How to Make Amish Baked Oatmeal
Start by preheating your oven to 350F. Grease an 8×8 inch baking dish with butter or nonstick spray.
In a large bowl, whisk together the oats, brown sugar, baking powder, cinnamon, and salt. Break up any clumps of brown sugar with your fingers. In a separate bowl, whisk the eggs, milk, melted butter, and vanilla until smooth. Pour the wet ingredients into the dry mixture and stir until just combined. Fold in the nuts and raisins if you are using them. Pour the batter into your prepared dish and spread it evenly.

Step 1: Mix the Dry Ingredients
Whisk the oats, brown sugar, baking powder, cinnamon, and salt together in a large bowl. Make sure the baking powder is evenly distributed so the oatmeal rises a little as it bakes.
Step 2: Combine the Wet Ingredients
In a smaller bowl, beat the eggs, then whisk in the milk, melted butter, and vanilla. Pour this into the dry mix and stir until everything is wet. Do not overmix. A few lumps are fine.
Step 3: Add Mix Ins and Bake
Fold in your nuts or dried fruit if you want them. Pour the mixture into the greased dish. Bake for 25 to 30 minutes. The top should be golden and the center should feel firm when you gently shake the dish. Let it cool for 5 minutes before serving. This oatmeal tastes incredible with a splash of warm milk poured right over the top, much like how a Moroccan chicken tagine is best with a little sauce spooned on at the table.

Tips for Perfect Amish Baked Oatmeal
Use old fashioned oats
Quick oats turn this into mush. Steel cut oats will stay too crunchy. Old fashioned rolled oats give you that perfect soft but chewy texture that makes this dish so satisfying.
Let it rest before serving
I know it is hard to wait, but letting the dish sit for 5 minutes after it comes out of the oven helps it set up properly. It slices cleaner and the flavors meld together better. If you dig in right away, it will be too loose.
Double it for a crowd
This recipe serves four people generously. If you are feeding a bigger group, just double everything and use a 9×13 inch pan. Bake for about 35 to 40 minutes instead. It works perfectly for brunch, especially alongside a batch of blueberry lemon ricotta pancakes for something fruity on the side.
