2 T Melted Butter
1 T Olive Oil
1 C Skim Milk
1 Egg
1 1/2 C Whole Wheat Flour
1/2 C Sugar (or 1/3 C Honey)
2 t Baking Powder
1/2 t Cinnamon
1/t Salt
2 C Blueberries
Melt the butter. Stir in olive oil and milk to cool down the liquid. Stir in egg. Add flour, sugar (or honey), baking powder, cinnamon, and salt. Mix until just combined. Fold in blueberries.
Preheat oven to 350F. Spray muffin pan with cooking spray or line with cupcake liners. Divide batter amongst 6 jumbo muffin tins, or divide between normal size muffin tins.
Bake about 30-35 minutes or until toothpick comes out clean. If you used honey you may want to lower temp to 325 since they will brown faster.
