Banana Bundt cake

Oh how my heart longs for this bundt pan. But I've had one like this since I moved out of my parents house 24 years ago. It's chipped and the teflon coating is peeling, which scares me a little, but it still works if I use enough butter and flour. Whenever a recipe calls for a bundt pan you could easily use a 9x13 cake pan. But bundt cakes are so pretty!

1/3 cup butter
1 1/4 cups sugar
2 eggs
1 teaspoon vanilla extract
3 ripe bananas, mashed with a fork
2 cups flour
1 tsp baking powder
1 tsp baking soda
1/2 tsp salt
1 cup plain yogurt (you could probably used flavoured yogurt too or sour cream)
Feel free to throw in a cup or so of chopped nuts or berries.

Beat the butter and sugar until they're creamy. Add the eggs, one at a time, beating well after each addition. Blend in vanilla. Add bananas, flour, baking powder, baking soda and salt, stirring just until combined.
Pour into a greased and floured bundt pan or 9x13 cake pan. Bake at 350 F for 50 minutes or until it's done. Cool a few minutes in the pan before removing to a wire rack to cool completely. Dust with confectioners' sugar before serving.
