This is a yummy recipe I got from Family Fun's website. They say the muffins freeze well wrapped in foil and then reheated in the microwave for 30 seconds once unwrapped. I wasn't sure ours would last long enough to freeze but I did get some frozen and they reheated very well!!
1 1/2 cups flour
1 cup whole wheat flour
2 teaspoons baking powder
1 teaspoon baking soda
1/2 teaspoon salt
3 ripe bananas
1/2 cup milk
1 teaspoon vanilla
3/4 cup butter, at room temperature
1/2 cup sugar
1/2 cup brown sugar
1 cup mini chocolate chips
Heat the oven to 375 degrees. Line 18-24 muffin wells with paper liners. (I prefer foil liners when I can find them.)
In a medium-size bowl, whisk together both flours, the baking powder, baking soda, and salt. In another bowl, mash the bananas, then stir in the milk and vanilla until well blended.
In large mixing bowl, beat together butter and sugars until light and fluffy, about 3 minutes. Beat in the eggs one at a time, mixing well after each. Reduce the mixer's speed and blend in one third of the flour mixture followed by half the banana mixture. Continue alternating between flour and banana mixtures, until all ingredients have been incorporated into the batter. Fold in chocolate chips.
Dive the batter evenly among the muffin cups. Bake for 25 minutes, or until a toothpick inserted into the center comes out clean.
Let the muffins cool in the pan for ten minutes, then transfer to a wire rack to cool completely.
