Mini Blueberry Crumb Pies
  • Filling & Finishing
  • 2 cups fresh or thawed, drained frozen blueberries
  • 2/3 cup granulated sugar, divided
  • 3/4 teaspoon fine sea salt, divided
  • 3 tablespoons cornstarch
  • 1 pinch freshly grated nutmeg
  • 3/4 teaspoon vanilla extract
  • 1 tablespoon unsalted butter
  • 1/4 cup old-fashioned oats
  • 1/4 cup all-purpose flour
  • 1/4 cup light or dark brown sugar
  • 1/4 teaspoon ground cinnamon
  • 4 tablespoons cold unsalted butter, cut into ¼-inch cubes
  • Press-In Cookie Crust
  • 8 tablespoons unsalted butter, room temperature
  • 1/4 cup light or dark brown sugar
  • 1 large egg yolk, room temperature
  • 1 teaspoon vanilla extract
  • 1 3/4 cups all-purpose flour
  • 1/2 teaspoon fine sea salt
  1. Make the filling: In a medium pot, toss the blueberries, ⅓ cup granulated sugar, and ¼ salt to combine. Heat over medium heat, stirring frequently, until the berries start to break down and become juicy, 3 to 5 minutes.
  2. In a small bowl, whisk the remaining ⅓ cup granulated sugar with the cornstarch. Sprinkle this mixture over the blueberries and stir to combine. Add the nutmeg and continue to cook until thick bubbles break the surface and the mixture thickens, 1 to 2 minutes.
  3. Stir in the vanilla and 1 tablespoon butter and mix to combine. Remove the mixture from the heat and let cool completely to room temperature (you can do this quickly by pouring it into a thin layer in a casserole dish or baking sheet).
  4. Make the crumb topping: In a medium bowl, stir the oats, flour, brown sugar, ½ teaspoon salt, and cinnamon to combine. Add the butter and mix until the mixture forms moist clumps.
  5. Make the crust: In the bowl of an electric mixer fitted with the paddle attachment, cream the butter and brown sugar on medium speed until light and fluffy, 3 to 4 minutes. Add the egg yolk and vanilla and mix to combine. Scrape the bowl well.
  6. Add the flour and salt and mix to combine. Scrape the bowl well, then add 1 tablespoon water and mix until a smooth cookie dough forms.
  7. Divide the dough into 12 even pieces. Heat the oven to 350°F/175°C with the oven rack in the center. Lightly grease a 12-cavity standard muffin pan.
  8. Use your hands to press each piece of dough into one cavity of the muffin pan, aiming to keep it even on the base and sides.
  9. Divide the blueberry filling between the prepared crusts, filling each about ½ inch below the top edge of the crust. Divide the streusel evenly among the pies.
  10. Transfer the pan to the oven and bake until the crust and streusel are deeply golden, and the blueberry mixture is bubbling, 40 to 45 minutes.
  11. Use a small offset spatula to run around the outside edge of each pie to help loosen it from the edges. Let the pies cool for 15 to 20 minutes, then remove them from the pan while they are still warm (if you let them cool completely, they will be more likely to stick to the pan—but be careful, they will be softer/prone to crumbling while they are still warm).
  12. Let the pies cool completely before serving.

I always have three kinds of hot sauce in my purse. I have a soft spot for making people their favorite dessert, especially if it's wrapped in a pastry crust. My newest cookbook, Savory Baking, came out in Fall of 2022 - is full of recipes to translate a love of baking into recipes for breakfast, dinner, and everything in between!

I was looking for an easy recipe to use a large volume of frozen figs and thought that they would substitute well in this recipe. They were amazing. Added a couple more spices and some lemon zest in the filling, just bc figs instead of blueberries. However the base of this recipe is spectacular and easy to execute. Will be using it again whenever I wind up with a need to bake and some extra fruit!

These were really fun to make with my toddler. I made different components and she helped press in dough, spoon in cooled filling and add the crumble. I felt it was perfect amount of pie dough for the muffin tins . The filling is amazing. My only critique is I wish the pie shell was a little sweeter because it's a lot of crust to inside ratio and the crust is a little plain. Would be great as a full size pie I bet!

You guys might want to do 1 + 1/2 recipe for the crust dough to make sure you have enough of it, and good luck pressing it in a muffins pan...very sandy... It was not a success for me so i ended up doing a regular pie in a 8'' ring. But the pie is amazingly good.
