INGREDIENTS
- Optional Toppings: Go for a half cup of chopped walnuts or pecans if you want some crunch.
- Mixed Berries: 1 and 1/2 cups (225g), either fresh or straight from the freezer—don’t bother thawing.
- Salt: 1/4 teaspoon, just enough to stop things from tasting too sweet.
- Vanilla Extract: 1 teaspoon, brings out the flavors in everything else.
- Cinnamon: 1 teaspoon, adds that warm, spicy punch.
- Baking Powder: 1 teaspoon, helps make everything rise a little bit.
- Old-Fashioned Rolled Oats: 3 cups (255g), for that hearty, chewy bite.
- Applesauce or Mashed Banana: 1/4 cup (60g), keeps things moist and boosts the natural sweetness.
- Unsalted Butter: 1/4 cup (56g), melt it and let it cool a little to amp up the moisture and flavor.
- Maple Syrup: 1/2 cup (120ml), for that deliciously sweet kick.
- Eggs: 2 large, these make everything stick together and turn out rich.
- Milk: 1 and 3/4 cups (420ml), pick any kind you want for the creamy base—dairy or plant-based works fine.
INSTRUCTIONS
- Step 8:
- Pop any extras in the fridge by covering them tight. They'll be good for a week.
- Step 7:
- Let it cool five minutes before you dig in. Add some yogurt on top if you’re feeling fancy.
- Step 6:
- Put it in the oven for about 35 minutes. If you want it soft, take it out when the middle looks barely set. Want it firmer? Let it go until it’s solid.
- Step 5:
- Pour everything into your prepped baking dish. Throw some nuts on there if you’d like some crunch.
- Step 4:
- Fold in the berries gently so they don’t get smooshed.
- Step 3:
- Stir in oats, baking powder, cinnamon, and salt until it’s all mixed together.
- Step 2:
- In a big bowl, whisk together the milk, eggs, maple syrup, butter, applesauce or banana, and the vanilla.
- Step 1:
- Move your oven rack low and heat your oven to 350°F (177°C). Prep your baking pan (9×9 or 11×7 inches) with some nonstick spray.
Serving and Storage Tips
- Enjoy your oatmeal hot, either by the slab or scooped straight into a bowl. Great with yogurt on top or a little more maple if you want.
- If you’ve got leftovers, stash them in the fridge—they’ll keep up to a week. To rewarm, just microwave a serving for 30-60 seconds till hot.
- You can freeze slices, too. Once it's cool, cut it up, wrap the pieces, and freeze for as long as three months. Just microwave or pop in the oven right from frozen when you’re ready to eat.
Helpful Notes
- Switch up the flavors with whatever fruit you like best. Try bananas, apples, or peaches for a change.
- Trying to skip the dairy? Any non-dairy milk like almond will work fine here.
Tips from Well-Known Chefs
