1 box yellow cake mix
2/3 c. buttermilk
1/4 tsp. baking soda
1/2 c. (1 stick) butter, melted and cooled slightly
3 eggs
3 med. size, very ripe bananas, mashed
2/3 c. miniature marshmallows, divided
2/3 c. chocolate syrup, divided
1 c. chopped nuts, divided
2 med. size just-ripe bananas

Beat the cake mix, buttermilk in which the baking soda has been dissolved, the 3 mashed bananas, butter and eggs together for 2 minutes at medium speed.

Grease a Bundt pan generously and coat the sides and bottom with 1/3 cup of the chopped nuts. Spoon 1/3 of the batter carefully over the nuts on the bottom of the pan. Now slice 1 banana very thinly over the batter in the pan.

Sprinkle 1/3 cup of the marshmallows and 1/3 cup of the chopped nuts over the banana slices. Drizzle 1/3 cup of the chocolate syrup over all. Spoon another 1/3 of the batter over this layer, then repeat the process (sliced banana, marshmallows, nuts, syrup). Spoon the remaining 1/3 of the batter over all.

Bake in a preheated 325 degree oven for 75 minutes, or until a toothpick inserted in the center comes out clean. Remove from oven and let set until cool. Sprinkle with confectioners sugar, if desired. Serves 12.
