15 Delicious Oatmeal Desserts

Sugar-Free Vegan Peanut Butter, Oatmeal and Banana Cookies — Claire Cohen

Oatmeal makes a delicious addition to desserts, thanks to its chewy texture and nutty flavor. When baking with oats, read the recipe carefully. Quick-cooking oats are more processed than those labeled old-fashioned oats, so won't behave the same way in recipes. Steel-cut oats are an even longer-cooking option, so make sure you get the right kind. Try some of these delightful oatmeal dessert recipes for a hearty sweet treat.

Chopped apples give this spiced oatmeal cake a lovely moist texture, while raisins and pecans add a little crunch. Feel free to omit those or swap them for other nuts and dried fruits, if you prefer. The cake doesn't need frosting, but a simple white glaze or dusting of powdered sugar would give it a pretty finish.
