  • Vegetable oil spray for coating the pan
  • Flour for dusting the pan
  • 1 cup mashed bananas from 2 or 3 very ripe bananas
  • 1 package (18.25 ounces) plain yellow cake mix
  • 2 tablespoons flour (optional)
  • 1/2 cup vegetable oil
  • 3/4 cup plain or vanilla non-fat Greek yogurt
  • 4 large eggs
  • 2 teaspoons pure vanilla extract
  • 1 cup (6 ounces) miniature chocolate chips
  • 2 teaspoon confectioners' sugar, for dusting on top


  • Position an a rack in the center of the oven and preheat oven to 350F degrees. Lightly mist a bundt pan with vegetable oil spray. Dust with flour, shake out the excess flour and set the pan aside.
  • In a large mixing bowl, combine the mashed bananas, cake mix, flour (if using), oil, yogurt, eggs and vanilla.
  • Beat with an electric mixer on low speed until the ingredients are incorporated, about 30 seconds.
  • Stop the mixer and scrape down the sides of the bowl with a rubber spatula. Beat on medium speed until the mixture lightens and is smooth, about 1-1/2 minutes longer.
  • Stir in the chocolate chips.
  • Pour the batter into the prepared cake pan. Smooth out the top with a rubber spatula.
  • Bake the cake until is deeply golden brown on top and the top springs back when lightly pressed with your finger, 50 to 55 minutes.
  • Remove the cake from the oven and let it cool on a wire rack for 10 minutes. Run a long sharp knife along the edges of the pan. Shake the pan to loosen the cake and then invert it onto the rack.
  • While the cake is still warm, sift the confectioners sugar over the top so that it melts to form a glaze.
  • Let the cake cool for 20 minutes, then slice and serve while still a little warm.

Recipe Notes

I made a few changes to the original recipe to lighten it up and make it a little more Weight Watchers friendly.
I omitted the additional 1/4 cup of sugar called for since cake mixes are plenty sweet for us. Replaced the sour cream with plain non-fat Greek yogurt and increased it by 1/4 cup and decreased the oil by 1/4 cup.
I also added 2 tablespoons of flour which is a trick my mother learned from her Home Economics teacher decades ago to help cake mix cakes be less crumbly.
