4 Set your oven to [wprm-temperature value="400" unit="F"] and center your oven rack.
3 Line a 12 cavity muffin tin with baking cups or parchment paper. If you prefer, spray with nonstick spray if you do not want to use liners.
0 In a large bowl, whisk together all the dry ingredients: all-purpose flour, granular sugar, baking powder, and salt. * If you are adding other spices, cinnamon or garlic, they will be added here.
1 In a separate small bowl, lightly beat the wet ingredients: milk, egg, and avocado oil.* If you are adding extracts, vanilla, they will be added here.
2 Add the wet ingredients to the dry ingredients. Fold 18 times with a spatula.* If you are adding add-ons, fruit, chocolate chips, bacon, cheese, they will be added here. Fold batter 10 times, add the add-ons, and fold remaining 8 times.
5 Divide batter equally into your muffin tins, filling them 2/3 of the way full. I use an ice cream scoop to do this.
6 Bake for 12 – 17 minutes, this will vary based on the add-ons. The muffin should spring back to the touch when it's done and be light brown on top and sides.
7 Let cool for 10 minutes before removing from the muffin tin. Place on a wire rack to cool to room temperature.
