Ingredients
1 3 ⁄ 4 cups German chocolate cake mix with pudding in the mix
1 ⁄ 2 cup water
1 ⁄ 4 cup vegetable oil
2 eggs
1 ⁄ 2 cup packed brown sugar
1 ⁄ 3 cup all-purpose flour
1 ⁄ 3 cup quick-cooking or old-fashioned oats
3 tablespoons butter or margarine, softened
3 ⁄ 4 teaspoon ground cinnamon
1 ⁄ 4 teaspoon ground nutmeg
Instructions
1Preheat the oven to 350°F, or 325°F if using a dark or nonstick pan. Coat the bottom of an 8-inch or 9-inch square baking dish with a flour-based baking spray.
2Combine the cake mix, water, vegetable oil, and eggs in a large mixing bowl. Blend with an electric mixer on low speed for 30 seconds, then increase to medium speed for 2 minutes, scraping down the sides as needed. This ensures a smooth, aerated batter for a lighter crumb. Pour the batter into the prepared pan.
3Stir the brown sugar, flour, oats, softened butter, cinnamon, and nutmeg together in a separate medium bowl until thoroughly combined. Scatter this oat mixture evenly over the cake batter.
4Bake for 32 to 36 minutes, or until a toothpick inserted into the center comes out clean. Let the cake cool in the pan for at least 30 minutes before slicing into squares.
Notes
Transport: If you plan to tote this cake to a picnic, bake it in a disposable foil pan so you don't have to carry home a dirty dish.
Storage: Keep leftover cake tightly covered at room temperature for up to 3 days.
Make ahead: You can bake this the night before. The streusel topping stays crisp while the cake remains moist.
