tropical banana cake

Tropical Banana Cake
2 1/2 C. sifted cake flour (you can use regular flour too)
1 2/3 C. sugar
1 1/4 tsp. baking powder
1 tsp. baking soda
1 tsp. salt
2/3 C. shortening
1 1/4 C. mashed banana (about 3)
2/3 C. buttermilk
1/2 C. eggs (about 2)
1 tsp. vanilla
Sift together the following into large bowl: flour, sugar, baking powder, baking soda & salt. Then add shortening, bananas, & 1/3 C. of the buttermilk. Stir to dampen flour mixture. Beat w/mixer for 2 min. Add remaining buttermilk, eggs and vanilla. Beat 2 min. Pour into greased & floured pans (I always use two 9" rounds and I put parchment paper in the bottoms of the pans to ensure no sticking - when you do this, grease the bottom, then lay the parchment paper, then grease and flour the top of the parchment paper). Bake at 350 for 30-35 min.
