Step 1

Combine the sugar, flour, and nutmeg in a small bowl then work in the butter, using a fork or pastry cutter to combine. Work until the mixture has a crumb-like texture. Set aside.

Step 2

Heat the oven to 375ºF. Spray a 9-inch square glass baking dish with nonstick cooking spray and set aside.

Step 3

Whisk the flour, baking powder, salt and ginger together in a medium bowl and set aside.

Step 4

In a stand mixer fitted with a paddle attachment, beat together the butter and sugar on medium speed until light and fluffy, approximately 1 minute. Reduce the speed a bit and thoroughly incorporate the egg. Reduce speed to low and add one-third of the flour mixture. Once incorporated, add one-third of the milk then repeat alternating until all ingredients are combined.

Step 5

Gently stir in the blueberries and pour the mixture into the prepared baking dish and sprinkle on the topping mixture.

Step 6

Bake on the middle rack of the oven until golden, about 45 minutes. Cool for 30 minutes before serving.
