Author Notes: Very lightly adapted from Super Natural Every Day. Heidi Swanson recommends blueberries or huckleberries or a mix. I've had good luck with just about every sort of berry; I've also used frozen, without incident. And for the record, I've added slightly more nuts here, for extra crunch.Nicholas Day

Serves 6

  • 2 cups rolled oats
  • 1 cup walnuts, toasted and chopped
  • 1 teaspoon baking powder
  • 1 1/2 teaspoons cinnamon
  • 1/2 teaspoon fine-grain salt
  • 2 cups milk
  • 1/3 cup maple syrup
  • 1 large egg
  • 3 tablespoons unsalted butter, melted and cooled slightly
  • 2 teaspoons vanilla extract
  • 2 bananas, sliced into 1/2-inch pieces
  • 1 1/2 cups blueberries or a mix of berries
  1. Preheat the oven to 375 degrees. Butter the inside of a square 8-inch baking dish.
  2. In a bowl, combine the oats, half of the walnuts, the baking powder, cinnamon, and salt.
  3. In another bowl, whisk together the maple syrup, the milk, egg, half of the butter, and the vanilla.
  4. Spread a single layer of bananas across the bottom of the buttered baking dish. Sprinkle about two-thirds of the berries on top. Cover all that with the oat mixture and then drizzle the milk mixture over the oats. Scatter the remaining berries and walnuts over the top.
  5. Bake for 35 to 45 minutes, until the top is golden and the oats are set. Let cool for a few minutes. Drizzle with the remaining melted butter and serve.

OK to use frozen berries?

Trying this this morning! Had to use a 9x13 pan at a lack of 8 inch. Used half almond milk, half applesauce, bananas and peaches on the bottom, almonds, didn't have vanilla, and topped with sliced peaches, coated with lemon juice and brown sugar! We shall see how it turns out!

Love this recipe! It is so versatile and makes great breakfast leftovers. I mix in whatever I have on hand. This time I used pears and blueberries and changed the spices to 1tsp cinnamon, 1/4 tsp.ground cloves, and 1/4 tsp. ground ginger. Yum!

I might have missed it, but do you have to nutritional values?

To all asking what kind of fruit to sub for bananas. I have used peaches in place of "nana's". Blueberries and peaches make a wonderful pairing. Be sure to use ripe but FIRM peaches, cut into small pieces. Hope this works for everyone.

this was so good! I made it with 1 and 1/2 cup of lactose free milk, no butter, 1/4 of cup of maple syrup, blackberries, almonds and bananas. So yummy! Mine turned out like a really soft cookie consistency.

Great recipe! Thanks...

This sounds great . Is it like soft like a breakfast cereal? I would prefer a firmer, soft cookie-like result. Is there a way to adapt it

Could this be done in the crockpot overnight? This is how we cook our steel cut oatmeal.

Ok, don't anyone flame me, but, I gotta ask - has anyone tried with with Splenda? I've got to make things sugar free and lower carb, so the irish oats, high protein milk (thank you HEB) and plenty of nuts are OK, but syrup or honey would hit my blood stream too fast.

Also, can you mix the whole thing up and store in the fridge overnight and bake in the AM? I had to quit caffeine and Am's are still a struggle for functionality.

I sometimes use apple juice or apple sauce as a sweetener. You can probably try upping the noonies which can be terribly sweet as it is and just skip the sweeteners. I have soaked steel cut oats in milk/ spices/ egg combo overnight and added the rest in the morning and baked it then.

I use agave nectar instead of maple syrup. It enters the blood stream at a much slower rate. I never use sugar substitutes....if I can't substitute with the agave I just do without the sugar. If you use agave make sure you use less than the recipe calls for....agave is much sweeter than sugar. Hope this helps!

Delicious, but it was a bit runny.... Will try again :-)

Just made this! Divine! Used 1/2 c steel cut oats, apple juice as sweetener, and soy milk as these were what I had on hand. Yummy.

Love this oatmeal. Such a treat and better with peaches at the bottom than banana in the summer.


over 1 year ago bergamotdreams

Racking my brain- is there any reason why this is once baked it can't be defrosted? I know if one waits too long with bananas they end up as mush, but they are going in the freezer already baked! Anyone?


over 1 year ago Nora-Leah S.

i made this with peaches and no bananas and raspberries. can't wait to try this when it cools.


over 1 year ago Nora-Leah S.

also used almond milk. came out great. won't ever want 'regular' oatmeal after this.


over 1 year ago gustus

Any make-ahead tips? Could this all be mixed and then refrigerated overnight for baking the next morning, or would that interfere with how the oatmeal absorbs the liquids?


over 1 year ago gustus

I ended up toasting the nuts and blending the dry ingredients the night before, then finishing in the morning. Wonderful! Oatmeal is usually my cold-season breakfast, but this dish is a treat in any season.

This made me laugh and made me hungry.


over 1 year ago heiddmeister

I'm not a banana fan either. What else could I substitute, peaches?


over 1 year ago savvynewyorker

Looks REALLY good, but 375 oven for 45+ minutes? Looks more like a awinter breakfast to me!


over 1 year ago Willownest

Could I use steel cut (Irish Oatmeal) instead of rolled??? So much healthier.....
