Frequently Asked Questions

Can you make baked apple oatmeal the night before?

For an easy breakfast the next day, prep your baked oatmeal the night before and let the oats soak up every drop of that milk mixture all night long. The extra rest will make the oats even softer and more tender. Be sure not to refrigerate for more than approximately 12 hours, as the oats can begin to break down. To bake, just preheat the oven and then bake like normal!

What’s the difference between baked oats and oatmeal?

Both baked oats and oatmeal are two different ways to enjoy rolled oats as part of a wholesome breakfast. Your classic bowl of oatmeal is typically made by cooking rolled oats with water or milk, spices, and brown sugar on the stovetop until tender and creamy. Baked oatmeal is slightly different as it usually includes eggs, melted butter, and baking powder. Then, it’s baked in the oven until it has a light, fluffy cake-like texture and crunchy golden brown crust.

Can you make vegan apple baked oatmeal?

Absolutely! It’s so easy to use almond milk or coconut milk instead of cow’s milk, and you can easily replace the butter with melted coconut oil. Instead of chicken eggs, use flax eggs for the perfect rise.
