Preheat your oven to 180°C.
Line a baking tray with muffin liners. If using a muffin tray, lightly coat it with oil to prevent sticking.
Begin by creating a homemade buttermilk substitute. In a jug, combine vinegar and oat milk, give it a swirl, and set it aside for 5 minutes.
Sift all the dry ingredients into a large bowl, then add the wet ingredients and mix until the batter is smooth and free of lumps. Gently fold in the chocolate chips to incorporate.
Spoon the muffin batter into your prepared muffin tins and bake for 20-25 minutes, or until a toothpick inserted into the center comes out clean. Once baked, remove from the oven and sprinkle with a few additional chocolate chips for a delectable finishing touch.
Enjoy these scrumptious muffins and savor the delightful flavors!
