About This Recipe
We are several batches in at my house and there’s no going back — these Brownie Baked Squash Oats are a new staple! They’ve become my favorite afternoon treat. And Sophia’s breakfast and dessert!
I don’t want to trick you, so I need to make my disclaimer. These are not brownies or cake. Brownies and cake need FATS— butter or oil etc. So don’t be expecting crispiness or chewiness or fudginess. All of that takes fat! This is it’s own thing. More of a firm square of chocolate oatmeal… made extra “macro-friendly” since it’s bulked up with squash, and I’m hooked!
Ingredients and Substitutions
- Yellow summer squash or zucchini: Finely grated or riced in a food processor.
- Liquid egg whites: A great way to add extra protein to these oats!
- Old-fashioned oats: Rolled oats or old-fashioned oats are my preference for these baked oats. I love how hearty they are and make this more of a dense cake. You could also use quick oats but they will have a little lighter, fluffier, more cake-like texture. I do not recommend using steel-cut oats.
- Creamer: I love the Califia Farms almond milk creamer or you can just sub your favorite milk.
- Protein powder: Use your favorite chocolate protein powder. I’m LOVING the brownie batter by Clean Simple Eats (Use Lillie for 10% off) or the chocolate protein powder by Active Stacks (Use Lillie for 10% off).
- Stevia: Liquid vanilla stevia or monkfruit. I prefer the liquid version as I think it blends best but any sweetener of choice works!
- Cocoa powder: I love to use jet black cocoa powder (use code Lillie10 for 10% off) to give these oats that really rich, dark chocolatey flavor but you can use any cocoa powder you love!
- Vanilla extract: Adds the perfect amount of sweetness!
- Baking powder: Make sure your baking powder is fresh (less than 3 months old).
- Chocolate chips: I love to use the mini chocolate chips so you get little pools of chocolate in every bite but regular chocolate chips also work.

How to Make Brownie Baked Squash Oats
- Pre-heat oven to 350 degrees.
- Wash and dry your squash and grate them finely. OR, you can use a food processor or salsa maker to “rice” them if you don’t like the strands. OR, use your food processor to get it smooth if you prefer no chunks. (This has become our favorite method.)
- In a large bowl, combine your riced squash (no need to drain), liquid egg whites, oats, creamer, protein powder, stevia, cocoa powder, vanilla, and baking powder. Mix well and pour into a greased 9×9 pan. (**edited from 9×13 because thicker is better!) Sprinkle the top with 2 Tbsp mini chocolate chips and bake for 35-40 minutes or until set. The bottoms will be wet but that’s ok! It gets better as it sits in the fridge. And the cook time does seem to vary a bit with your protein powder. Keep an eye on them!
- Let them cool before cutting into 8 pieces. I love mine chilled, then served in a bowl with cashew milk, a few tablespoons of almond milk Reddi Whip, chopped strawberries, and a few more mini chocolate chips! OR, just some reddi whip, a little drizzle of natural peanut butter, and a pinch of flake salt. We also love them with yogurt and fruit. A perfect breakfast, afternoon snack, or healthy dessert.
- Make sure to store in the refrigerator and enjoy!

How to Serve Your Brownie Baked Squash Oats
They smell like heaven coming out of the oven. BUT, I much prefer my brownie oats chilled in the fridge, then served in a bowl with cashew milk, a few tablespoons of almond milk reddi whip, chopped strawberries, and a few more mini chocolate chips!
I think pouring milk on top weirds some of you out and THAT’S cool. But I grew up eating cake in a bowl with milk poured on top. SO maybe it’s nostalgic, or maybe I’m just letting you in on the best kept secret, arming you with the tools to maximize your baked brownie oat enjoyment. I’ll let you decide.
We also love them with yogurt and fruit. And that’s normal. Or a peanut butter drizzle. A perfect breakfast, afternoon snack, or healthy dessert. You can’t go wrong!

Random question; if I don’t have liquid stevia or monk fruit (just powdered) do I still use 15g or do I need the liquid?
Thanks in advance!
Super easy to meal prep for the week and tastes amazing! Feel is like I’m having a chocolate brownie for breakfast.
So yummy and great macros!
I had 2 squash leftover that I’ve been needing to use, and I love that this recipe uses easy things I already have at home to make good use of them. Thank you!
Absolutely delicious! This recipe is a go-to for me – I eat them at breakfast, for a snack, or even as a healthier dessert. I make them without any sweetener, and they still satisfy my chocolate cravings and fill me up. So thankful for Lillie and her delicious recipes!
am I reading the recipe right… 1 TABLESPOON of liquid vanilla stevia? Or should be a teaspoon? I use stevia a lot but I’ve never used a full tablespoon in a single recipe.
Can this be made using eggs instead of egg whites?
I make this recipe EVERY week. It’s become my favorite nightly dessert!
This is my new favorite mid-morning meal. Definitely best cold. I top mine with frozen sliced banana, a drizzle of natural peanut butter, and a little flake salt. It’s perfection! Thanks for another winning recipe, Lillie!
So delicious! I have been eating this for breakfast 3 weeks in a row. It delicious, filing and satisfies the sweet tooth.
Hi! Can you sub frozen cauliflower for the frozen zucchini?
These are delicious! I know Lillie gave a disclaimer that they aren’t a brownie or cake, but they are such a nice combo, I wasn’t disappointed in the least! I’ve tried them plain, as well as with non-dairy reddi whip, pb, and raspberries. So good! Already planning a double batch!
Yet another recipe I cannot wait to devour every day! I’ve been loving this for either breakfast with some fruit or as a nighttime healthier sweet tooth craving. So so good. I will probably be making this every week for the foreseeable further haha thank you!
I really enjoyed this. It doesn’t take that long to grate the squash, and you can’t taste it. It was a great chocolate flavor and I added bananas and some chocolate almond butter on top. Will definitely rotate between this and the chocolate peanut butter baked oats with riced cauliflower.
I am not going to lie, when I was mixing everything together it didn’t look very appetizing but it TASTED better than I even imagined. HEAVEN
Oh so glad!
