Healthy Cinnamon Sugar Apple Muffins

To prep ingredients: Microwave or heat the coconut oil until it's liquified. Repeat the same process for the milk to bring it to room temperature. (If you don't do this, the coconut oil will clump together when it mixes with the cold milk.) Add the vinegar to the milk and let it sit for a few minutes to turn into "buttermilk" - or just use real buttermilk instead!For the muffins: Preheat the oven to 350 degrees. In a large bowl, whisk the coconut oil, buttermilk, brown sugar, egg, and vanilla until smooth. Add the flours, baking soda, baking powder, salt, and allspice. Stir until just combined. Fold in the apples. Scoop the mixture into a greased or lined muffin tin - mini, regular, or jumbo sizes will all work.For the topping: Melt the butter for the topping. Add the sugar and cinnamon; spoon over the tops of the muffins. You only need a little bit to get the crunchy top effect, but if you love those crunchy cinnamon sugar tops, I'd suggest making twice or three times as much topping as what's listed here.Bake the muffins for 15 minutes, more or less by a few minutes depending on size. The muffins should be golden brown with big round tops that spring back when you press them.
