- 1/4 cup flour: Essential for the streusel topping to achieve that tender crumb.
- 2 tablespoons brown sugar: Provides caramel-like sweetness to the topping.

How to Make Coffee Cake Baked Oatmeal Recipe
Step 1: Prepare Your Oven and Dish
Start by preheating your oven to 350°F (175°C). Grease a baking dish to prevent sticking—this small step guarantees an easy release and nice presentation after baking.
Step 2: Mix Dry Ingredients
In a large mixing bowl, combine the rolled oats, baking powder, cinnamon, and salt. These dry ingredients form the flavorful and textured foundation of your Coffee Cake Baked Oatmeal Recipe.
Step 3: Whisk Wet Ingredients
In a separate bowl, whisk together the milk, maple syrup, vanilla extract, egg, and melted butter. This mixture brings moisture and sweetness together, creating the custardy base that the oats will soak up.
Step 4: Combine Wet and Dry
Pour the wet ingredients into the bowl with the dry ingredients and stir gently until just combined. The oats will begin to absorb the liquid, yielding that soft but sturdy texture you’ll love.
Step 5: Make the Streusel Topping
For that classic coffee cake appeal, mix the flour, brown sugar, melted butter, and cinnamon in a small bowl until it forms a crumbly topping. This will create a delightful contrast in texture when baked on top of the oatmeal.
Step 6: Assemble and Bake
Pour the oat mixture into the prepared baking dish, evenly sprinkle the streusel topping over the surface, then bake for 30 to 35 minutes. You’ll know it’s ready when the top is golden brown and the oatmeal has set.
Step 7: Enjoy Warm
Once out of the oven, let it cool just slightly before serving. This Coffee Cake Baked Oatmeal Recipe is best enjoyed warm, letting that comforting aroma fill your kitchen as you dig in.
How to Serve Coffee Cake Baked Oatmeal Recipe

Garnishes
Add a personal touch by topping your oatmeal with fresh berries, a dollop of Greek yogurt, or a drizzle of maple syrup. These simple garnishes elevate the dish’s flavor and add a lovely contrast to the warm, spiced oats.
Side Dishes
Pair this coffee cake-inspired oatmeal with a cup of your favorite brewed coffee or a glass of freshly squeezed orange juice for a well-rounded breakfast. A side of crispy bacon or scrambled eggs also works beautifully to balance sweetness with savory.
Creative Ways to Present
Serve individual portions in cute ramekins or mason jars for a fun, grab-and-go twist. Layering with yogurt and fresh fruit can transform this into a parfait-style treat, perfect for impressing overnight guests or celebrating special mornings.
Make Ahead and Storage
Storing Leftovers
Place any leftovers in an airtight container and refrigerate. The Coffee Cake Baked Oatmeal Recipe keeps well for up to 4 days, making it an excellent option for meal prepping your weekday breakfasts.
Freezing
You can freeze portions individually wrapped or in freezer-safe containers for up to 2 months. Just be sure to thaw overnight in the fridge before reheating to preserve texture and flavor.
Reheating
Reheat in the microwave for 1 to 2 minutes or in a preheated oven at 325°F (160°C) until warmed through. Adding a splash of milk before reheating brings back that creamy softness and prevents it from drying out.
FAQs
Can I use steel-cut oats instead of rolled oats?
Steel-cut oats have a much firmer texture and longer cooking time, so they aren’t ideal for this baked oatmeal recipe. Rolled oats absorb liquid better and create the tender texture you want.
Is it possible to make this recipe dairy-free?
Absolutely! Substitute the milk with any plant-based milk like almond or oat milk, and use vegan butter or coconut oil in place of butter to keep this dish dairy-free without sacrificing flavor.
Can I make this recipe vegan?
To make it vegan, replace the egg with a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water) and use plant-based milk and vegan butter. The texture will be just as satisfying.
How do I adjust sweetness if I prefer less sugar?
You can reduce the maple syrup and brown sugar amounts by up to half without compromising the cozy flavor. Alternatively, try adding a bit of mashed banana for natural sweetness.
What’s the best baking dish size for this recipe?
A 9×9 inch square baking dish works perfectly, allowing for an even layer of oatmeal to bake through thoroughly while giving ample surface area for the streusel topping.
Final Thoughts
This Coffee Cake Baked Oatmeal Recipe is a wonderful way to start your day with something warm, cozy, and a little special. It’s a recipe that combines the nostalgic charm of coffee cake with the wholesome goodness of oats, offering comfort and energy in every bite.
