Preheat the oven to 350℉. Line a 12-muffin tin with muffin liners.
In a large bowl, stir together the almond flour, monk fruit/allulose sugar substitute, baking powder, and sea salt.
Melt the butter in the microwave in a small bowl. Stir in the almond milk, eggs, and vanilla extract.
Mix the wet ingredients into the dry ingredients. Stir well and let the batter sit for at least 2 minutes. Then stir in the 3/4 pint of blueberries and the lemon zest.
Pour the batter into the 12 muffin cups. Then top the muffins with the remaining blueberries. Bake for 20-25 minutes, or until the tops are a nice gold color and toothpick inserted into the center comes out clean.
