Easy Blueberry Crisp Ingredients

For specific amounts, please refer to the printable recipe card at the bottom of the post.

• Frozen blueberries – While we use frozen blueberries, you can certainly use fresh blueberries if you prefer.
• Vanilla cook-and-serve pudding mix – this helps thicken the filling. You will add the dry mix – do NOT make the pudding.
• Cinnamon – No crisp is complete without a dash of cinnamon.
• Nutmeg – helps to add a warm flavor to the crisp.
• Milk – While you can use a lower-fat variety, we recommend using full-fat milk for the best results.
• Old-fashioned oats – These rolled oats are the ideal variety to use. Avoid using quick oats — they will not produce a crunchy topping like old-fashioned oats do.
• Sugar – Regular white sugar works well in this recipe.
• Greek yogurt – This ingredient gives the sweet crisp a little bit of tanginess.
• Almond extract – Using almond extract gives the crisp a slight nutty flavor.

1. Add frozen berries, pudding mix, spices, and milk to the prepared baking dish and stir to combine.

3. Bake until the crisp is bubbly, then broil briefly until the top is golden brown.
4. Serve warm or at room temperature.

Easy Blueberry Crisp Recipe Notes/Tips

• For the best results, it is recommended to use old-fashioned oats for a crunchy, golden brown, and chewy crumble. Quick-cooking oats can be used as an alternative, but they will be softer. Steel-cut oats should be avoided as they won’t cook properly and instant oats will become too mushy.
• Using full-fat dairy products will asure that the crisp has a creamy texture.
• Broiling before removing the crisp from the oven will make the top of the crisp crunchy.
• Do not thaw the frozen blueberries.

Old-Fashioned Blueberry Crisp Variations

• Pudding – Switch out the vanilla for a different flavor, such as banana, lemon or cheesecake. 
• Fruit – Add any kind of berry for the fruit filling — try raspberries, blackberries, or strawberries.
• Sweetness – In the blueberry filling, you can opt for maple syrup, honey, brown sugar, or  your favorite sugar substitute.
• Citrus – For added brightness, add a touch of lemon juice or shave some lemon zest into the blueberry mixture before baking.
• Nuts – Swap out ½ cup oats in your crisp for chopped almonds, pecans, or walnuts to add an earthy crunch.
• Butter – For a buttery oat topping, place small slices of cold butter on the topping or mix melted butter into the topping before pouring over top of the blueberries.
• Skinny Option – Make this blueberry crisp diet friendly by using the 1 ounce sugar free cook and serve pudding, non-fat milk, splenda (or sweetener of choice), and non-fat Greek yogurt.

Serving Suggestions

• Ice cream – Serve with a big scoop of vanilla ice cream — or your favorite flavor – on top.
• Whipped cream – Add a dollop of whipped cream to the crisp. 
• Fresh blueberries – Sprinkle fresh blueberries over top. 
• Heavy cream – Pour a bit of cream over a bowl of warm crisp.
