the cakes in 2, 6” pans so that it was smaller and taller. Thanks again! Wish I could post a photo!

I love hearing this! Thanks for commenting. I'm so happy she liked it! ;)
