Preheat oven to 450 degrees.

Whisk together flour, brown sugar, and salt in a medium sized bowl and set aside.

Using a cheese shredded, grate butter into the bowl of dry ingredients.

Pour in buttermilk and gently combine.

Sprinkle flour on your working area or board and remove biscuit dough from bowl. Use your hands to flatten the dough and shape out to your preferred thickness of ½-3/4 inch.

Cut biscuit dough into circles using round cutter or back of a can.

Place cut biscuits onto greased cast iron skillet and bake for about 10-12 minutes or until they have risen and browned.

Melt butter and lemon juice in medium sized pan over low heat.

Whisk in sugar and turn heat up to medium heat. Watch until butter and sugar mixture begins to turn a caramel brown color which can take up to 8 minutes (make sure you do not burn!!).

Add in thinly sliced apples, cream, rum and vanilla extract and cook until tender over medium heat for 10-12 minutes. Remove from heat and allow to cool for 10 minutes until just warm.

Simply cut biscuits in half.

On the bottom half of each biscuit, add whipped cream and apples.

Sprinkle with ground cinnamon (if desired) and serve.
