Preheat oven to 375 degrees and line muffin tin with foil liners (they prevent greasy bottoms) or spray muffin tins with cooking spray. Mix dry ingredients and set aside. With a mixer beat eggs, milk and butter. Add dry ingredients and mix until just combined. Do not overmix or you will have big cracks in your muffins. Stir in blueberries gently. Bake for 20-25 minutes or until tops just start to brown.
