Blueberry Muffins

1 1/2 cups flour (I use wheat and it tastes great)
3/4 cup white sugar
1/2 tsp salt
2 tsp baking powder
1/3 cup oil (saflower is best and better for you)
1 egg
1/3 cup milk
1 cup blueberries

Optional Topping
1/4 cup butter
1/2 cup white sugar
1/3 cup flour
1 1/2 tsp cinnamon

Preheat oven to 400 degrees. Grease muffin pan. Mix all ingredient in bowl except blueberries until just blended. (If you stir muffin mixes very much you end up with a rubbery muffin). Then add the blueberries and fold into the rest of the dough so as not to crush them. (I use frozen blueberries) Place in muffin pans. If you desire to use the topping melt the butter then add the rest of the ingredients and place on top of the muffins. Bake for 15-20 minutes on the bottom rack or the bottom of them will burn before they bake through. Enjoy!
