I love to make this vegan baked apple oatmeal in the Fall and throughout the Winter. Apples are in season and a cozy breakfast of hot oats is perfect when it's cold and rainy outside.

For more delicious baked apple recipes, try German baked apples, an impressive apple frangipane tart, authentic German apple strudel, and German apple pie.

Usually I enjoy my oatmeal by soaking it in boiling water for a few minutes to soften it into a creamy, chewy breakfast. But every now and then, I like to take the extra time to mix oats with peanut butter, milk, honey or maple syrup, baking powder and a few key seasonings.

Vegan baked apple oatmeal takes longer to make than on the stove top, but the prep time is about the same. You could start the oatmeal in the oven while you're getting ready for the day, and by the time you're done, breakfast is ready!

Ingredients and Substitutions

Olive oil - Or substitute melted coconut oil.
Nut butter - I usually use peanut butter, but feel free to use any nut butter or seed butter that you prefer.
Maple syrup - If you're not vegan, you can substitute honey.
Dairy free milk - I usually use oat milk or almond milk.
Baking powder
Ground cinnamon
Salt
Rolled oats - I've also tested this recipe with quick cooking oats, and it still tastes great, but the texture is more crumbly.
Chopped nuts - The optional nuts add a crunchy texture. You can use any nuts like peanuts, hazelnuts, walnuts, almonds, or pistachios.
Apple - Some of the best apples for baking include Honeycrisp, Golden Delicious, Jonagold, and Granny Smith.
