Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

3 cups rolled oats
¾ cup brown sugar
2 teaspoons ground cinnamon
2 teaspoons baking powder
1 teaspoon salt
1 cup milk
½ cup melted butter
¼ cup maple syrup
2 large eggs
2 teaspoons vanilla extract
¼ cup dried cranberries

Directions

1. Preheat the oven to 350°F (175°C). Lightly grease an 8×8-inch baking dish to prevent sticking.
2. In a large mixing bowl, combine the rolled oats, brown sugar, ground cinnamon, baking powder, and salt. Stir well to distribute the dry ingredients evenly.
3. Add the milk, melted butter, maple syrup, eggs, and vanilla extract to the bowl. Mix thoroughly until the oats are fully coated and the ingredients are well combined.
4. Fold in the dried cranberries, ensuring they are evenly distributed throughout the mixture.
5. Pour the oatmeal mixture into the prepared baking dish and spread it evenly.
6. Place the dish in the preheated oven and bake for about 40 minutes, or until the oatmeal is set and bubbling around the edges.
7. Remove from the oven and allow it to cool slightly before slicing and serving.

FAQs

Can I make baked oatmeal ahead of time?

Yes, baked oatmeal is perfect for meal prep. You can bake it the night before and store it in the refrigerator, then reheat individual portions in the morning.
