Blackberry Crumb Pie Recipe with Easy Crumble Topping

I love the gorgeous purple of this Blackberry Crumb Pie — it is honestly one of the best pies I’ve ever pulled out of the oven, and that is saying something! 🫐 Whether you’re hunting for the perfect blackberry crumb pie for a summer cookout or just need a delicious dessert that will make everyone at the table lose their minds, this berry crumble pie recipe totally delivers. It’s fruity, buttery, and has that perfect amount of crunch on top. Be still my heart!

I’m not really into coloring my food red and blue for July 4th — not that it bothers me when anyone else does it! It’s just that once I get started on a dessert and it’s time to pull out the food coloring, I think, “why bother?” And back in the cupboard it goes. But I can totally get behind fresh blackberries for the 4th! Does anything say summer better than a fruit-filled pie loaded with juicy berries in July?? This is truly the ultimate summer dessert, you guys. 🙌

Why This Blackberry Crumb Pie Is the Perfect Fruit Pie

After a lot of experimenting, I am convinced this is the perfect fruit pie formula. The homemade blackberry pie filling is made with juicy blackberries, a little sugar, lemon juice, and just the right amount of cornstarch — no dry cornstarch clumps, no soupy mess. The amount of cornstarch matters so much for that thick, glossy blackberry filling! You can even make a quick cornstarch slurry by whisking it into a small bowl with a splash of juice first — that helps it dissolve perfectly into your berry mixture. Add a bit of ground ginger and a splash of vanilla extract and oh my goodness, it elevates the flavor of any dish instantly. ✨

How to Make the Flaky Pie Crust and Buttery Crumble Topping

Let’s talk crust! The easiest way to get a flaky pie crust is to start with cold butter pieces and work them into your flour mixture using a pastry blender in a large mixing bowl until you get small chunks of butter throughout. Add a little cold water — just a tablespoon at a time — until a shaggy dough forms. Turn it out onto a lightly floured surface, shape it into a ball of dough, and chill it. Then roll it out with a rolling pin on your work surface and press it into a 9-inch pie plate. You can also use a store-bought crust, a shortbread crust, or even a graham cracker crust for a different type of crust experience — all totally delicious! For a gluten-free crust option, just swap in your favorite GF blend. 💛

For the crumble topping, whisk your dry ingredients — purpose flour, white sugar, and brown sugar — together in a large bowl. Cut in real butter (room temperature works here!) with a pastry blender until you get that perfect buttery crumble texture. This crumb topping is what makes the whole thing magical, I literally can’t even.

Baking Tips for the Best Blackberry Crumble Recipe

Once you place pie into the oven, set it on a baking sheet to catch any drips — trust me on this one! Brush the edges of the unbaked pie crust with a beaten egg for that gorgeous golden brown finish. Cover with aluminum foil for the first 20 minutes so the top crust doesn’t over-brown while the pie bakes through. The juicy filling will be bubbling and the classic pie crust will be perfectly flaky. It’s giving perfect balance of tart and sweet! This recipe is also super close to my Blackberry Praline Crumble — another fave — and honestly if you love an apple blackberry crumble vibe, try mixing it up like my Razzleberry Pie! 🫐

Serving and Storing Your Pie

Serve warm with a big scoop of vanilla ice cream — that’s the perfect way, full stop! Leftover blackberry crumble pie keeps beautifully in an airtight container at room temperature for up to two days or in the fridge for up to four. You can grab fresh blackberries at your local market all summer long — they’re in their glory right now!

• 12 tablespoons butter

Instructions

Notes

Fresh or frozen blackberries both work well in this recipe — no need to thaw frozen berries before using. Adjust the sugar in the filling between ¼ and ½ cup depending on how sweet or tart your berries are. Store leftover pie covered at room temperature for up to 2 days, or refrigerate for up to 5 days.
