C.S.
Your question made me think of a muffin recipe I found a while ago that I used to make all the time---Peanut Butter and Banana Muffins. I chose to put carrot puree in them, and they are also made with whole wheat flour, so they're pretty nutritious, and they truly taste so so good.
1 cup firmly packed brown sugar 1 tsp baking powder
1/2 cup peanut butter 1 tsp baking soda
1/2 cup carrot puree 1/2 tsp salt
1/2 cup banana puree
1 large egg white
1 cup whole wheat flour
preheat to 350......coat muffin tin with spray or use paper cups.....in lg mixing bowl, mix brown sugar, peanut butter, carrot and banana, and egg white. put dry ingredients in big plastic bag and shake to mix, then add that to the p.b. mixture and stir. bake them for 15 to 20 minutes.
Makes me wanna go make 'em right now!
