I made these today and they were fab! I used creme fraiche instead of sour cream.
Banana muffins
3 mashed, very ripe bananas
1/2 cup granulated sugar
1/4 cup vegetable oil
1/2 cup sour cream or yogurt
2 eggs, beaten
3/4 cup whole wheat flour
3/4 cup all-purpose flour
1 tsp baking powder
1 tsp baking soda
1/2 tsp salt
1 cup blueberries (or dried cranberries, chocolate chips, etc.)
In large mixing bowl, combine bananas, sugar, oil, sour cream and eggs; mix thoroughly.
In a separate bowl, mix together flour, baking powder, soda and salt. Add blueberries and stir to coat with flour mixture. Add to banana mixture, mixing until just combined.
Spoon into large muffin cups (lined with paper liners) and bake at 375 for 20-22 minutes. Turn out on to a cooling rack.
These freeze beautifully and can be reheated in the microwave.
Taste Tester Notes: These are easy to make and very moist. I tried these with chocolate chips, and another batch with blueberries. Combined with banana, both flavours were very good. I omitted the sugar in both versions, and found that the natural sweetness of the bananas made them sweet enough for my taste, especially when using chocolate chips. For an even healthier version, use all whole-wheat flour. I made 12 muffins that baked in 18 minutes. (Suggestion: If you have bananas turning brown and can't use them right away, mash them and freeze for baking later.)
