I made healthy "Twinkies" last week. My husband had bought me a canoe pan a while ago.

As you can see, this is where I got the shape for the Twinkies. I also made some in regular cupcake pans. I made a healthy version using hard white wheat flour. I found another recipe here that I might try next time. http://www.simplemathbakery.com/blog/2010/02/05/homemade-twinkies
Preheat the oven to 350°
Have all ingredients at room temperature.
In the bowl of an electric mixer, beat at high speed until fluffy:
1 1/2 sticks unsalted butter
1 1/4 cups palm sugar
Add slowly and beat on medium speed until fluffy:
3 large eggs
1 teaspoon vanilla extract
In a bowl, sift together:
2 1/2 cups hard wheat white flour
2 teaspoons baking powder
1/2 teaspoon salt
At low speed, add the dry ingredients to the butter and egg mixture alternately with:
3/4 cup milk (do not ever use low fat milk to bake with, the fat makes the baked goods taste better)
Fill each mold or liner three-quarters full. Bake for 18-20 minutes, or until golden. The tops should spring back when lightly pressed. Cool on a wire rack for 5-10 minutes before removing the cupcakes from their pans or before turning the cakes out of their pans.
Since the canoe pan only makes 8 at a time, I made some of them in the cupcake pan.
