Orange Streusel Coffee Cake

We had this for breakfast this morning. Don't worry, there's no coffee in it.

Orange Streusel Coffee
From SOAR--the searchable online archive of recipes of Berkeley

       Yield: 12 Servings
  
       2 c  Flour
     1/2 c  Sugar
   2 1/2 ts Baking powder
     1/2 ts Salt
            Grated rind of 1 orange (I
            Used 2 oranges)
       1    Egg, beaten slightly
     1/2 c  Milk
     1/2 c  Orange juice
     1/3 c  Oil (I used extra-virgin but
            Canola would be fine)
 -STREUSEL TOPPING-
     1/4 c  Flour
     1/4 c  Sugar
       2 tb Grated orange rind
       2 tb Butter (I grated it)
  
   Sift the first 4 ingredients into a large bowl and then add the grated
   orange zest.  Make a well in the centre and pour in the egg, milk,
   orange juice and oil.  Stir just enough to moisten.  Pour into a 9″
   square pan (I used a 9″ round pan, which worked perfectly).  Sprinkle
   the well mixed streusel ingredients, evenly over the top.  Bake in a
   350F oven for about 30 mins.  This coffee cake was wonderful and only
   lasted for 1 day in our house!

We really liked this coffee cake. 
It had also been a very long time since we had any white flour at all, so that probably helped its case.  The other two wished it was a little sweeter, but I thought it was plenty sweet.  It wasn't the awesomest coffee cake ever, but it was pretty darn good, so I'll remember this recipe for future use.
