How Much Sugar is in Blueberries?

Fruit has it’s own natural sweetener, so these muffins won’t be completely sugar free because you have to account for the macros in the fruit. This recipe requires 3/4 cup of blueberries, which has 11 grams of sugar, which is divided among a dozen muffins.

What Type of Sweetener to Use

I like to use Lakanto’s granular monkfruit sweetener Monkfruit is zero-calorie, zero-carb, and is made without the use of artificial sweeteners. The best thing about it, is it measures 1:1 to like table sugar. This makes it super easy to convert conventional recipes. No need to look into a conversion table, it’s an even swap, which is super convenient!

It also tastes like sugar. There’s no aftertaste or cooling effect like you find with some sweeteners. The perfect mix of monk fruit extract and erythritol with no fiber, no maltodextrin, and no artificial flavoring or sweeteners.

If you want to use something like pure maple syrup (which does have sugar) you can start with 1/3 cup, adjust to suit your tastes.

Can You Substitute All-Purpose Flour for Almond Flour?

You can use almond flour as a substitute for many recipes using all-purpose flour, but it isn’t a 1:1 switch. Almond flour and all-purpose have 1:2 ratio, 3/4 cup all-purpose flour = 1 1/2 cups almond flour.

How to Keep the Muffins Healthy

The right sweetener is key here. I recommend zero carb and zero calorie organic monkfruit. You can grab it here and use the Discount Code STAYSNATCHED. The key to healthy muffins is also blanched almond flour as opposed to all-purpose flour.

How to Keep the Muffins Moist

As noted above, do not use coconut flour. Coconut flour will dry out the muffins. Use fresh blueberries. Blueberries will produce a moist texture since they are filled with water. Using melted butter is also key in this recipe.

How to Store the Muffins

Store the muffins tightly sealed in the fridge. They will last for 5 days.

How to Keep the Muffins From Falling Apart

  • Do not overmix the batter. Use a silicone spoon and only beat to combine the ingredients.
  • Fill each muffin tin about halfway.
  • Remove the muffin cups from the tin immediately upon removing the tin from the oven.
  • The longer the muffins stand, the less soft they will become. They will firm more as they stand.

What if I don’t have almond milk? I’m not a fan of it. What if I used whole milk? What difference would it make in the baking?
