New York Crumb Cake (tastes Like Starbucks Pastry)

Why I Love This Recipe
Ingredients You'll Need
2 Tbls. oil
4 cups flour
1/2 C sugar
21/2 tsp. baking powder
1/2 tsp. salt
1 large egg
1/2 C milk
2 tsp. vanilla
1 c. packed light-brown sugar
2 tsp. cinnamon
1 C unsalted butter, melted and cooled (I used one of each as I didn't have enough unsalted)
Confectioners sugar for dusting
Directions
Heat oven to 350 with rack in middle.
Lightly brush 9 by 13 baking pan with oil, dust with flour, tap to remove excess.
In medium bowl sift together 11/2 C flour, granulated sugar, baking powder, and salt. In second bowl, whisk egg, milk, oil, and vanilla. Fold dry ingredients into egg mixture.
Spread batter into pan and set aside. (use hands to pat down if spoon does not do the trick) Combine remaining 2-1/2 C flour, brown sugar, and cinnamon.
Pour butter over and toss with spatula until large crumbs form.
Sprinkle over batter.
Bake rotating pan after 10 minutes.
Continue baking until tester comes out clean. Maybe 10 more minutes.
Cool.
Dust with powdered sugar and cut. Yum!
NOTES: I baked it in an 11 x 7 pan; added nuts between the batter and the topping.
It's a wonderfully rich recipe!
Next time I might try putting some raspberry jam between the layers.
