#### **Step 1: Make the Dough**

In a mixing bowl, whisk together **flour, sugar, baking powder, and salt**. Cut in **cold butter** using a pastry cutter or fork until the mixture resembles coarse crumbs. Stir in **milk** until a dough forms.

#### **Step 2: Prepare the Filling**

In a small bowl, mix **diced apples, brown sugar, cinnamon, and nutmeg**. Set aside.
