New York Crumb Cake
Directions:
Place rack in center of oven, and heat to 325°F. Lightly brush a 9-by-12 1/2-inch baking pan with canola oil, dust with flour, and tap to remove excess. Set aside.
In a medium bowl, sift together 1 1/2 c flour, granulated sugar, baking powder, and salt; set aside.
In a second bowl, whisk together egg, milk, canola oil, and vanilla. Using a rubber spatula, fold dry ingredients into egg.
Spread batter evenly into prepared pan, and set aside.
In a medium bowl, combine remaining 2 1/2 c flour, brown sugar, and cinnamon. Pour melted butter over flour mixture, and toss with a rubber spatula until large crumbs form.
Sprinkle crumbs over batter, and bake, rotating pan after 10 mins.
Continue baking until a cake tester comes out clean, about 10 mins more.
Transfer baking pan to a wire rack to cool. Dust with confectioners sugar.
Using a serrated knife or bench scraper, cut into 3-inch squares.
Store in an airtight container for up to 3 days.
