Step 1

Preheat oven to 350°F. Line a 12-cup muffin pan with muffin liners.

Step 2

Add flour, sugar, cinnamon, baking soda, tartar, and salt into a large bowl. Whisk together until evenly combined.

Step 3

Add in oil, vanilla, vinegar, and water. Whisk until batter is smooth.

Step 4

Divide batter evenly between the 12 muffin molds. Bake for about 18-22 minutes or until a toothpick inserted comes out clean.

Step 5

While muffins are cooling, whisk together topping ingredients into a small bowl. Once the muffins are cooled, the surface should get a little moist and sticky. Once the surface is sticky, dip tops of muffins into the cinnamon sugar topping.
