This small blueberry pie is a smaller take on a classic blueberry pie, full of fresh blueberries that bake until warm and bubbling.
Why You’ll Love This Small Blueberry Pie Recipe
Some nights I want blueberry pie, but a full 9-inch one is far more than I need. So I make this small version instead, enough for just me or to share with my husband.
At this size, a shortbread crust works better than rolled pastry. You stir the dough together and pat it across the bottom of the dish, no rolling needed. Bake the shortbread on its own first so it firms up before the berries go on. Left open, the blueberries cook down and concentrate as they bake.
I like it best warm, the berries soft and bubbling, their juices thickened on top. Spoon it into a bowl, and the base underneath eats like a cookie.
If you like small desserts you can make in one dish, try my mini cherry pie and mini Dutch apple pie, both put together the same easy way. And when blueberries are what you’re after, my blueberry cobbler for one and mini blueberry crisp are two of the simplest ways to use them.
Ingredient Notes
Here’s a closer look at the blueberry pie ingredients and what each one does. If you have any left over from this small blueberry pie recipe, check out our Leftover Ingredients Recipe Finder.
Butter: Soften it but don’t melt it. Cool, pliable butter, about 30 minutes out of the fridge, creams smoothly with the sugar and bakes into a tender, cookie-like crust.
Sugar: Sugar works in both layers. In the crust it adds sweetness and helps it turn golden, and in the filling it pulls juice from the berries as they bake and balances the lemon.
All-purpose flour: Flour does two different jobs. In the crust it gives the shortbread its structure, and in the filling it’s the thickener, soaking up the juice the berries release so the filling sets instead of running.
Cornstarch: The cornstarch goes in the crust, not the filling. A small amount softens the flour so the baked crust stays tender rather than firm and dense.
Salt: A pinch balances the sweetness so the crust doesn’t taste flat.
Blueberries: Fresh blueberries are best here. They hold their shape and give off just enough juice as they bake. Frozen berries work too; thaw and drain them first so the filling isn’t watery. Use extra berries in a mini blueberry cake or small batch blueberry scones.
Lemon zest and juice: Both brighten the filling and keep the sweetness from feeling heavy. Most of the lemon flavor lives in the zest, so grate it off before you juice the lemon.
Recipe Variations
There are a few easy ways to adapt this small blueberry pie to what you have on hand.
Use a different berry: Swap the blueberries for the same weight (12 ounces) of blackberries, raspberries, or a mix. The crust and method stay exactly the same.
Add cinnamon or almond: Stir ¼ teaspoon ground cinnamon or ⅛ teaspoon almond extract into the filling for a different flavor.
Double it to serve four: Double every ingredient and bake in a 6×8-inch dish, watching for the filling to bubble before you pull it.
Add a streusel topping: Stir together ¼ cup flour, 1 teaspoon granulated sugar, 1 teaspoon brown sugar, and ¼ teaspoon ground cinnamon. Mix in 3 tablespoons softened butter with a fork until crumbly, then spoon it over the berries before baking until the topping is golden and the filling bubbles.
How To Make A Mini Blueberry Pie
Here’s how to make this single crust blueberry pie, step by step. For exact amounts, see the recipe card below.
- Make the crust: Preheat the oven to 350°F (177°C). Cream the softened butter and sugar with a hand mixer until smooth, then mix in the flour, cornstarch, and salt until a dough forms.
- Press and bake the crust: Press the dough evenly across the bottom of a buttered 5×5-inch baking dish. Bake for 18 to 20 minutes, until lightly golden, then set it aside to cool.
- Mix the filling: Stir the blueberries, sugar, flour, lemon zest, and lemon juice together in a small bowl, then spoon the berries evenly over the cooled crust.
- Bake the pie: Set the dish on a baking sheet and bake for 45 to 50 minutes, until the filling bubbles.
- Cool before serving: Let the pie cool for at least a few hours so the filling sets, or serve it warm.
Expert Tips
Use the right dish size: A 5×5-inch baking dish gives the right crust-to-filling depth. If you don’t have one, use a dish with a similar capacity, like a 4×6-inch, so the crust stays thick enough and the filling doesn’t bake too shallow.
Soften the butter, don’t melt it: It should be cool but give when pressed, holding an indentation. Melted butter won’t cream with the sugar, and the crust bakes greasy instead of tender.
Taste the berries and adjust the sugar: Blueberries swing in sweetness through the season. Taste a few first, then add a little more sugar if they’re tart or a little less if they’re already sweet.
Watch for bubbling across the whole top: The filling is done when it bubbles across the surface, not only at the edges. That’s the sign the flour has thickened the juices. If the top browns a little before then, that’s fine.
Thaw and drain frozen berries: Fresh blueberries are best, but frozen work if you thaw and drain them first. Otherwise the liquid they release makes the filling runny.
Troubleshooting
If your open-faced blueberry pie isn’t turning out quite right, here’s how to fix common issues like a runny filling, a soggy bottom crust, or a pie that’s too loose after baking.
Why won’t my blueberry pie filling set?
A filling that won’t set usually needs more time to bake and cool. Bake until the juices bubble across the whole surface, which is what thickens the filling, then let the pie cool for at least a few hours so it firms up. Slicing into it warm is the most common reason it looks runny.
Why is the bottom crust soggy?
A soggy bottom happens when the berries go on before the crust has baked and cooled. Bake the shortbread until lightly golden and cool it first, so it sets before the wet filling is added. For extra insurance, sprinkle a teaspoon of flour and sugar over the cooled crust before the berries, it absorbs juice and keeps the base from going soggy.
Can I fix a blueberry pie that is runny?
Yes. Let it cool fully first, since the filling firms up as it sets. Chilling it in the refrigerator firms it further. And if it’s still loose, a pie this small is best spooned into a bowl, where a softer filling eats much like a cobbler.
Serving Suggestions
Serve this mini blueberry pie warm, on its own or with a simple topping:
- A spoonful of homemade whipped cream.
- A scoop of no-churn vanilla ice cream for à la mode.
Frequently Asked Questions
You’ll need one pint of blueberries, which is about 2 cups or 12 ounces. That’s one standard clamshell container, just enough for this pie.
Yes, you can make it up to a day ahead. Bake it, let it cool, then cover and keep it in the refrigerator until you’re ready to serve.
Leftover blueberry pie keeps for 3 to 4 days in the refrigerator, covered. Bring it to room temperature or warm it briefly before serving.
Yes, but thaw and drain them first. Frozen berries release extra liquid, and draining keeps the filling from turning watery.
Yes. Use a 5×5-inch dish or a similar 4×6-inch one, and double everything in a 6×8-inch dish to serve four.
Yes, though the shortbread crust is easier and bakes up cookie-like. If you’d rather have a flaky pastry base, my mini pie crust works well, fit it into the dish and pre-bake it before adding the berries.

Can you use cast iron mini pan to make this?
Hi Nancy, it really depends on the size of your mini pan. We bake the pie in a 5×5 inch baking dish that has a capacity of 22 fluid ounces (you can see the one we use on the recipe page and on our store page). If your mini pan is the same size, then it should work fine.
I made this yesterday and had it both warm last night and room temperature for lunch today. So good! The blueberries tasted wonderful and the cookie crust is an attraction in itself. Great recipe and easy to make.
Thank you Joanie for the delicious recipes, adapted by a good cook, instead of trendy ones that require buying strange ingredients never used again or quicky versions that start with processed foods. You have saved us from the agony of eating the same thing for days in a row and the guilt of throwing out good food.
Can this blueberry pie be done in the air fryer, by doing the crust first and then adding the berries and then more air fryer time cooking?
This recipe has not been tested in an air fryer but an air fryer is just a small convection oven so anything that can be made in a regular oven can be made in an air fryer. You’ll just need to reduce the cooking time as convection ovens cook faster due to how they circulate heat using a fan.
Loved! Easy and so tasty!! Gram said she has a new favorite!
Would it be good to mix artificial sugar instead of the traditional sugars?
I haven’t tested this recipe with artificial sugars.
This recipe is easy to follow, simple to make and delicious to eat!

Thank you, this looks and sounds luscious. Definitely trying.
I love blueberries, so this is a great recipe which I must try. I may also make it with a very thin layer of crumble topping if you think that would work? Thank you for all your great recipes for us singletons.
That would be delicious, Janette.
