Combine your flour, baking soda and powder, salt, cinnamon, and sugar in a large bowl.
With a fork, or your hands, work the cubed butter into the flour mixture until the texture is crumbly.
Then add your buttermilk, and mix until the dough forms a ball. If the mixture is too wet, add a bit more flour until manageable.
Grease your pan/skillet and preheat your oven to 400℉
Pinch off handfuls of dough until you have 8 large biscuits, and place them in your pan.
Top your biscuits with the cinnamon sugar mixture, and bake for 15-20 minutes, until the biscuits are golden brown on top.
Let cool, then slice in half and add your strawberries and whipped cream!
