This fluffy, moist and incredibly tasty low carb and keto blueberry cake, made with almond flour, is appropriate to have for breakfast!

This cake is truly excellent. Even high-carb eaters like it. The teenage Picky Eater ate her slice, then announced that "This cake is really good, Mom!" I nearly fainted.

I made this keto blueberry cake this afternoon. We each had a slice, and I carefully packed the leftovers in a sealed container and placed it in the fridge. Tomorrow I'm going to have a big slice with my morning coffee. ☕

A cake that you can eat for breakfast (occasionally)

I don't frost most of my cakes (except for keto carrot cake and keto birthday cake) deliberately so that I can have them for breakfast (this keto pound cake is a good example). I feel lucky that I can occasionally have cake for breakfast without feeling too guilty about it.

Certainly not every day. But once in a while, it's nice to have the option to have something sweet with your morning coffee.

The ingredients you'll need

You'll only need a few simple ingredients to make keto blueberry cake. The exact measurements are included in the recipe card below. Here's an overview of what you'll need:

Eggs: I use large eggs in most of my recipes, including this one.

Whole milk: You can use heavy cream instead if you prefer.

Unsalted butter: I'm partial to creamy European butter.

Vanilla extract: Try to use the real thing - pure vanilla extract - and not the artificially flavored stuff.

Sweetener: I use stevia. You can probably replace it with a granulated sweetener.

Kosher salt: If using fine salt, use less of it.

Almond flour: An excellent flour substitute that bakes exceptionally well. I use blanched finely ground flour. I don't recommend using a coarse almond meal in this recipe. There's a big difference.

Baking soda: If you'd like to try using gluten-free baking powder (though I haven't tested it in this recipe), remember that ¼ teaspoon of baking soda is equivalent to 1 teaspoon of baking powder.

Fresh blueberries: I don't recommend using frozen blueberries in baked recipes. I always use fresh. Please refer to the detailed discussion below.

Why I use stevia in this recipe

I like stevia and use it almost exclusively. I find that the glycerite formulation greatly reduces any bitter aftertaste.

However, do feel free to use your favorite granulated sweetener. The amount I use in this recipe is equal to about ½ cup granulated sweetener.

Use fewer blueberries when baking with almond flour

Since this keto blueberry cake is made with almond flour, which is not as absorbent as wheat flour, I limit the amount of blueberries I use to one cup. I fold half of them into the batter and scatter the remaining on top of the cake.

This achieves two goals. First, the cake looks so pretty with the blueberries on top! And second, the cake is not too moist with the juice of bursting blueberries that the almond flour is unable to absorb.

Can I use frozen blueberries?

The blueberries are wonderful in this cake. They add flavor as well as texture. I use fresh blueberries and haven’t experimented with using frozen blueberries.

But frozen blueberries are often mushy, and they tend to bleed into the batter and stain it. So, unfortunately, I can’t recommend using them in this cake, or in any of my baking recipes.

I think that frozen blueberries are great for making shakes and smoothies. They’re not really suitable for baking, in my opinion.

How to store leftovers

Once the cake is completely cool, I slice it, then place the slices in a paper towel-lined sealed container. The paper towels help absorb extra moisture. You can also successfully freeze slices of this cake, in freezer bags.
