Ingredients
- 1-1/2 cups graham cracker crumbs (see Note)
- ¾ cup packed brown sugar
- ¾ cup chopped pecans
- 2 teaspoons ground cinnamon
- ⅔ cup butter, melted
- 1 (15.25-oz) package yellow cake mix (and ingredients called for on the package such as eggs and oil)
- 1 cup powdered sugar
- 1 tablespoon milk
- Preheat the oven to 350 degrees and grease a 9x13 baking pan.
- In a small bowl, combine the graham cracker crumbs, brown sugar, pecans and cinnamon. Stir in butter; set aside.
- Prepare cake mix according to package directions.
- Pour half of the batter into a greased 13-in. x 9-in. baking pan. Bake for 5 minutes so that the streusel doesn't sink to the bottom. Remove from the oven and sprinkle with half of the graham cracker mixture.
- Carefully spoon the remaining batter on top. This is tricky but it's very forgiving. Sprinkle with the remaining graham cracker mixture.
- Bake at 350° for 25-35 more minutes or until a toothpick inserted near the center comes out clean. Cool on a wire rack.
- For the glaze: combine powdered sugar and milk; add more milk 1 tablespoon at a time to desired consistency. Drizzle over cooled coffee cake.
