How to Make It
Preheat oven to 350°.
To prepare the banana bread, lightly spoon flour into dry measuring cups, and level with a knife. Combine flour, baking soda, and salt, stirring with a whisk to combine.
Place granulated sugar and butter in a large bowl, and beat with a mixer at medium speed until mixture is well blended (about 1 minute). Add mashed banana, egg substitute, sour cream, and vanilla; beat until blended. Add flour mixture; beat at low speed just until moist. Gently fold in blueberries and lemon rind. Spoon batter into an 8 1/2 x 4 1/2-inch loaf pan coated with cooking spray. Bake at 350° for 1 hour and 15 minutes or until a wooden pick inserted in center comes out clean. Cool the bread 10 minutes in pan on a wire rack; remove the bread from pan. Cool completely on wire rack.
To prepare glaze, combine cream cheese, powdered sugar, lemon juice, and water, stirring with a whisk until smooth. Drizzle the glaze over cooled bread.
