Desserts Cakes Cake Mix Cake Recipes Yellow Cake Outrageously Buttery Crumb Cake 4.6 (106) 93 Reviews 34 Photos This simple crumb cake is the best I ever tasted. The cake is so moist, and there is a ton of buttery crumb topping to die for. It's my aunt's recipe from the 1970's (hence the 1 pound of butter) and therefore of uttermost decadence, but oh so delicious! I've made this recipe so many times, with so many compliments.

Something went wrong. Our team is working on it. Original recipe (1X) yields 16 servings 1 (15.25 ounce) package yellow cake mix ⅔ cup water 3 large eggs ½ cup butter, softened 1 ⅓ cups packed brown sugar 1 tablespoon ground cinnamon, or to taste 1 tablespoon vanilla extract 4 ½ cups all-purpose flour 1 ½ cups cold butter, cubed 1 tablespoon confectioners' sugar for dusting (Optional) Directions Gather all ingredients. Dotdash Meredith Food Studios Preheat the oven to 350 degrees F (175 degrees C). Grease a 12x18-inch jellyroll pan. Beat yellow cake mix, water, eggs, and 1/2 cup softened butter together with an electric mixer in a mixing bowl until thoroughly blended, about 2 minutes on medium speed. Pour the cake batter into the prepared jellyroll pan. Dotdash Meredith Food Studios Bake in the preheated oven until the edges of the cake are light brown but the middle of the cake is still slightly gooey, 15 to 17 minutes. Dotdash Meredith Food Studios Meanwhile, make the crumb topping: Mix brown sugar, cinnamon, vanilla extract, and flour together in a large bowl. Rub in 1 ½ cups butter until the mixture forms medium crumbs. Dotdash Meredith Food Studios Remove cake from the oven, and press about 3/4 of the crumb topping onto the top of the almost-baked cake. Reserve the remaining topping. Dotdash Meredith Food Studios Return cake to the oven, and bake an additional 10 to 12 minutes, until the crumb topping is firm and cake is cooked all the way through. Remove cake from the oven, and sprinkle with remaining crumb topping. Let cake cool to room temperature, and sprinkle with confectioners' sugar. Dotdash Meredith Food Studios Cook’s Note There will be a lot of crumb topping — just cut amounts back if it's too much.You can use a 13x9-inch dish if you prefer and increase the first cooking time from 15 to 17 minutes to 25 to 27 minutes.
