Our blackberry pie with crumble topping is arguably one of the most popular ones that we’ve ever shared. It’s not just incredibly delicious, but it’s also easy because you make the filling on the stovetop using frozen blackberries.

The filling gets nice and thick, so there’s no worry about it setting up properly while it bakes. It has the right amount of sweetness with a hint of warmth from the ground ginger. And, that buttery crumble topping! It adds the perfect amount of crunch.

Have a slice with a scoop of vanilla ice cream or cold straight from the fridge! Either way, this one is a family favorite.

Kim’s Tips

Tips
  • Place the pie pan on a foil lined baking sheet. This makes it easier to get it in out and of the oven and catches any potential spills. 
  • Use a foil tent. Sometimes the crust or the crumb topping starts to brown too quickly. Loosely drape a foil tent over the top if this happens.
  • Add other fruits. If you don’t have enough blackberries, use blueberries, strawberries, cherries, or apples to make up the difference.
  • Use a different type of crust. A shortbread crust, graham cracker crust, or gluten-free crust all taste great with our blackberry crumble pie.
  • Store bought crust. If you don’t want to make a homemade pie crust, buy one at the store. It works just as well.

How to Store Leftovers

Refrigerator: Store any leftover blackberry crumble pie in the fridge for 4-5 days.

Freezer: Chill the pie in the fridge, then wrap it tightly in plastic wrap followed a couple of layers of aluminum foil. It will stay good in the freezer for about 2 months.

Thawing and Reheating: Thaw the pie in the fridge or at room temperature. Reheat in the microwave for a few seconds until warmed through.

FAQs (Frequently Asked Questions)

This one is my favorite tips! Brush a beaten egg onto the bottom, sides, and edges of the unbaked pie crust to create a moisture barrier. This technique ensures that as the pie bakes, the crust remains buttery and flaky, preventing the juicy filling from making it soggy.

To make the filling thicker, add more cornstarch slurry. The amount of cornstarch needed can vary depending on how juicy the fruit is. Don’t add the dry cornstarch directly to the filling. It needs to be mixed with a little cold water first.

Notes

*The calories listed are an approximation based on the ingredients in the recipe card and a serving size of 1 slice of pie. Actual calories will vary.
 
*As the blackerries thaw, save about ½ cup of the juice/liquid to use in the filling. Sometimes this isn’t needed if the berries release a lot of juice as the filling cooks. If that’s the case, simply discard it once the filling gets done.

    1. Hi Jenn!

      I’m so sorry for the delay in responding to your question. We had an issue with the software that handles our comments.

      We let our frozen crusts thaw in the fridge overnight or thaw at room temperature for 15-20 minutes before baking and haven’t needed to adjust the baking time. Hope that helps! 🙂
