The Best Lemon Blueberry Cake, Low Carb – Trim Healthy Mama s

This Low carb, THM S Lemon Blueberry Cake is amazing!!

We went blueberry picking this week, yes in the heat. I have been working on a few blueberry recipes and this one is ready to share! It received two thumbs up from hubby. That is a big deal around here because he’s picky, especially when it comes to on plan desserts.

If you like lemon and blueberries, this is the sugar free dessert for you!!

This cake is perfect for spring and summer. The taste is light and fresh. It is perfect as a snack or the finish to a yummy dinner. You should be able to get 14 or so pieces of cake out of this recipe. This cake is great to store pieces in the freezer and pull out later for a treat. So, if you have a few pieces left, freeze them for later.

Here are a few tips

First, don’t drop the lemon in the cake batter when zesting it. The cream cheese can be the reduced fat version. It does need to be at room temperature. The butter and the eggs as well need to be at room temperature. I used allulose as the sweetener in the cake. My local Walmart had it on clearance and it worked great. The xanthan gum is optional. And, lastly, for the best texture pass your almond flour and coconut flour through a fine mesh sieve.

  • Excited to make this recipe – before I jump in, I have large eggs on hand. Would it be 6-7 large eggs to equal the 8 medium?

    My daughter made this for me and it was delicious! Even the “sugar-eating” guests thought it was fabulous and got two helpings. I put it in the refrigerator overnight and love that it tastes like a pound cake when it’s cold. Hands down my favorite THM/sugar free dessert. This cake does not taste “healthy” at all!! A real crowd pleaser.

      In the cake I used allulose. It measures 1 for 1 to sugar. I used confectioners swerve in the frosting.

  • Looks great! Have you tried in another pan, other than bundt? If so, how would cook time vary? thanks for sharing!

      What pan are you wanting to use? A 9×13 pan might be 40ish minutes.
