So what makes this coffee cake baked oatmeal healthy? Here’s the shortened version:

Baked Oatmeal Without Eggs or Milk

This oatmeal recipe uses absolutely no eggs or regular milk! Just like in my Matcha Latte recipe, we use plant based milk as listed above. Feel free to use any milk you have on hand though! And even if you don’t have milk, you can sub with good ole’ H2O (water). The oats and protein powder make this oatmeal bake soft, chewy, and slightly fluffy without having to add any eggs. 

How to Make Vegan Coffee Cake Baked Oats

As I just said above, you don’t need any eggs or flax eggs for this baked oatmeal recipe. It’s completely vegan and plant based. The beauty of this oatmeal recipe is that you can use whatever protein powder or milk you have on hand! Even if you don’t have milk, you can sub it for all water. That’s how easy and simple it is!

This high protein baked oatmeal recipe is made with my very favorite unflavored plant based protein powder. And if you’re looking for more great vegan breakfast options, check out these 12 Easy Vegan Protein Breakfasts!

Prep Time 10 minutes
Cook Time 40 minutes
Total Time 50 minutes


Streusel Topping:

  • ⅓ Cup Oat Flour (I make my own in three steps)
  • ½ Cup Rolled Oats
  • 2 Tbs Coconut Sugar
  • 1 tsp Cinnamon
  • Dash Pink Salt
  • 3 Tbs Cubed Cold Grass-fed Butter (can sub vegan butter or solid coconut oil)
  • Optional: ½ Cup Coarsely Chopped Walnuts (or nut of choice)

Optional Maple Cream Cheese Icing

  • ½ Block (4 oz) Low-Fat Cream Cheese (can sub vegan cream cheese) *softened
  • 2 Tbs Grass-Fed Butter (can sub vegan butter) *softened
  • 2 Tbs Pure Maple Syrup (+ more if you like sweeter frosting)
  • 1 tsp Vanilla Extract


1. Preheat the oven to 350 F.

2. In a 2-quart baking pan   add all oatmeal ingredients and stir until mixture is well combined. Set aside while you make the streusel topping.

3. In a medium bowl, combine all streusel ingredients except cold butter and nuts (if using). Mix until well combined. Add in cold cubed butter and use a handheld pastry blender or your hands to combine ingredients until it looks like coarse crumbs. 

4. Cover baked oatmeal with streusel topping and place in the oven to bake at 350 F. for 35-40 minutes until golden brown (mine is perfect after 40 minutes).

5. Optional: While the baked oatmeal is baking, make maple cream cheese icing by combining all ingredients in a medium bowl and beating on high with an electric mixer. You can also do this using a fork, just be patient until you get a very smooth consistency. If glaze is looking clumpy, place in microwave and defrost for 15 seconds and then continue mixing until smooth.

6. Let baked oatmeal cool for a few minutes or until set and serve with maple cream cheese icing, protein cream cheese icing, nut butter, fresh berries, banana slices, or your favorite milk! 

7. Store in the fridge for up to a week and enjoy a premade healthy breakfast all week long!


  1. Liquid: You can use any liquid of choice for this recipe. I use a combination of plain unsweetened almond milk and water to make the oats thick and creamy. You can swap the milk for all water or do a different combination. I have found that this combo works perfectly though!
  2. Most oats are gluten-free, just make sure by checking the packaging! I love this brand.
  3. Any protein powder works! If you’re using flavored or sweetened protein powder, I suggest adding less honey or maple syrup until you get desired taste. Whey protein powder may create a more spongy texture.
