INSTRUCTIONS

Step 8:
Leftovers? Wrap them up and pop in the fridge. They'll keep up to a week.
Step 7:
Once it's out of the oven, let it sit for about five minutes. Scoop it up and serve with yogurt if you want.
Step 6:
Bake for about 35 minutes, or go a bit longer if you like it firmer. The middle should look a little wobbly if you want it softer.
Step 5:
Pour everything into your greased pan. Want extra crunch? Sprinkle on those nuts.
Step 4:
Fold those berries in gently so they don’t get smashed.
Step 3:
Drop in the oats, baking powder, cinnamon, and salt. Give it all a good stir.
Step 2:
Grab a big mixing bowl. Whip together the milk, eggs, maple syrup, melted butter, applesauce or banana, and vanilla.

Start by moving your oven rack to the lower part. Heat up your oven to 350°F (177°C). Spray a square baking pan (9×9 or 11×7 inch) with nonstick spray.

Serving and Storage Tips

  • This oatmeal is best served hot, either cut into squares or scooped right into bowls. Top with yogurt or extra maple syrup if you're in the mood.
  • Keep leftovers in the fridge and they'll stay good for one week. Warm up pieces in the microwave for 30 to 60 seconds until nice and hot.
  • Want to freeze extra? Cut the cooled bake into squares, wrap each tight in plastic, and freeze up to three months. Warm from frozen in the oven or microwave.

Helpful Notes

  • Feel free to swap in your favorite fruit. Try apples, banana slices, or peaches if you're after different flavors.
  • Need it dairy-free? Go for almond milk or any milk you like that's not from cows.

Tips from Well-Known Chefs

  • If you like a crunchy sweet top, Jamie Oliver says to sprinkle cinnamon sugar on before baking—it’ll caramelize up nicely.
  • Looking to jazz things up? Yotam Ottolenghi likes adding cardamom or nutmeg for a twist of extra flavor.

  • It's got plenty of oats and fruit, so it's filling and you can make it ahead for grab-and-go mornings.

VARIATIONS
