Heat your oven to 350°F (175°C). Put paper liners in a muffin pan or lightly grease them.
In a bowl, mix the flour, baking powder, baking soda, salt, cinnamon, nutmeg, and cloves.
In another bowl, beat the pumpkin puree, granulated sugar, brown sugar, oil, eggs, and vanilla extract.
Slowly add the dry mix to the wet mix. Don't mix too much, just until it's all together.
Put the diced apples in the batter and mix gently.
Use a cookie scoop or spoon to put the batter evenly in the muffin cups. Fill them about ⅔ full.
Bake for 18-20 minutes until a toothpick you stick in the muffins comes out clean.
Let the muffins cool in the pan for a bit. Then, put them on a wire rack to cool down more.
