Cut iced lemon mini loaf cakes in half then cut into small 1/4 inch cubes.
Mix whipped cream with 1 Tbs pineapple juice and 1 Tbs orange juice to make citrus whipped cream, or leave plain if you'd prefer.
To create parfait, start with a layer of lemon loaf cubes, top with whipped cream, top with a pineapple ring or chopped pineapple, and finish it off with more whipped cream and sprinkles.
For the apple crumble parfaits:
Cut cinnamon crumb mini loaf cakes in half then cut into small 1/4 inch cubes, keeping the bottom half separate from the top crumb half.
To create parfait, start with a layer of the bottom (non-crumb) loaf cubes, add chopped apples, top with the crumb loaf cubes, and finish it off with vanilla ice cream an sprinkles.
