Coffee Cake Baked Oatmeal

A coffee cake-inspired baked oatmeal with notes of cinnamon and nutmeg and topped with an oat pecan crumb streusel. It’s perfectly sweet and perfectly satisfying.

Who says you can’t have coffee cake in baked oatmeal form? No one ever. Let’s just say I was inspired by my very strong sweet tooth in the morning to make this oatmeal.

Growing up, my grandparents would always have a daily morning ritual of making oatmeal. They would cook it with a bit of water in the microwave and top it off with a sprinkle of brown sugar and a glug of milk. I think that is how my obsession with oatmeal began. I mean, what 5-year old loves a bowl of mushy, brown stuff? Me apparently.

As time went on I have been introduced to many more delicious oatmeal combinations. This morning, I was inspired to make a new one: coffee cake baked oatmeal.

The oatmeal base starts with a mashed banana, non-dairy milk, vanilla extract, and maple syrup. Then rolled oats, cinnamon, nutmeg, salt, and baking powder are added.

To top it all off before transferring to the oven is an oat pecan crumb streusel consisting of: pecans, oats, coconut flour, cinnamon, coconut oil, and coconut sugar.

The oatmeal is then baked for 28-30 minutes until golden brown and the kitchen smells like cinnamon rolls.

Optional: drizzle with a simple powdered sugar icing!

Course: Breakfast
Keyword: coffee cake baked oatmeal, gluten-free, vegan
Servings: 9 servings
Author: Taavi Moore
  • 1 medium ripe banana
  • 2 cups non-dairy milk
  • ¼ cup maple syrup
  • 1 tsp vanilla extract
  • 2 ½ cups old-fashioned rolled oats
  • ½ tsp baking powder
  • 1 tsp cinnamon
  • ¼ tsp nutmeg
  • ¼ tsp salt
Pecan Oat Streusel
  • ½ cup whole pecans
  • ¼ cup old-fashioned rolled oats
  • cup brown sugar
  • 1 tbsp all-purpose flour
  • ½ tsp ground cinnamon
  • 4 tbsp melted coconut oil
  1. Preheat oven to 350 degrees. Grease an 8×8 baking dish.

  2. To a large mixing bowl, mash banana until smooth (a few lumps remaining is ok). Whisk in non-dairy milk, maple syrup, and vanilla. Add oats, baking powder, cinnamon, nutmeg, and salt. Use a wooden spoon or spatula to combine until incorporated. Pour mixture into the prepared baking dish and spread to evenly distribute.

  3. To prepare the streusel, add pecans and oats to a high-speed blender or food processor. Blitz until a coarse meal is achieved. Add to a bowl along with the rest of the streusel ingredients. Stir until combined. Mixture should resemble wet sand. Sprinkle streusel over the oatmeal. I didn't end up using all the streusel mixture, so feel free to add as much as you'd like.

  4. Bake for 28-30 minutes until top is golden brown and oatmeal is firm and no longer jiggles. Let cool for 5 minutes before cutting into nine even portions.

      So yummy! I used vegan butter instead of coconut oils and this was delicious.

      I’m curious on how to store it, so you suggest the fridge or Tupperware room temp?

      Can you add protein powder? How would you do that ? Thanks!

      • healthienut
        April 24, 2023 / 4:28 pm

        Definitely! I would recommend 1-2 scoops of vanilla protein powder, you may need a bit more liquid (about ~1/2 cup more).

    I have been making baked oatmeal for 6 years or more. I forgot that I was low on Quick Oats, however, I had a full box of the Old Fashioned Oats. So off to search Pinterest for a recipe that uses Old Fashioned. I was sceptical at first due to no eggs, but who doesn’t love a brown sugar crumb topping I was intrigued and dove in. OMG this came out moist and very flavorful with the cinnamon and nutmeg. I used 1/2 cup frozen pumpkin puree in place of the banana as I’ve yet to try baking with bananas other than quick bread and didn’t want to risk tasting it’s flavor in my baked oatmeal. Due to a slight stroke last July I’m on a specific diet so I used a granulated no calorie sweetener in place of the honey, Splenda Brown Sugar Blend and Whole Wheat flour in the topping along with Avocado Plant Butter. In the oats I added 1.5 Tbls ground flaxseed and the frozen pumpkin puree’s liquid made up the difference for not using honey. This is my new go to baked oats recipe, can’t wait to add chopped apples to the next batch. Thanks for sharing this recipe!
