I received this recipe from an email this morning from the www.kingarthurflour.com website. Sounds interesting! "This dense, moist cake is a perfect base for its white sugar crumb topping. Watch out when you cut it; in typical crumb cake fashion, the topping will scatter a bit." Tips from our bakers: For a blueberry crumb cake, sprinkle 1 cup fresh or frozen blueberries atop the batter in the pan before baking.
For more distinct crumbs on top, prepare the topping with 1/4 cup vegetable shortening and 4 tablespoons butter, cut in chunks, in place of the 4 tablespoons melted butter. NOTE: The recipe online also calls for an ingredient called BUTTERY SWEET DOUGH FLAVOR as optional. 1/2 teaspoon in the cake part and 1/4 teaspoon in the topping part. Zaar did not recognize this ingredient so I couldn't add it in. It's something that you can order online from the www.kingarthurflour.com website. :-)
