Combine first 6 ingredients (through the vanilla extract) in your blender and blend for about 30 seconds. Add the rest of the ingredients, except for the blueberries, and blend for about 1 minute. You could also use a hand mixer or food processor if you don't have a blender.
Fold in blueberries and divide batter between 12 prepared muffin cups. Bake for 25 to 30 minutes or until a toothpick inserted into the middle comes out clean.
Transfer muffins to a wire rack to cool then enjoy!
Notes
*I prefer my muffins slightly sweet and love this combo of honey, lemon and vanilla with blueberries, but feel free to add more honey if you like your muffins sweeter!
