So, I tried this recipe this morning and it was really good! I substituted buttermilk for the milk, however, as I had some extra and buttermilk makes everything better;-) It was a bit dry so I added about 1/8 of a cup more of the buttermilk. Super good and the crumb topping is not flour-y at all the way some are.
1 1/2 cups all-purpose flour
3/4 cup white sugar
1/2 teaspoon salt
2 teaspoons baking powder
1/3 cup vegetable oil
1/3 cup milk
1 cup fresh blueberries
1/2 cup white sugar
1/3 cup all-purpose flour
1/4 cup butter, cubed
1 1/2 teaspoons ground cinnamon
Preheat oven to 400 degrees F (200 degrees C). Grease muffin cups or line with muffin liners.
Combine 1 1/2 cups flour, 3/4 cup sugar, salt and baking powder. Place vegetable oil into a 1 cup measuring cup; add the egg and enough milk to fill the cup. Mix this with flour mixture. Fold in blueberries. Fill muffin cups right to the top, and sprinkle with crumb topping mixture.
To Make Crumb Topping: Mix together 1/2 cup sugar, 1/3 cup flour, 1/4 cup butter, and 1 1/2 teaspoons cinnamon. Mix with fork, and sprinkle over muffins before baking.
Bake for 20 to 25 minutes in the preheated oven, or until done.
