Preheat the oven to 375℉. Line a muffin tin with 12 liners and set aside. Chop the apples into small pieces and set aside.
2 cups apples
In a medium-sized bowl, add the dry ingredients in. Stir together and set aside.
2 cups all purpose flour, 2 tsps baking powder, 1 tsp baking soda, 3/4 tsps cinnamon, 1/2 teaspoon salt
In a large bowl, add oil, eggs, sour cream, vanilla, and white sugar. Whisk together until combined and smooth.
1 cup white sugar, 1/2 cup oil, 2 large eggs, 1 cup sour cream, 1 tbsp vanilla
Add in the dry ingredients and using a spatula, slowly fold until a soft muffin batter forms. Mix until JUST combined.
Add in the apples and mix in. Do not over-mix!
2 cups apples
Evenly divide the batter between the muffin liners.
Sprinkle extra white sugar on top. This will give you that nice muffin top ‘crunch’ that we all love on top of the muffins.
Bake the muffins at 375°F for 18-22 minutes. The muffins are ready when they bounce back at touch or a toothpick inserted comes out clean.
