Key Ingredients for the Perfect Coffee Cake Baked Oatmeal

One of the best features of this recipe is how it utilizes simple, everyday ingredients you likely already have. We focus on real, whole foods to create a truly nourishing and delicious breakfast.

For the Oatmeal Base:

Gathering the wholesome ingredients for the baked oatmeal base.
  • Old Fashioned Rolled Oats: The star of our recipe! We highly recommend using old-fashioned rolled oats, like Bob’s Red Mill Gluten-Free Rolled Oats, for their chewy texture and ability to absorb moisture without becoming mushy. Quick oats are not ideal as they can lead to a less desirable consistency.
  • Baking Powder: This leavening agent is crucial for giving the baked oatmeal a light, fluffy, and cake-like texture, making it truly reminiscent of coffee cake.
  • Cinnamon: Essential for that signature warm, spicy flavor profile of coffee cake. Don’t skimp on this!
  • Salt: A small pinch enhances all the other flavors, balancing the sweetness and making the cinnamon pop.
  • Flax Seeds, Chia Seeds, or Hemp Seeds (Optional): These are fantastic additions for a boost of omega-3s, fiber, and protein. They also help thicken the oatmeal slightly, adding to its hearty nature.
  • Almond Milk: Our preferred non-dairy milk, but feel free to use any milk you have on hand – cow’s milk, soy milk, or oat milk all work beautifully.
  • Vanilla Extract: A touch of vanilla adds depth and a comforting aroma that perfectly complements the cinnamon.
  • Unsweetened Applesauce: This is a wonderful natural sweetener and a key ingredient for moisture. It also acts as a binder, contributing to the soft, cakey texture. Mashed banana can be used as a substitute, though applesauce gives a milder flavor profile.
  • Real Maple Syrup: Provides a natural, rich sweetness. You can substitute honey or even regular granulated sugar if that’s what you have. For a lower sugar option, feel free to reduce the amount or omit it entirely.

For the Irresistible Crumb Topping:

The simple ingredients for creating that delicious, buttery crumb topping.
  • More Old Fashioned Rolled Oats: These are processed into a coarse flour to create the crumbly texture. If you have oat flour on hand, you can use that directly for convenience.
  • Raw Sugar, Coconut Sugar, or Cane Sugar: Provides the sweet crunch for the topping. For a less sweet version, you can reduce the sugar by half.
  • Cold Butter or Vegan Butter: This is critically important! Using cold butter (or cold vegan butter) is key to achieving a truly crumbly streusel topping. If your butter is at room temperature, it will melt too quickly into the oats during baking, resulting in a less distinct texture (though still tasty!).
  • Cinnamon: Another dose of warm cinnamon in the topping amplifies the coffee cake flavor and aroma, tying everything together beautifully.

Creative Substitutions + Flavorful Additions

One of the beauties of baked oatmeal is its incredible versatility. Don’t be afraid to experiment and make this recipe truly your own! Here are some ideas to customize your Coffee Cake Baked Oatmeal:

  • For Gluten-Free Baked Oatmeal: Always ensure you are using certified gluten-free rolled oats. Brands like Bob’s Red Mill clearly label their gluten-free products, offering peace of mind. If gluten is not a concern for you, any regular old-fashioned rolled oats will work perfectly.
  • For Dairy-Free or Vegan Baked Oatmeal: This recipe is already designed to be dairy-free when using almond milk (or another plant-based milk). For the topping, simply swap out the cold dairy butter for a good quality chilled vegan butter or solid coconut oil. Ensure the coconut oil is firm and cold for the best crumbly texture.
  • Elevate with a Dessert Feel: If you’re truly embracing the “dessert for breakfast” vibe, a decadent drizzle of cream cheese frosting can transform this dish. Try the delicious and healthier cream cheese frosting from our Healthy Carrot Cake Recipe for an extra special touch.
  • Fruity Freshness: To introduce a burst of bright flavor and color, consider adding a cup of fresh or frozen blueberries to the oatmeal mixture before baking. The blueberries will gently burst, creating pockets of fruity goodness and turning it into a delightful Blueberry Coffee Cake Baked Oatmeal. Raspberries or chopped apples would also be wonderful.
  • Nutty Crunch: For added texture and healthy fats, fold in a handful of chopped nuts like walnuts, pecans, or almonds into the oatmeal base. You can also sprinkle them on top with the streusel for an extra crunch.
  • Chocolate Lovers’ Dream: Stir in a quarter cup of chocolate chips or cacao nibs into the oatmeal mixture for a touch of chocolatey indulgence.
  • Spice It Up: Enhance the warm spice profile by adding a pinch of nutmeg or a dash of allspice to the oatmeal or crumb topping alongside the cinnamon.

Step-by-Step Guide to Baked Oatmeal Perfection

Creating this delicious Coffee Cake Baked Oatmeal is a straightforward process that yields impressive results. Follow these simple steps for a perfect breakfast:

Dry ingredients in a square baking dish for baked oats.
Combining the dry ingredients directly in the baking dish.
  1. Prepare Your Oven and Dish: Preheat your oven to a cozy 375°F (190°C). Lightly spray an 8×8-inch baking dish with cooking spray to prevent sticking. In the bottom of this prepared dish, combine your old-fashioned rolled oats, baking powder, cinnamon, salt, and any optional seeds (flax, chia, or hemp). Use a wooden spoon or whisk to mix these dry ingredients thoroughly until well combined.

2. Add Wet Ingredients: Pour in the almond milk, vanilla extract, unsweetened applesauce, and maple syrup directly into the dish with the dry mixture. Stir everything together until the ingredients are just combined and the oats are evenly moistened. Be careful not to overmix.

3. Prepare the Crumb Topping: In a food processor or blender, pulse ⅓ cup of old-fashioned rolled oats until a fine, flour-like consistency is achieved. Then, add the very cold butter (or vegan butter), sugar (raw, coconut, or cane), and cinnamon to the food processor. Pulse a few more times until the mixture is well combined and forms coarse, crumbly pieces. Evenly sprinkle this delicious crumb topping over the prepared baked oatmeal mixture in the dish.

4. Bake to Perfection: Place the baking dish in your preheated oven and bake for approximately 30 minutes. The oatmeal is ready when it is set in the center and the crumb topping has turned a beautiful golden brown and looks crisp. Let it cool slightly before serving to allow it to firm up.

Storage and Meal Prep Tips

This Coffee Cake Baked Oatmeal is incredibly versatile for meal prepping, ensuring you have a healthy and delicious breakfast ready to go for days! Proper storage ensures its freshness and delightful taste.

Refrigeration: Once baked and cooled, cover the baking dish tightly with plastic wrap or transfer individual servings into airtight containers. Store in the refrigerator for up to 4-5 days. This makes it ideal for preparing a batch on Sunday to enjoy throughout the busy work week.

Freezing: For longer storage, this baked oatmeal freezes beautifully. Allow the entire dish to cool completely. Then, portion it into individual servings. Wrap each portion tightly in plastic wrap, then place them in an airtight freezer-safe container or a freezer bag. It can be stored in the freezer for up to three months. When ready to enjoy, simply transfer a frozen portion to the refrigerator overnight to thaw, or reheat directly from frozen.

Reheating: To reheat refrigerated portions, simply warm them in the microwave for 1-2 minutes, or until heated through. If reheating a larger portion or from frozen, you can bake it again in the oven at 350°F (175°C) for 10-15 minutes (or longer if frozen) until thoroughly warmed. For frozen individual servings, you can microwave for 2-3 minutes, stirring halfway, until warm.

What to Serve with Your Coffee Cake Baked Oatmeal

While this baked oatmeal is undoubtedly delicious on its own, you can easily round it out into a more complete and satisfying meal. For a savory contrast, consider serving it alongside crispy turkey bacon or eggs prepared in your favorite way, such as our hearty crockpot breakfast casserole or an easy Instant Pot frittata. A vibrant side of fresh fruit or our refreshing winter fruit salad adds a lovely burst of freshness and extra vitamins.

Frequently Asked Questions (FAQ)

Can I use quick oats instead of old-fashioned rolled oats?
While you technically *can*, we highly recommend against using quick oats for this recipe. Quick oats are pre-cooked and finely cut, which means they absorb liquid much faster and can result in a mushy, less desirable texture in baked oatmeal. Old-fashioned rolled oats provide the best chewy, hearty texture.
How can I make this baked oatmeal sweeter or less sweet?
To make it sweeter, you can increase the amount of maple syrup in the oatmeal base or the sugar in the crumb topping. You could also add a drizzle of extra maple syrup or a dash of powdered sugar glaze after baking. For a less sweet version, reduce the maple syrup by half or omit it entirely from the oatmeal, and reduce the sugar in the crumb topping as well.
Is it possible to prepare this recipe ahead of time?
Absolutely! This Coffee Cake Baked Oatmeal is fantastic for meal prep. You can assemble the entire dish (oatmeal base and crumb topping) the night before, cover it tightly, and refrigerate it. In the morning, simply pop it into the preheated oven and bake as directed. This saves a lot of time on busy mornings!
What’s the best way to ensure the crumb topping is truly crumbly?
The key to a perfectly crumbly topping is to use very cold butter (or vegan butter). The cold butter, when pulsed with the oats and sugar, creates small pockets that resist melting quickly in the oven, leading to that distinct, crisp streusel texture. If your butter is too soft, it will combine too much with the other ingredients and result in a more cake-like topping.

We hope you love this Coffee Cake Baked Oatmeal as much as we do! It’s truly a wholesome and comforting dish that brings joy to any breakfast table. Enjoy the delicious flavors and the ease of a healthy, meal-prepped morning. Happy baking!
