My chart shows a 3" orange is 22 carbs, 3 fiber, net 19 and 1/4 cup fresh pineapple is 6carbs, 1 fiber, 5 net. Canned pineapple should depend on whether sugar is added, etc but my list shows 2 slices of canned pineapple is 15 carbs, 1 fiber, 14 net - I'd check the can. Recipe sounds yummy... I wonder if I can make a one layer cake with half the recipe.
