Ingredients You’ll Need
Let’s talk about just how delightfully simple these ingredients are! Each item is handpicked for the unique taste, texture, or cozy aroma it brings to the Amish-Style Apple and Cinnamon Baked Oatmeal, transforming everyday staples into something special and crave-worthy.
- Old-fashioned rolled oats: The foundation of our oatmeal; they bake up fluffy yet slightly chewy, providing just the right bite.
- Brown sugar (or coconut sugar): Adds deep, caramel-like sweetness for that classic breakfast comfort.
- Baking powder: Gives the baked oatmeal a gentle lift, preventing it from being dense.
- Ground cinnamon: Essential for a warm, fragrant aroma and rich, spicy flavor that pairs perfectly with apples.
- Salt: Balances the sweetness and lifts all the other flavors beautifully.
- Chopped walnuts (optional): Bring a crunchy texture and a nutty richness—totally optional, but highly recommended!
- Milk: Adds moisture and helps bind everything together; use dairy or plant-based to suit your needs.
- Large eggs: Hold the oatmeal together, making those lovely, firm, cake-like squares when baked.
- Unsalted butter (melted and slightly cooled): Adds richness, flavor, and a bit of decadence to every bite.
- Vanilla extract: Gives a cozy, bakery-style aroma and a lovely roundness of flavor.
- Medium apples (peeled, cored, and diced): Juicy, sweet-tart apple chunks that soften up as they bake, making every bite burst with autumn goodness.
How to Make Amish-Style Apple and Cinnamon Baked Oatmeal
Step 1: Prep Your Baking Dish and Oven
Start by preheating your oven to 350°F (175°C). Take a moment to generously grease an 8×8-inch baking dish; whether you use butter or nonstick spray, this ensures that gorgeous, golden baked oatmeal will slide right out and slice up neatly later on.
Step 2: Mix Up the Dry Ingredients
In a large mixing bowl, combine your rolled oats, brown sugar, baking powder, ground cinnamon, salt, and walnuts if you’re adding them. Mixing the dry ingredients together first means those flavors will be perfectly distributed throughout the Amish-Style Apple and Cinnamon Baked Oatmeal, with pops of crunch in every bite if you’ve opted for nuts.
Step 3: Whisk the Wet Ingredients
In a separate bowl, whisk the milk, eggs, melted butter, and vanilla extract until fully combined. The butter adds richness, while the eggs help everything bind together for that lovely oatmeal-cake texture. It only takes a minute, but this step is key for even mixing later!
Step 4: Bring It All Together
Pour the wet mixture over the dry oat mixture and stir gently, making sure to moisten everything without over-mixing. Now, gently fold in the diced apples—this keeps them from sinking or turning mushy, and ensures there’s a little apple in every bite of your Amish-Style Apple and Cinnamon Baked Oatmeal.
Step 5: Bake Until Perfect
Pour the oatmeal mixture into your prepared baking dish and spread it out evenly. Pop it into the oven and bake for 35 to 40 minutes, or until the center is set and the top is just golden. You’ll know it’s ready when your kitchen smells like the coziest countryside bakery!
Step 6: Let It Cool and Serve
Let your finished Amish-Style Apple and Cinnamon Baked Oatmeal cool for a few minutes before serving. This little pause lets it firm up for perfect squares (and keeps your tongue from being burnt by molten apple bits).
How to Serve Amish-Style Apple and Cinnamon Baked Oatmeal

Garnishes
A warm square of baked oatmeal positively begs to be finished with a splash of milk, a scoop of creamy yogurt, or a drizzle of pure maple syrup. Try a sprinkle of cinnamon or a little handful of crunchy walnuts on top for extra flair—it’s all about that finishing touch!
Side Dishes
Pair your Amish-Style Apple and Cinnamon Baked Oatmeal with fresh fruit, crispy bacon, or a steaming mug of tea or coffee to make breakfast a true event. For something extra lovely, serve with a side of mixed berries or a dollop of whipped cream for a special treat.
Creative Ways to Present
For fun gatherings or make-ahead breakfasts, cut the oatmeal into bite-sized bars and pack them for a portable snack. Or, layer warm chunks into parfait glasses with thick Greek yogurt and a sprinkle of granola for a show-stopping brunch presentation.
Make Ahead and Storage
Storing Leftovers
Leftovers of Amish-Style Apple and Cinnamon Baked Oatmeal are a true breakfast gift. Simply wrap the cooled oatmeal tightly or transfer to an airtight container; it will stay fresh in the fridge for up to 5 days and tastes just as delicious the next morning.
Freezing
Baked oatmeal freezes beautifully! Slice cooled oatmeal into portions, wrap each square in plastic wrap, and store in a freezer bag for up to 2 months. When you’re ready to enjoy, just thaw overnight in the refrigerator so it tastes freshly baked.
Reheating
To reheat, simply microwave individual squares for 30 to 45 seconds until heated through, or place several wedges of baked oatmeal in a covered dish and warm in a 300°F oven for about 10 minutes. Add a splash of milk before reheating to revive that just-baked creaminess!
FAQs
Can I make Amish-Style Apple and Cinnamon Baked Oatmeal with steel-cut oats?
Steel-cut oats require much longer to cook and more liquid, so this recipe is best suited for old-fashioned rolled oats for that perfect tender texture. If you’re craving steel-cut oats, look for a specifically adapted baked oatmeal recipe!
What’s the best apple variety to use?
Almost any firm, slightly tart apple works beautifully in this recipe—Honeycrisp, Granny Smith, or Fuji all hold their shape and add bright, fresh flavor to the Amish-Style Apple and Cinnamon Baked Oatmeal.
Can I make this recipe vegan or dairy-free?
Absolutely! Substitute almond or oat milk for dairy, use coconut oil in place of butter, and swap flax “eggs” in for real eggs for a fully plant-based version. You’ll still get that cozy aroma and texture!
Is it okay to assemble baked oatmeal the night before?
Yes, you can mix everything together (except for the apples, which you might want to add last-minute to avoid browning) and refrigerate overnight. Pop it in the oven in the morning for extra-easy meal prep.
Can I add other fruit or mix-ins?
Definitely! Dried cranberries, raisins, blueberries, or even a handful of dark chocolate chips all work well. This Amish-Style Apple and Cinnamon Baked Oatmeal is endlessly customizable—just keep the proportions fairly consistent.
Final Thoughts
Don’t let another cozy morning pass you by without giving this Amish-Style Apple and Cinnamon Baked Oatmeal a try. The scent alone will win hearts, and those warm, apple-studded squares just might become your new breakfast favorite! Gather your ingredients, share it with friends or family, and savor every bite.
