Preheat your oven to 350°F (175°C).

In a medium skillet, melt the butter. Add sliced pears, granulated sugar, flour, cinnamon, and salt. Cook until bubbly and slightly thickened, about 5-7 minutes. Stir in vanilla extract and transfer to a baking dish.

In a large mixing bowl, combine all-purpose flour, light brown sugar, baking powder, and your choice of ground spices. Cut in cold butter until crumbly. Gradually mix in milk until a soft dough forms.

Spoon dollops of the topping over the pear filling, allowing some filling to peek through. Sprinkle sanding sugar if desired.

Bake for 30-35 minutes until topping is golden brown and filling is bubbling. Cool slightly before serving.

Serve warm or at room temperature, optionally with ice cream or whipped cream.
