You’ll find making this recipe simple if you follow my step-by-step instructions.
Preheat and Prepare
Start by preheating your oven to 350°F (180°C) and lightly grease a 9×9-inch baking pan with cooking spray to prevent sticking.
Mix Dry Ingredients
In a large bowl, combine the oats, baking powder, cinnamon, salt, and chopped pecans. Give it a quick stir to mix everything evenly.
Whisk the Wet Ingredients
In a medium bowl, whisk together the eggs, milk, maple syrup, and vanilla extract. This will be the base that binds the baked oatmeal together.
Combine Everything
Pour the wet ingredients over the oat mixture. Add the melted butter (or you can use coconut oil) and most of the frozen berries, saving a few to sprinkle on top. Gently fold everything together until well combined.
Transfer to the Baking Dish
Pour the mixture into your prepared baking dish, smoothing the top with a spatula. Scatter the reserved berries over the surface for a pop of color.
Bake
Bake the oatmeal uncovered in the preheated oven for 40-45 minutes or until it’s golden brown and the edges are set.
If you like a little extra sweetness, sprinkle some brown sugar over the top before baking.
Cool and Serve
Let the baked oatmeal cool for about 5 minutes before cutting into it. Serve warm, topped with a dollop of Greek yogurt or a swirl of whipped cream for an extra touch.

Notes
- Oats: Use rolled oats instead of quick oats, or you’ll get a mushy texture. If you want to go gluten-free, use certified gluten-free oats.
- Use Fresh or Frozen Berries: Frozen berries are great here because they add moisture as they bake, but fresh berries work just as well if you have them.
- Don’t Skip the Butter: The melted butter adds richness and moisture, so don’t be tempted to leave it out.
- Room Temperature Ingredients: Using room temperature eggs and milk helps everything mix together more smoothly.
- Brown Sugar Topping: Sprinkling a little brown sugar on top before baking gives the oatmeal a sweet, crunchy finish.
- Let It Rest: Allow the baked oatmeal to cool for a few minutes before serving so it has a chance to set.
- Customize It: Feel free to swap out the pecans for walnuts or almonds; most nuts work great. Or use a different type of fruit if you prefer. I love to add strawberries or blackberries. Add coconut, banana slices, or chocolate chips. You can really customize to suit your taste.
