A cross between traditional apple crisp and more cake-like apple crumb bars, this dessert will meet your cravings for a luscious fall treat. A tart, firm apple like a Granny Smith provides the best combination of taste and texture, but the recipe can be made with whatever fruit you have on hand. Pears or berries would also work wonderfully in this simple, flexible recipe.

1/2 tsp. cinnamon
1/4 tsp. nutmeg
3 Tbsp. canola oil
1/4 cup apple-juice concentrate, thawed
