- 1/2 teaspoon cinnamon: Adds a cozy warmth and aromatic spice that compliments the blueberries beautifully.
- 1/4 teaspoon salt: Balances the sweetness and enhances all the flavors in the dish.
- 1 teaspoon baking powder: Gives a slight rise, making the oats tender without being cakey.
- 1 3/4 cups milk of choice: Keeps the oatmeal moist and creamy; use your favorite dairy or plant-based milk.
- 1/4 cup maple syrup: A natural sweetener that imparts rich caramel notes and ties the blueberries and oats together.
- 1 large egg: Binds the ingredients for a perfect consistency and adds a bit of richness.
- 1 teaspoon vanilla extract: Elevates the flavor with a subtle, sweet aroma.
- 2 tablespoons melted butter or oil: Adds moisture and richness to the oatmeal base.
- 2 cups blueberries: The star fruit – juicy, tangy, and bursting with antioxidants.
- 1/2 cup rolled oats (for topping): Creates that signature crisp on top.

How to Make Blueberry Baked Oatmeal Crisp Recipe
Step 1: Prepare Your Baking Dish and Oven
Start by greasing an 8×8 inch baking dish to ensure your creation doesn’t stick. Preheat the oven to 375°F (190°C) so it’s ready to bake the oatmeal crisp to a golden perfection once you assemble everything.
Step 2: Mix the Dry Ingredients
In a spacious bowl, combine the rolled oats, cinnamon, salt, and baking powder. This blend of dry ingredients forms the base and spicy undertone of the dish, creating a robust flavor foundation before the wet ingredients join the party.
Step 3: Whisk the Wet Ingredients
In a separate bowl, whisk together the milk, maple syrup, egg, vanilla extract, and melted butter. This mixture brings creaminess, sweetness, and structure—each element playing its part to turn the oats into a custardy, luscious base.
Step 4: Combine and Fold in Blueberries
Now, pour the wet ingredients into the dry ingredients and stir gently to combine. Fold in the fresh blueberries carefully to keep them from bursting and staining the mixture too much; you want juicy pockets of fruit throughout.
Step 5: Pour Mixture and Make Topping
Pour the prepared oatmeal mixture into the greased baking dish, smoothing it out evenly. Then prepare the topping by mixing together the half cup of rolled oats, flour, brown sugar, and butter until crumbly.
Step 6: Sprinkle Topping and Bake
Sprinkle the crisp topping evenly over the blueberry oatmeal base. Bake the dish in the preheated oven for 40 to 45 minutes, or until the top is golden brown and crisp, and the inside has set into a tender, comforting texture.
Step 7: Cool Slightly Before Serving
Let your Blueberry Baked Oatmeal Crisp cool for a few minutes before serving so the flavors settle and it firms up slightly, making it easier to portion and savor every bite.

Garnishes

Make Ahead and Storage
Storing Leftovers
Leftover Blueberry Baked Oatmeal Crisp keeps well in the refrigerator for up to 4 days, covered tightly with plastic wrap or in an airtight container. The flavors deepen, making reheated portions even more delightful.
Freezing
This recipe freezes beautifully. Wrap individual portions or the whole dish tightly in plastic wrap and foil, then freeze for up to 3 months. Thaw overnight in the fridge before reheating for a quick and convenient breakfast.
Reheating
Reheat your crisp in the oven at 350°F (175°C) for about 10-15 minutes to revive that irresistible crispness, or microwave single servings for a minute or two if you’re short on time. Keep a close eye so it doesn’t dry out.
FAQs
Can I use frozen blueberries instead of fresh?
Absolutely! Frozen blueberries work perfectly in this Blueberry Baked Oatmeal Crisp Recipe. Just don’t thaw them first to avoid extra moisture—fold them in frozen and bake as directed.
Is it possible to make this recipe gluten-free?
Yes! Simply use certified gluten-free rolled oats and a gluten-free flour blend for the topping to keep everything safe for those with gluten sensitivities.
Can I substitute the maple syrup with another sweetener?

What type of milk works best for this recipe?
Any milk you enjoy will work, from dairy to almond, oat, soy, or coconut milk. Each will subtly influence the flavor, so pick one that complements your taste.
How do I make the topping extra crunchy?
For a crunchier topping, add chopped nuts like pecans or walnuts to the crumb mixture before baking. Toasting the oats lightly beforehand can also enhance crispness.

- 1/4 cup maple syrup
- 1 large egg

- 2 cups blueberries
Topping
- 1/2 cup rolled oats
- 2 tablespoons flour
- 2 tablespoons brown sugar
- 2 tablespoons butter
Instructions
- Prepare the baking dish and oven: Grease an 8×8 inch baking dish thoroughly to prevent sticking. Preheat your oven to 375°F (190°C) to ensure it’s at the right temperature for baking the oatmeal crisp evenly.
- Mix dry ingredients for base: In a mixing bowl, combine 2 cups rolled oats, 1/2 teaspoon cinnamon, 1/4 teaspoon salt, and 1 teaspoon baking powder. Stir well to distribute the spices and leavening evenly.
- Whisk wet ingredients: In a separate bowl, whisk together 1 3/4 cups milk of your choice, 1/4 cup maple syrup, 1 large egg, 1 teaspoon vanilla extract, and 2 tablespoons melted butter or oil until fully blended and smooth.
- Combine wet and dry mixtures: Pour the wet ingredients into the bowl with dry ingredients and mix until just combined. Then gently fold in 2 cups fresh blueberries to distribute without breaking them.
- Pour mixture into dish: Transfer the oatmeal mixture evenly into the prepared baking dish, smoothing the top slightly with a spatula for even baking.
- Prepare the topping: In a small bowl, mix together 1/2 cup rolled oats, 2 tablespoons flour, 2 tablespoons brown sugar, and 2 tablespoons butter. Use your fingers or a fork to work the butter into the dry ingredients until the mixture forms a crumbly texture.
- Sprinkle topping: Evenly sprinkle the oat crumble topping over the oatmeal base, covering it uniformly to achieve a crisp crust when baked.
- Bake the oatmeal crisp: Place the baking dish in the preheated oven and bake for 40 to 45 minutes. Bake until the top turns golden brown and crisp, and the oatmeal is set and cooked through.
- Cool before serving: Remove the baked oatmeal crisp from the oven and let it cool slightly for about 5-10 minutes. This helps the dish to set further and makes serving easier.
