Freeze a 1/2 cup (1 stick) of unsalted butter for at least 2 hours or overnight.

Heat the oven to 350°F.

In a large saucepan, melt the butter along with the sugar and lemon juice.

Toss the apples with the flour then add to the melted butter. Add the cinnamon and nutmeg and a pinch of salt, stirring occasionally, cook for about 10 minutes until the apples just begin to soften.

Transfer the apple mixture into a 12-inch skillet.

In a separate mixing bowl, mix together the flour, sugar, baking powder and cinnamon.

Grate the frozen butter and add to the flour mixture along with the milk, lightly mix until well combined but don't overwork it.

Using a large spoon, divide the dough into golf ball-sized portions and arrange on top of the apples with a bit of space left in between to allow for the biscuits to rise and spread.

Sprinkle the biscuits with a spoonful more of sugar and bake the apple cobbler in the preheated 350°F oven for 30 - 45 minutes or until the biscuits have started to lightly brown.

Serve warm with ice cream if desired.
