1 2/3 cups quick cooking oats
2/3 cups flour
1/2 cup whole wheat flour
3/4 cup light brown sugar
2 tsp cinnamon
1 tsp baking powder
1 tsp baking soda
3/4 tsp salt
1 1/2 cup buttermilk (or milk and lemon juice)
1/4 cup oil
1/4 tsp cloves
2 cups frozen apples (they used blueberries)
2 tbsp flour
Preheat oven to 400. Place oats in food processor, pulse 5-6 times or until oats resemble coarse meal. Place in a large bowl. Add flours and next 5 ingredients (through salt) to oats; stir well. Make a well in the center of mixture.
Combine buttermilk and next 3 ingredients (through eggs). Add to flour mixture; stir just until moist.
Toss apples with 2 tbsp flour, and gently fold into batter. Spoon batter into muffin cups coated with cooking spray. Bake at 400 for 20 minutes. Cool on wire rack.
Makes a dozen muffins (they got 16 but I think they used cupcake tins while I used muffins tins).
