HEAT oven to 350°F. Coat three 9-inch round cake pans with baking spray.
BEAT eggs, mashed bananas, water, oil and vanilla in large bowl with electric mixer until blended. Add pancake mixes, pudding mix and brown sugar. Beat 1 minute or until smooth. Divide evenly in prepared cake pans.
BAKE 20 to 22 minutes or until toothpick inserted in center comes out clean. Cool 5 minutes. Remove cakes from pans to wire rack to cool completely.
For Cafe Latte Frosting: STIR frosting in medium bowl until smooth. Dissolve coffee crystals and water in small bowl. Stir into frosting until completely blended.
PLACE one cake layer on serving plate. Spread with 1/2 cup frosting. Repeat with second layer. Place third layer on top. Spread sides and top with remaining frosting. Sprinkle mini chocolate chips along top edge of cake.
TIP * Two cans of frosting are needed to have the 2 1/2 cups frosting for the recipe, using about 1 1/2 cans.
