1 cup yogurt
1/4 cup melted butter
1 tsp vanilla
1 cup chopped strawberries, fresh or frozen

Mix together flour, sugar and baking soda. In another bowl, mix eggs, yogurt, butter, and vanilla. Toss strawberries in flour mixture. Pour yogurt mixture into flour and stir gently. Spoon into greased muffin pans. Bake 18 minutes at 375 degrees.

I've been working on developing various kinds of muffins from a master muffin mix recipe. We've been eating muffins quite frequently the past weeks as I've tried different recipes. This was a favorite and perfect since we have fresh berries. I have successfully made it using frozen berries as well.

I hope to be sharing the results of my muffin mix experiments soon. Meanwhile, do you have a favorite muffin recipe that I could try? I'd especially like to find a good streusal topping.
