Triple Berry Crumble Pie – A bright and tangy berry filling topped with a gorgeous crumble topping. This pie screams summer, but the filling is made with frozen berries, so you can make it all year round!
Developing pie recipes is one of my favorite things on earth.
It’s always a delicious experiment, and it requires making several test pies to perfect the recipe.
For months (and months), I’ve had a picture in my head of the perfect summer pie. I wanted plenty of summer berries and a gorgeous crumble topping on top. Then, I started second guessing myself and wondered if I’d be better off doing a top crust instead of a crumble topping.
I took a little poll of my friends and family on Facebook asking “double crust or single crust with crumble topping?” Guess what the results were?
Crumble topping overwhelmingly won out, though plenty of people love a top crust and some people even said to do both (a crumble topping and then a lattice on top of that!).
This pie is just heaven. The filling is flexible–you can use all berries (raspberries, blackberries, and blueberries), or you can use a mixture of berries and cherries. Both are delicious. I know because I’ve eaten roughly my body weight in pie lately. #pieforbreakast #onlysortofkidding
A crumble topping can sometimes make a pie a bit too sweet for me, so I mitigated the issue by adding just enough sugar to sweeten the berries and let the crumble do most of the sweetening. I almost always use natural sweeteners these days, and while I do have a great naturally sweetened crumble topping, I decided to really go for it on this pie. If you’re not going to let your hair down on holidays or special occasions, when are you going to let it down?
Another big plus for this pie is that I used frozen fruit. While fresh berries are in season (and you can absolutely use them in this recipe), I wanted to be sure that the recipe would work just as well for Thanksgiving or Christmas when berry season is long gone.
So, there you have it. The berry crumble pie that is equally at home at a 4th of July party with a big dollop of vanilla ice cream, or at Thanksgiving dinner. Beautiful, simple, and everything I hoped for.
FAQ + Tips For The Best Triple Berry Crumble Pie:
Can You Use Frozen Berries For Triple Berry Pie? Yes! I recommend using 1 Tbsp. extra cornstarch when you use frozen berries, since the frost from the berries can add extra moisture.
Tips To Get The Sweetness Just Right. Depending on the sweetness of your berries, you may prefer to increase the sugar. I prefer my filling to have a tiny bit of tartness since the crumble topping is sweet enough, and in all my tests (with tart cherries and blackberries), 1/2 cup was plenty for me.
What’s Your Favorite Pie Crust Recipe? Pie crust is a serious business at our house. This is our favorite recipe using white flour (for non-gluten-free folks), and this is our favorite gluten free pie crust recipe.
For the gluten free… Bob’s Red Mill 1-to-1 gluten free baking flour is our go-to for recipes like this one. It’s a true 1-to-1 substitute for white all purpose flour and both my crust and the crumble topping turned out beautifully.
Use A Big Pie Dish If You Can! This is a hefty pie. It fits in a standard 9-inch pie plate, but if you’ve got a deep dish pie pan, you’ll probably feel a *little* more comfortable putting it into the oven.
