Ingredients You’ll Need
These ingredients are wonderfully simple yet carefully chosen to create a delightful harmony of flavors and textures in your baked oatmeal crisp. Each component plays its part, from the creamy oats to the sweet-tart blueberries and that irresistible buttery topping.
- Old-fashioned rolled oats: The base of the dish providing chewiness and fiber-rich goodness.
- Unsweetened almond milk: Adds moisture and a subtle nutty flavor without overpowering the dish.
- Pure maple syrup: Natural sweetness that perfectly balances the tart blueberries.
- Ground cinnamon: Warms the flavor profile with a hint of spice.
- Large egg (or flax egg): Binds everything together for a custardy texture.
- Baking powder: Helps the oatmeal rise slightly for a light, tender bite.
- Fresh or frozen blueberries: Bursting with juicy flavor and gorgeous color.
- All-purpose flour (or gluten-free alternatives): Key for the streusel crisp, creating that crumbly, buttery topping.
- Brown sugar (or coconut sugar): Adds rich sweetness and complements the oats beautifully.
- Salt: Enhances all the flavors and balances the sweetness.
- Melted coconut oil (or butter): Binds the streusel topping and lends a lovely richness.
How to Make Overnight Blueberry Baked Oatmeal Crisp Recipe
Step 1: Prepare the Oat Mixture
Start your delicious journey by combining the oats, almond milk, maple syrup, and cinnamon in a medium bowl. Stir these ingredients well to ensure every oat is coated with that sweet and spicy goodness. Cover the bowl and refrigerate it overnight — this soaking step is essential because it softens the oats and infuses them with flavor, setting the foundation for your crisp breakfast.
Step 2: Preheat Your Oven and Prep the Baking Dish
The next morning, preheat your oven to 375°F (190°C). While it warms, grease an 8×8-inch baking dish to prevent sticking and make cleanup easier. Getting this ready early helps you keep the momentum going and makes the process delightfully smooth.
Step 3: Mix in the Eggs and Baking Powder, Then Fold in Blueberries
Remove your oat mixture from the fridge and add the beaten egg along with the baking powder. Stir until everything is perfectly combined—the egg will help the oats set nicely when baked. Gently fold in the blueberries last, so they remain whole and juicy rather than bursting prematurely.
Step 4: Whip Up the Streusel Topping
In a separate bowl, mix together the oats, flour, brown sugar, and salt. This is where the magic starts for that signature crisp. Slowly stir in the melted coconut oil or butter until the mixture becomes crumbly. This topping adds the ideal contrast to the creamy baked oatmeal underneath.
Step 5: Assemble and Bake to Perfection
Pour the oat and blueberry mixture into your prepared dish, smoothing it evenly. Sprinkle the streusel topping generously over the surface. Slide the dish into the oven and bake for 30 to 40 minutes until the top is golden brown and the oatmeal is set. If the topping darkens too quickly, lightly cover the dish with foil to prevent burning.
Step 6: Cool and Enjoy
Allow your Overnight Blueberry Baked Oatmeal Crisp Recipe to cool for 10 to 15 minutes after baking — this rest time helps it firm up slightly and makes serving a breeze. Best enjoyed warm, it’s comfort food at its finest.

FAQs
Can I use frozen blueberries in the Overnight Blueberry Baked Oatmeal Crisp Recipe?
Absolutely! Frozen blueberries work wonderfully if you thaw them slightly and blot off excess moisture before folding them into the batter to avoid excess liquid.
Is it possible to make this recipe vegan?
Yes! Swap the egg for a flax or chia egg, and use melted coconut oil instead of butter to keep it entirely plant-based without sacrificing flavor.

This recipe strikes a nice balance of natural fruity sweetness and maple syrup. However, you can reduce the sweetener slightly or use a sugar substitute to suit your taste.
What’s the best way to serve leftover baked oatmeal crisp?
Leftovers taste fantastic warmed up with a splash of milk or topped with fresh berries and a dusting of powdered sugar for a little extra flair.
