I’m sharing this easy recipe for keto blueberry crumb muffins, as it’s one of my most popular sellers in my keto home bakery. It’s the one people order over and over again. Once you taste the sweet muffin filled with blueberries with a crunchy cinnamon crumb topping, you’ll be addicted.

These are very similar to my coffee cake muffins with the added pleasure of blueberries, a super fruit that loves cinnamon. Keto blueberry crumb muffins are Low Carb, Keto Friendly, Gluten Free. These are great for breakfast and will keep you filled up easily all the way to a late lunch.

Fresh or Frozen Blueberries

We used hand-picked fresh blueberries in the recipe; You can also use frozen blueberries in this recipe. I just take them out frozen, while assembling my ingredients. They are ready to be placed in each muffin by that time.

You may be curious about berries and their carb count. I used about 60 grams of blueberries for 12 large muffins, 14 small muffins, accounting for about less than 12 grams of carbs for entire recipe.

Can you Make this into a Keto Blueberry Crumb Cake?

Yes, you can put this batter into a ten inch or nine inch cake pan. Only fill your pan 3/4 of the way full. You may still get a few muffins out of it. You may need to cover with aluminum foil for the last ten minutes.

How Can You Tell if Your Muffin or Cake is Done?

I always use a food thermometer. Cake is done at 210 degrees F. I will take a cake out when the middle of the cake reaches 207 degrees F. Sticking a toothpick in a cake is not a reliable way to measure cake.

What kind of Muffin Liners do I Use?

I use tart liners because they work best in my bakery and get about 14. These are great because, you don’t use a muffin tin. You use a baking sheet. They are easy to bake, eat, and share. You can use whatever you like. These take about 16 minutes to bake as they are flat. If you use typical muffin liners, you may get as many as 16 and it may take up to 25 minutes to bake, depending on size.
