Apple-Scotch Snack Cake

Preheat oven to 350° F. Grease bottom of 13 x 9-inch baking pan.

Combine 2/3 cup oats, 6 tablespoons flour, 4 tablespoons butter and 3 tablespoons brown sugar in small bowl. With clean fingers, mix until crumbly; set aside.

Combine 2 1/4 cups flour, 1 cup oats, baking powder and salt in large bowl. Combine 1 cup brown sugar and eggs with wire whisk. Whisk in 1 1/4 cups milk, melted butter and vanilla extract. Add to flour mixture all at once; add apples. Stir gently until just combined. Pour into pan. Sprinkle with 1 cup morsels; crumble topping evenly over morsels.

Bake for 40 minutes or until golden brown and wooden pick inserted in center comes out with a few moist crumbs clinging to it. Remove from oven to wire rack.

Microwave remaining 1/3 cup morsels and 1 1/2 teaspoons milk in small, uncovered, microwave-safe bowl on MEDIUM-HIGH (70%) power. The morsels may retain some of their original shape. If necessary, microwave at additional 10- to 15-second intervals, stirring just until smooth. Carefully drizzle over hot cake in pan. Cool in pan at least 30 minutes. Cut into squares; serve warm or at room temperature with ice cream, if desired. Store tightly covered at room temperature.
