Preheat the oven to 375 degrees.

Combine all the dry ingredients together. Set aside.

Cream the butter and sugar together, until just creamed. If you leave the stand mixer running as they are creaming, these muffins will not rise. Simply cream them until combined.

Add the eggs, one at a time, mixing after each egg.

Add one half of the dry ingredients, mixing well.

Add one-third of the yogurt and combine until well mixed.

Add one-half of the remaining dry ingredients to the mixture, and combine. Continue this, alternating the yogurt and dry ingredients, until you have mixed both of them in, completely.

Add as many blueberries as you can.

Oil a muffin tin well, then sprinkle a little cornstarch or white rice flour on the bottom of each cup.

Fill each space for muffin two-thirds full. Sprinkle the raw sugar over the top and set them in the oven.

Bake the muffins for about 35 minutes, or until the tops have browned and started to harden, and the entire house smells of warm blueberry muffins.

If your sweetie wakes up from the smell, the muffins are done.
