¾cupdried blueberries or 1 cup fresh, tossed in a teaspoon of cornstarch
Instructions
Make the Milk Crumb first.
Preheat oven to 225 and have ready a parchment lined baking sheet.
Whisk together 2 ½ tablespoons of dry milk powder plus flour, cornstarch, sugar and salt, then stir in melted butter until coated.Spread on parchment sheet and bake for 10 minutes or until dry. Remove from oven and let cool. Transfer to a bowl and stir in remaining milk powder and melted white chocolate. Let cool and refrigerate until ready to use.
Preheat oven to 375 degrees F.
Whisk together flour, baking powder, baking soda and salt.
In a stand mixer using the paddle attachment, beat together the softened butter, sugars, and glucose for 3 to 4 minutes on medium speed. Scrape down the side of the bowl. Add eggs and beat for 7 to 8 minutes (I only beat for 3 to 4). Add flour mixture and mix until well combined. Don't overbeat. Add the milk crumb mixture and stir until mixed, then add blueberries.
Use an ice cream scoop to scoop dough into balls, spacing about 2 inches apart on parchment lined baking sheets. Bake for about 15 minutes (it may take longer, especially if the dough is cold or frozen), rotating pans halfway through, until cookies are golden brown and tops begin to crack.
