DIRECTIONS:
Step 1
Preheat the oven to 350°F. Grease 12 wells of a standard muffin pan, or line with papers.
Step 2
Stir together the dry ingredients in a medium-sized bowl; set aside.
Step 3
Whisk together the melted butter, Swerve, eggs, almond milk, yogurt, lemon zest or extract, and vanilla.
Step 4
Stir the dry mixture into the wet ingredients. Scrape the bottom and sides of the bowl, and continue to mix just until blended - a few lumps will remain.
Step 5
Fold in the berries.
Step 6
Fill the muffin cups almost full. Sprinkle with cinnamon-sugar, if desired.
Step 7
Bake for 23 to 26 minutes, until a cake tester inserted into the center of a muffin comes out clean.
Step 8
Remove the muffins from the oven, and after 5 minutes transfer them to a rack to cool.
Makes about 12 servings.
