Keto Lemon Blueberry Muffins

What do you do when you have an extra container blueberries? Make Keto Lemon Blueberry Muffins of course.

These babies are a great way to use up leftover blueberries or raspberries whether they be frozen or fresh!

Keto Lemon Blueberry Muffins are gluten free, sugar free and low carb! These muffins are VERY filling and make a perfect make-ahead breakfast or snack.

They are super soft in the centre with a crunchy delicious crumble topping and sweet glaze.

These are the kind of muffins your dream about on a Sunday morning.

Low Carb Lemon Blueberry Muffin Ingredients:

• Almond & Coconut Flour – I use the Kirkland Costco brand of almond flour (I buy it in bulk on Amazon or at Costco itself occasionally) and this brand of coconut flour for this recipe. As I’ve noted in many of my past recipes, the brand of almond and coconut flour can affect the final outcome of the recipe because absorbency can vary depending on how the flour has been processed.

What if I don't have Xanthan Gum?

• If you don't have Xanthan Gum don't worry! You can still make these. It just provides a nicer “doughy” texture to the muffins. I would suggest picking some up in the future because it's great in almost all keto desserts and one bottle lasts a long time!
• As a substitute you can try adding 1 tsp of cornstarch or 1 tsp of flax OR just leave it out altogether.

Can I substitute Coconut Flour for Almond Flour when making Keto Lemon Blueberry Muffins?

• Typically NO. This substitution would not be a 1:1 change. Coconut Flour is much MORE absorbent than Almond Flour.
• If you still want to attempt it (as it can be possible though the muffins may be a slightly different texture) then try subbing an extra 1/2 cup coconut flour and 1 extra egg for the 1 cup of almond flour in the muffins. If your batter is super thick, add an extra tablespoon of cream as well.
• In terms of the streusel topping, it would be the same idea, you'd probably want to try 1/2 cup coconut flour in place of the almond flour/coconut flour combination and go from there (add more if the dough is not starting to crumble but be sure the dough isn't TOO dry or the topping will brown too fast).

Can I substitute Almond Flour for Coconut Flour When Making Keto Lemon Blueberry Muffins?

• Typically NO. This substitution would not be a 1:1 change. Almond Flour is much LESS absorbent than Coconut Flour.
• If you still want to attempt it (as it can be possible though the muffins may be a slightly different texture) then try subbing an extra 1 cup almond flour for the 1/2 cup coconut flour in the muffins, see how your batter looks, it should be quite thick. If not, add another 1/4 cup almond flour. (This should mean your muffins will contain 2 1/4 cup almond flour total).
• In terms of the streusel topping, it would be the same idea, you'd probably want to try 1 cup + 2 tbsp almond flour instead of coconut flour and go from there.

Can I use a different sweetener to make Keto Lemon Blueberry Muffins?

• Yes, you can use another sweetener, just be sure to account for the fact that some sweeteners measure different than others. The powdered monkfruit/erythritol blend that I use is just slightly sweetener than sugar but a sweetener like Truvia will be 3x as sweet so just make sure to use more or less depending on the sweetener.
• Also, if using a granular sweetener you may find your streusel topping to come out slightly different than mine as a powdered sweetener tends to thicken the dough more. Don't worry too much about this, you just may need to add an extra tablespoon of coconut flour to your topping.

Tips For Making Keto Lemon Blueberry Muffins

• When making the streusel topping, add the extra tablespoon of coconut flour if needed. You want the mixture a bit crumbly but not TOO dry.
• When baking these muffins, watch the time. My oven bakes more slowly than others typically but mine took about 30min total. Don't take them out under-done! Make sure a toothpick comes out clean first.
• If you find the streusel topping to be browning too quickly when baking them, try baking them on a lower rack in your oven.

Lowering the Calories and Carbs in Keto Lemon Blueberry Muffins

• If you'd like lower calorie keto blueberry muffins, feel free to leave off the streusel topping and just add the glaze! This will save you about 95 calories per muffin making them 205cals instead.
• The new macros would be 17.5g of fat, 4.9g NET carbs, 4.9g protein and 3.5g of fibre
