Preheat the oven to 350ºF. Grease a muffin pan with coconut oil or line with muffin liners.
In a large bowl whisk together sugar, oil, vanilla, chia egg (or regular egg), "butter milk", orange zest and juice. Set aside.
In another bowl, stir together the dry ingredients until combined. Pour into the wet ingredients and mix until fully incorporated.
Fold in the raspberries. Transfer the batter to the prepared muffin pan, filling each hole to the top. Bake for 20-25 minutes or until a toothpick comes out clean.
Cool in the muffin pan for at least 5 minutes before removing. The muffins will keep for 5 days in an airtight container on the counter.
