Easy bottom layer pie crust

For the crust:
1 3/4 cups all-purpose flour 228 grams
1/2 tsp kosher salt
1 tsp granulated sugar
1/2 tsp baking powder
1/2 cup unsalted butter, cubed 113 grams
3 tbsp whole milk

To make the crust, whisk the dry ingredients in a large mixing bowl. Heat the butter and milk together in either a 2-cup glass measuring cup or a glass bowl in a microwave on high, in 3 thirty second bursts, stirring in between each, until the butter is melted and the milks is steaming hot – the mixture doesn't need to boil. Pour the hot liquid over the flour mixture and stir with a fork until the mixture holds together when squeezed and there are no loose bits of flour left in the bowl. Evenly press the dough onto the bottom and up the sides of the pie plate using your fingers. Decorate the edges with a fork, if you so desire, and brush them with the egg wash.
