Directions

1. Preheat oven to 350°. Spray muffin cups with cooking spray or line with paper liners.
2. Beat sugar, butter, flax seed, vanilla and eggs together in a bowl with an electric mixer until smooth and creamy.
3. Sift flour, salt and baking soda together in a separate bowl. Mix creamed sugar mixture, 1/2 cup at a time, into the flour mixture until fully incorporated and batter is stiff.
4. Beat bananas into batter with an electric mixer on low. Fold chocolate chips and walnuts into batter. Spoon into the prepared muffin cups, filling each cup 3/4 full.
5. Bake in the preheated oven until a toothpick inserted in the center of a muffin comes out clean, about 25 minutes. Cool in the tins for 10 minutes before removing to cool completely on a wire rack.
