1/2 c. milk
1/4 c. oil (I used peanut oil, but you could use any bland oil you have)
1 1/2 c. whole wheat flour
1/2 c. sugar
1 T. baking powder
1 c. frozen berries (I used Trader Joe's Very Berry Medley, which has strawberries, blueberries, blackberries and raspberries. Having that in the freezer was the motivation for the muffins in the first place. I didn't thaw the berries first, but did slice the strawberries into about 4 pieces each.)
Preheat oven to 400 degrees.
Beat egg. Stir in milk and oil.
Combine dry ingredients. Stir into liquid mixture until flour is just moistened.
Fold in berries. Mixture will be lumpy.
You're probably supposed to grease the muffin tin, but I have a nonstick one so didn't bother. Fill the muffin cups about 2/3 full.
Bake 20-25 minutes.
