Ingredients

  • 5 large (or 6-7 medium) very ripe bananas, sliced
  • 1 cup chopped pecans
  • 1 (12 ounce) can evaporated milk
  • 1 (21 ounce) box Krusteaz Cinnamon Swirl Crumb Cake & Muffin Mix (or see my notes below to sub with yellow or white cake mix)
  • ¾ cup (1 ½ sticks) salted butter, thinly sliced into squares
  • Optional, for serving: vanilla ice cream or whipped cream; additional sliced bananas; additional chopped pecans; caramel sauce; chocolate sauce or hot fudge sauce

Instructions

  • Preheat oven to 350°F. Grease a 9 x 13-inch baking dish or spray with nonstick cooking spray.
  • Arrange the sliced bananas in the bottom of the prepared baking dish. Sprinkle chopped pecans over top.

  • Sprinkle the dry cake mix over the milk; do NOT stir. Top with the bag of cinnamon streusel (or use just ½ - ¾ of the streusel for a slightly less sweet dessert); do NOT stir.

  • Bake, uncovered, for 40-45 minutes or until golden brown. If there are still dry, powdery spots on top of the dessert, just add extra butter in those spots to cover. Return the dish to the oven for 2-3 more minutes.

Notes

    • Instead of the cinnamon crumb cake mix, you can sub with white cake mix, yellow cake mix, or spice cake mix. If you use a 15.25-ounce box of cake mix, reduce the evaporated milk to just 1 cup. You'll also want to sprinkle the bananas with about ¼ cup of cinnamon-sugar, and add another 2 tablespoons (or more) of cinnamon-sugar on top of the dry cake mix (since you won't have a pouch of cinnamon streusel).
    • Swap out the pecans and use chopped walnuts or almonds. Alternatively, you can omit the nuts altogether.
    • Use just half or ¾ of the pouch of cinnamon streusel for a less-sweet dump cake.
