Blueberry muffin preparation
Whisk melted butter, vegetable oil, eggs, and milk (or buttermilk) in a bowl. Whisk until the mixture is uniform.
In another bowl add 2 1/2 cups of flour that you have sifted, baking powder, baking soda, and stir to combine.
Combine the whisked egg mixture and the dry ingredients in a bowl, stir to combine.
Sprinkle 1 tablespoon of flour over the blueberries, then add the blueberries to the muffin batter, stir only until they are mixed. If you overmix the batter after you add the blueberries the blueberries will burst and turn the batter purple.
Grease muffin tin with non-stick spray.
Fill the muffin tins 2/3 full of batter. Top with streusel mixture.
Bake at 425 degrees for 10 minutes. Lower the oven temperature to 375 and bake for another 10 or 15 minutes.
