Heat oven to 400 degrees F. Grease a standard muffin tin with butter and flour. Set aside.
In a large bowl, combine the dry ingredients: all-purpose flour, baking powder, and salt. Set aside.
In a small bowl, combine frozen blueberries and 1 tbsp of all-purpose flour. Set aside.
In a large mixing bowl, combine the granulated sugar and melted butter. Use either a stand mixer or hand mixer on medium/low, beat until combined. Add one egg at a time, allowing each to combine with the butter and sugar. Continue to add the buttermilk, maple yogurt and vanilla on medium/low until everything is combined.
Slowly add the dry ingredients with the stand mixer/hand mixer on low until just moistened.
Using a spatula, gently fold the flour coated blueberries into the batter.
Scoop batter into greased muffin tins using an ice cream scooper, about ¾ full.
Bake at 400 degrees F for 15-18 minutes.
Remove from oven and allow to cool for about 15 minutes, remove each muffin from muffin tin and allow to cool the rest of the way on a cooling rack.
