 I love these low carb lemon blueberry muffins with a sugar free lemon glaze and I think you will too, as they are one of my top sellers in my keto bakery.

 The texture is fluffy and lemon glaze is sweet and tart. If you can find those big giant blueberries, you will have a little extra sweetness. 

Using Lemon Extract for Low Carb Lemon Muffins

Lemon muffins made with almond flour are a little tricky. If you use too much lemon juice, you don’t get the right muffin texture.  However, you really have to drive the lemon flavor up to know it’s there.  I was able to use less lemon juice than I do for my lemon cake and added in lemon extract. The result is much fluffier muffin. Do not overdo the extract. 

Taste taste: I alway take a teaspoon of batter and microwave it to make sure it tastes good. Do this before you are tempted to add more lemon extra. 

In addition to the lemon extract, I used the juice and zest of one lemon and an addition of sour cream. I am thrilled with the results, as are my customers.

Lemon glaze is so simple. I start with one cup of Swerve confectioner’s sugar, add squeeze of half a lemon and add more water if needed. I also add a little zest.

I use Swerve.

Swerve is my sugar free sweetener of choice. Swerve is a powdered erythritol that comes in both granulated and confectioner’s. I wrote an article here about Swerve and why I use it. 

How many blueberries do you put in each low lemon blueberry muffin?

I like to use those giant blueberries if I can find them, as they are sweeter, and put about 4 extra large or six regular. You can put as many as you like, but keep in mind, blueberries add a lot of moisture to your bakes.

Is this cake keto friendly and gluten free?

Yes there are about 2 net carbs per muffin and there is no gluten.

Why are my keto cake recipes better than most?

My keto cake recipes are better than most, as I’ve made about 6,000 muffins in my bakery. I make sure the sponge cakes taste and texture is like regular cake. Many keto muffins and biscuits are too eggy or fall apart. It’s critical to get just that right mix of flours and sweetener. 

Where do you get those tart cups?

I love these tart cups that make eating and sharing easier. I buy them on Amazon. However, regular muffin liners work well too, although you may need to bake 5 to 10 minutes longer.
