Delicious Apple Cinnamon Oatmeal Bake (Printable)

Baked apple-cinnamon oats with fruit and nuts—an easy, make-ahead breakfast that stays moist and warms up nicely.

# What You Need:

→ Dry Ingredients

01 - 2 cups rolled oats
02 - 1/2 cup chopped walnuts or pecans (optional)
03 - 1 teaspoon baking powder
04 - 2 teaspoons ground cinnamon
05 - 1/4 teaspoon ground nutmeg
06 - 1/2 teaspoon salt

→ Wet Ingredients

07 - 2 cups milk (dairy or non-dairy)
08 - 2 large eggs
09 - 1/4 cup unsalted butter, melted (or coconut oil)
10 - 1/3 cup maple syrup or honey
11 - 2 teaspoons vanilla extract

→ Fruit

12 - 2 medium apples, peeled, cored, and diced
13 - 1/3 cup raisins or dried cranberries (optional)

# Steps:

01 - Preheat oven to 350°F (175°C). Generously grease a 9x9-inch baking dish to prevent sticking.
02 - In a large mixing bowl, thoroughly combine rolled oats, chopped nuts, baking powder, ground cinnamon, nutmeg, and salt.
03 - In a separate bowl, vigorously whisk together milk, eggs, melted butter, maple syrup, and vanilla extract until fully incorporated.
04 - Pour the wet ingredients into the dry mixture. Stir gently until evenly moistened and just combined.
05 - Fold diced apples and dried fruit into the oatmeal batter, ensuring even distribution.
06 - Spread the mixture evenly in the prepared baking dish. Place in oven and bake for 35 minutes, or until the top is golden brown and the center is set.
07 - Allow bake to cool for 5 minutes before slicing. Serve warm, optionally topped with extra milk or yogurt.

# Expert Advice:

01 -
  • Your kitchen will smell like a bakery, but there’s zero fuss involved.
  • It’s easy to meal-prep, and each slice tastes even better reheated the next day.
02 -
  • If you skip greasing the dish well, the edges will stubbornly stick and make cleanup a headache.
  • Letting the bake sit for a few minutes before cutting helps it hold its shape—otherwise, it’ll be more like oatmeal soup the first time you scoop.
03 -
  • If you want extra crunch on top, scatter a few nuts and a pinch of raw sugar over the oatmeal before baking.
  • Toss the diced apples with a little cinnamon right before folding them in for deeper flavor.
