What is baked oatmeal?

Baked oatmeal is oatmeal baked in the oven making breakfast incredibly easy. You can make it ahead so that all you have to do is warm it in the morning, or you can also eat it straight from the fridge (which I often do)! It’s a great simple breakfast or snack option. It tastes like actual dessert and it’s just so delicious!

What you need to make brownie batter baked oatmeal + substitutions:

  • Quick oats- I love using quick oats because it gives it the best texture! This is my absolutely favorite way to make baked oatmeal, it gives it a dense brownie-like. You can substitute with rolled oats, which will make it a little more chewy and still fabulous!! Steel cut won’t work.
  • Cashew milk- You can definitely substitute with almond milk, dairy milk, or whatever milk. I just always have cashew milk.
  • Banana- The mashed banana gives it a little sweetness and makes it moist, for lack of a better word.
  • Cacao powder- To make it brownie batter flavored you have to have some chocolate in there! You can use cacao OR cocoa powder. Up to you!
  • Maple syrup- I prefer maple syrup as my sweetener because it’s my favorite! You could use honey, brown sugar, or coconut sugar as well.
  • Baking powder- Baking powder helps the oatmeal to rise.
  • Vanilla extract- A key to any baked recipe in my opinion.
  • Sea salt- I don’t bake anything without salt. It’s what helps bring the flavor out in a recipe.

Tips for making:

  • Quick oats vs rolled oats- Like I said above, quick oats will give it a denser, more brownie-like texture and is what I prefer. Rolled oats will still work great, but they will just create a more crumbly texture.
  • For the best texture- You want to make sure the mini brownie batter baked oatmeal is still soft in the center but cooked through. That way it comes out nice and soft.
  • For toppings- I topped mine with a Jojo’s Chocolate bite chopped up (we are obsessed with these & you can use the code LEX10 for 10% off their site), but you can also substitute with chocolate chips. I also always love the combo of banana and peanut butter but you do you!

  • 1 tbsp maple syrup
  • ½ tsp baking powder
  • ¼ tsp vanilla extract

  • Preheat oven to 350F degrees.
  • In a small bowl, mash banana.
  • Next, add in the rest of the ingredients: oats, milk, cacao powder, maple syrup, baking powder, cinnamon, vanilla, and sea salt. Mix until well combined.
  • Grease your ramekin (I used a 4.5" diameter & 6 oz. capacity) or any similar size dish. Bake for 25 minutes until the inside is set but still soft. Enjoy warm and top with whatever you like! I did chopped up Jojo's bites (use the code LEX10 for 10% off), or sub with chocolate chips, peanut butter and banana!
  • Also, store in the fridge for 4-5 days and enjoy cold (which I love) or reheat in the morning. Freezing instructions in the notes!


For Storing: Let oatmeal cool completely. Then, cover with plastic wrap or remove from ramekin and store in an airtight container in the fridge for 4-5 days.
For Freezing: To freeze, cool completely. Then wrap in plastic wrap and store in a freezer bag. Lasts in the freezer for up to 3 months.
