This no bake lemon blueberry pie brings cool, creamy goodness without any cooking. It's the perfect summer treat when you're craving something chilled and tasty but don't want to heat up your house. With its eye-catching purple filling, this easy dessert turns into a fantastic frozen delight without much work.
I whipped up this pie during last summer's hot spell when I couldn't bear turning on my oven. Everyone in my family was amazed that something this quick to make could taste so fantastic. Now we can't get through summer without it.
Ingredients
- Lemon juice: go for freshly squeezed for that zingy kick that cuts through the sweetness
- Fresh blueberries: pick firm, round ones for the richest color and best taste
- Sweetened condensed milk: this gives you that smooth, creamy texture without any cooking
- Premade graham cracker crust: a real time-saver, though you can make your own if you want
Step-by-Step Instructions
- Blend the Filling:
- Throw the lemon juice, blueberries and condensed milk into your blender. Mix until it's smooth with tiny blueberry bits showing through. This gives you that stunning purple color and makes sure every mouthful has the right flavor balance.
- Fill the Crust:
- Dump your lovely purple mixture into the graham cracker crust, spreading it out evenly. Grab a spatula to flatten the top. This step matters for looks and helps ensure the pie has the same thickness everywhere.
- Freeze Until Set:
- Stick the whole pie in your freezer for about an hour until the filling gets firm. Freezing changes the runny mixture into that awesome texture like ice cream. Keep it frozen until you're ready to serve for the best results.

The cool thing about this pie is how the tangy lemon juice reacts with the condensed milk, letting us skip any cooking. My grandma taught me this trick with her famous lemon ice box pie. Adding blueberries kicks up both the flavor and the looks.
Texture Options
You can get different results depending on how you chill this pie. Freezing it gives you something like ice cream that's super refreshing when it's hot outside. If you want something softer more like pudding, just put it in the fridge instead. It'll take longer to set up, around 3 to 4 hours, but you'll get a totally different treat. Both ways taste amazing, just with different feels in your mouth.
Seasonal Variations
Blueberries make a gorgeous purple dessert, but you can switch things up year-round with whatever fruit is in season. Try using strawberries in spring for a pretty pink version, or go with blackberries in late summer for a deeper purple color. Mixed berries work great too and add more complex flavors while keeping things simple. Just make sure your chosen fruit goes well with the bright lemon and adjust the sweetness if you're using tart fruits.
Make It Fancy
You can dress up this easy pie for special occasions without much extra work. After the filling sets, place fresh blueberries around the edge or make a pretty design on top. Sprinkle some lemon zest over everything for better looks and extra flavor. To really wow people, put some whipped cream dollops around the edge right before serving and add mint leaves for garnish. These little touches make your dessert look store-bought fancy, even though it took minutes to make.

Recipe FAQs
- → Can frozen blueberries work instead of fresh?
Yep, they’ll work fine. Just let them thaw and remove any extra liquid to keep the mixture from getting too watery.
- → What can I do to make sure the crust stays firm?
Since this dessert is served cold, the crust stays solid. To avoid the crust softening, eat it as soon as it’s out of the fridge or freezer.
- → Can I swap out lemon juice for another juice?
Lemon juice is key for setting the filling. Swapping it could mess with the texture and taste, so it’s best not to replace it.
- → How long does it last in the freezer?
This dessert keeps well in the freezer for up to a month. Wrap it tightly with plastic or foil to avoid freezer burn.
- → Is there a way to make this dairy-free?
Yes! Use a plant-based condensed milk and check that the crust is vegan-friendly. The taste and feel might change a bit, though.
- → Any tips for decorating?
Add fresh blueberries, thin lemon slices, or some whipped topping. It’s best to decorate just before serving so everything looks fresh.
