Heat oven to 350°F. Lightly grease or spray 8-cavity mini loaf pan with non-stick cooking spray.
For cakes: Whisk together all dry ingredients. Stir in oil, eggs and pineapple until combined. Mash the bananas and add to batter. Stir in pecans.
Divide batter evenly into prepared pans. Bake 25-30 minutes or until a toothpick inserted into center comes out clean.
Cool loaves in pan on a wire rack for 10 minutes. Invert loaves onto wire rack and cool completely, about an hour.
For glaze: beat cream cheese until smooth. Add vanilla and 2 tablespoons milk. Mix until smooth. Add glaze mix and blend until fully combined. If glaze is too thick, thin with an additional tablespoon milk.
Place glaze in plastic baggie and seal. Snip off one corner and pipe glaze over covered loaves.
