Cookies and Cream Zucchini Protein Oatmeal Bake is a delicious healthy breakfast, snack or dessert option you can prep for ahead of time to make breakfast EASY for the week!

IS ZUCCHINI BAKED IN OATMEAL GOOD?

Absolutely! You can’t taste the zucchini one bit! The zucchini is just there to provide volume. But all you are left tasting is delicious, teeth-sinkable, oreo cookie flavored baked oatmeal topped with the most luscious vanilla creme frosting on top!

If the combo sounds odd to you, maybe try envisioning zucchini bread instead. It’s the same idea! Not only does the addition of the zucchini to the oats provide moisture, making the texture amazing, but the zucchini also packs a ton of volume into this dish. Meaning more food for less calories. Which is always a win, am I right?

The vanilla creme frosting is the icing on the cake here. While the chocolate Oreo cookie flavored oatmeal bake is good on it’s own, it’s definitely 10x better with something on top of them! Sometimes I will leave the frosting off and just top with peanut butter and that is delicious too. Or even just a dollop of yogurt and some fresh berries! I provided the macros for both, that way you can decide! I will say, the vanilla creme frosting is super tasty, and definitely a good choice if you are looking to get more protein in.

INGREDIENTS FOR COOKIES AND CREAM ZUCCHINI PROTEIN OATMEAL BAKE

  • Zucchini
  • Quick oats – you can sub for old-fashion oats if you prefer a more heartier texture!
  • Pumpkin
  • Egg whites
  • Protein powder – I used PEScience Frosted Chocolate Cupcake (You can save 10% on PEScience products with my affiliate code LaurenFitFoodie)
  • Granulated sweetener – I used Swerve
  • Sugar-free chocolate jello pudding mix
  • Butter or vanilla extract
  • Black cocoa powder – I love using Wincrest black cocoa or HIIT Nutrition Jet Black Cocoa.
    **NOTE: black cocoa is different than normal cocoa powder. This is what gives it the “cookies and cream” flavor.

HOW TO MAKE COOKIES AND CREAM ZUCCHINI PROTEIN OATMEAL BAKE

  1. Preheat oven to 350 °F. Spray a 9×13″ baking pan with cooking spray and/or line with parchment paper and set aside.
  2. Combine all the ingredients, except the oats, in a food processor or high powered blender. Once combined, stir in the oats. Pour batter into the prepared baking dish.
  3. Bake for 45 minutes to an hour, or until oats have cooked throughout. I have found cooking times to vary for different oven temps, especially for this recipe.
  4. While baked zucchini is baking, you can prepare the frosting. Simply add all ingredients to a medium mixing bowl and stir until combined. You can make the frosting thicker or thinner to your liking by adding less (for thicker) or more (for thinner) water. Keep frosting stored in the fridge until ready to use (this will also allow it to thicken up some more).
  5. The bars will somewhat deflate as they cool. Let cool completely before adding frosting and keep stored in fridge.

INGREDIENTS YOU NEED FOR THE VANILLA CREME FROSTING

  • Plain (or vanilla) nonfat Greek yogurt
  • Coconut flour – I love Bob’s Red Mill, Anthony’s or Viva Naturals.
  • Protein powder – I used PEScience Gourmet Vanilla (You can save 10% on PEScience products with my affiliate code LaurenFitFoodie)
  • Granulated sweetener – I used Swerve
  • Cold water

CAN I LEAVE THE FROSTING OFF?

The frosting is pretty high in protein, so I will admit, there are times I don’t add it just because I already have enough trouble NOT going over my protein goal. It’s SO GOOD. But sometimes I just don’t need the extra protein. I included a MFP entry for both if you decide to omit it!

WHAT TO TOP THIS COOKIES AND CREAM ZUCCHINI PROTEIN OATMEAL BAKE WITH

If you wish to skip the vanilla creme frosting, here are some other frosting ideas you could spread on top:

  • Nut Butter! I LOVE skipping the frosting and just topping with a big ol’ glob of nut butter!
  • Whipped cream cheese – like this one
  • Homemade Healthy Nutella – chocolate on chocolate? This healthy protein packed oatmeal just got REAL fun
  • Oreo Cream Filling – If you’re really into the cookies and cream, this would be another huge level up and for the most part it’s made with the same ingredients (a Greek yogurt base)

And if you want to keep the vanilla creme frosting but are still feeling fancy and want to add a little something else, try one or more of these options:

  • A drizzle of chocolate or caramel sauce
  • Jam – a spoonful of raspberry or strawberry jam would be delicious!!
  • Crumbled up Oreo pie crust – EPIC-NESS. That is what I did for these photos and the added Crunch or REAL Oreo is just marvelous!!
  • Crumbled up Oreo’s – if you’re wanting to go crazy, an even more epic option!
  • Chocolate chips – you can never go wrong with some chocolate chips and this oatmeal bake is no exception!
  • Fruit – I especially love Wymann’s frozen blueberries but fresh fruit is amazing too!

HOW TO STORE COOKIES AND CREAM ZUCCHINI PROTEIN OATMEAL BAKE

Once the oatmeal bake has cooled, cover with a lid or plastic wrap and place in the refrigerator overnight. This will allow the flavors to come out more and bring about a more cookies and cream like flavor. It also helps the bars set so they are more sturdy. Just trust me on this, it’s better the next day!

CAN YOU FREEZE THIS COOKIES AND CREAM ZUCCHINI PROTEIN OATMEAL BAKE?

Yes! If you plan to freeze, let the zucchini oatmeal bake cool, then cut into however many servings you desire. Wrap each bar individually in wax paper or plastic wrap (so they don’t stick together when they’re frozen), then place all the bars in a freezer-safe ziplock bag. I would just freeze the bars, not the frosting, and then just make the frosting when the time comes that you are ready to eat them. The frosting doesn’t hold up as well when frozen and also makes it impossible to reheat really. The bars will stay good in the freezer for 3-4 months.
