How to Make It
Make waffles: Whisk buttermilk, oil, and eggs in a large bowl. Stir cornmeal, flours, coconut sugar, baking powder, and salt in a separate bowl. Slowly whisk cornmeal mixture into buttermilk mixture. Fold in bacon and chives. Let stand for 15 minutes.
Preheat waffle iron; preheat oven to 200°F. Make compote: Melt 2 tablespoons of the butter in a large skillet over medium-high heat. Add apples, thyme, and salt. Cook, stirring, until soft, about 6 minutes. Add maple syrup and vinegar; cook, stirring constantly, until apples are coated, 2 minutes. Remove from heat; stir in remaining 1 tablespoon butter.
Mist waffle iron with cooking spray. Cook waffles in batches until browned and done. Mist with additional cooking spray as needed. Keep finished waffles warm in oven. Serve waffles with compote.
