Grandma Behrmann's Coffee Cake

Everyone loves this breakfast delight. The best part about it is that it's so easy to make and sooo delicious! Enjoy

1 1/2 c sugar
3 Tbsp. melted butter (melt 1 cube and save the rest for later in the recipe)
3 beaten eggs
Mix these together and add:
3 tsp. baking powder
3 c flour
1 1/2 c milk
1 tsp. vanilla
Mix until smooth and pour into greased 9X13 inch cake pan. Over the top pour:

3/4 c brown sugar mixed with 2 Tbsp. cinnamon, then pour melted butter over top. Bake at 350 for about 30 minutes or until center is done. Dave like to put butter on it after it's cooked.
