For Loaves: Mix dry ingredients and wet ingredients in two separate bowls. Gradually add dry ingredients to wet, stirring just until smooth after each addition. Do not over mix. Gently fold in cookie pieces. Divide batter evenly between 2 well-sprayed 9x5-inch loaf pans.
Bake in 350ºF standard oven 1 hour 10 min. or until centers are firm. Cool in pans on wire rack 20 min. Remove loaves from pans and cool completely before icing.
For Lemon Icing: Whisk powdered sugar and lemon juice in bowl until smooth. Pour icing evenly over the entire top of each loaf. Immediately sprinkle cookie pieces over cakes. Let icing set before cutting each loaf into 8 slices.
