Easy Blueberry Crisp Recipe with Oatmeal Topping

Don’t let the summer go by without making this blueberry crisp recipe!

It starts with ripe, juicy blueberries that are tossed in vanilla and cinnamon. Then, we’re topping them with a buttery oat crust that is simply to die for.

Top it all off with a scoop of ice cream and you’ve got one of the best desserts of summer! 

This is a super easy dessert that you can whip up in no time. 

Ingredients for this Blueberry Crisp Recipe

Here are the simple ingredients you’ll need to make this easy dessert:

• Blueberries. Fresh is best, but you can certainly use frozen. More on that later. 
• Sugar. We’re using regular granulated sugar in the filling, then brown sugar and raw sugar for the crumble topping. 
• Oats. Be sure you’re using traditional, slow cooking oats and not the instant kind. 
• Flour. All purpose flour can be substituted for gluten free flour for a gluten free dessert. 
• Lemon juice
• Cornstarch. This serves as the thickener for the blueberry filling, resulting in a thicker texture similar to blueberry pie filling. 
• Butter

How to Make this Blueberry Crisp Recipe

Make the Blueberry Filling

Mix your fresh berries with cornstarch, lemon juice, sugar and vanilla. At first, the mixture will look white but that color will go away as the cornstarch dissolves.

Set the filling mixture aside while you make the crisp topping. 

Make the Crisp Topping

Place the flour, oats, sugars, cinnamon and salt in a mixing bowl. Whisk everything together really well.

Then, melt the butter in the microwave and pour it into the flour mixture. Work the melted butter into the dry ingredients using a pastry blender or just a regular fork. 

Assemble the Blueberry Crisp

​Pour the blueberry filling mixture into a square baking dish, and sprinkle the crisp topping evenly over top.

Now, bake it until it’s golden brown and bubbly! 

Serving this Blueberry Crisp

Give this dessert 30 minutes to cool before serving it. For best results, serve at room temperature or slightly warm.

And whatever you do, don’t forget a big scoop of vanilla ice cream on top! 

 

Can you use frozen Blueberries in this recipe?

Yes, you can use frozen blueberries in this blueberry crisp recipe.

Be sure to allow them to defrost at room temperature for at least 30 minutes before using them.

What is the difference between a crisp and a cobbler? 

Both a crisp and a cobbler are baked desserts with a fresh fruit filling. The topping on a crisp is more crumbly and typically has oats included, while the topping on a cobbler is more like a biscuit dough and usually calls for eggs to make the batter more cakey.

A crisp topping is sprinkled evenly over the fruit filling, while a cobbler topping is dropped in spoonfuls over the fruit. 

What is the difference between a crisp and a crumble?

Although a crisp and a crumble are very similar desserts, there are a couple of distinct differences.

First, a crisp topping usually includes oats while a crumble topping does not. Second, a crumble topping more closely resembles streusel, while a crisp topping is more crusty. 

How to Store this Blueberry Crisp

This blueberry crisp can be covered with plastic wrap and left at room temperature for 1-2 days.

For longer storage, transfer it to the refrigerator. It will last, refrigerated, for 5-7 days. 

Can you freeze this blueberry crisp?

Yes you can! Transfer your blueberry crisp to an airtight container and freeze for up to 3 months. You can also freeze it before baking. 

Either way, allow it to thaw at room temperature before reheating or baking for the first time. 

Can you use other fruits? 

You can definitely use other fruits in this blueberry crisp recipe! Here are some ideas: 

1. Apple crisp. Make this classic dessert during the fall season! Add extra cinnamon to the fruit filling and try a little bit of nutmeg in the topping ingredients for added warmth.

2. Mixed berry crisp. Try adding raspberries, strawberries or blackberries for a medley that’s perfect for berry lovers! 

3. Peach crisp. Another great summer fruit, peaches are an easy swap for blueberries, or do a 50/50 combo of peaches and blueberries.
