Creating your Chocolate Pumpkin Muffins is simple when you follow these easy steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C) and line a muffin tin with paper liners.
2. Mix Wet Ingredients: In a large bowl, combine the pumpkin puree, vegetable oil, granulated sugar, brown sugar, eggs, and vanilla extract. Whisk until smooth.
3. Combine Dry Ingredients: In a separate bowl, mix together the all-purpose flour, cocoa powder, baking soda, baking powder, salt, and ground cinnamon.
4. Combine Mixtures: Gradually add the dry ingredients to the wet ingredients, stirring until just combined. Be careful not to overmix.
5. Fold in Chocolate Chips: Gently fold in the chocolate chips, ensuring they are evenly distributed throughout the batter.
6. Fill Muffin Tins: Spoon the batter into the prepared muffin tin, filling each cup about 2/3 full.
7. Bake: Place the muffin tin in the preheated oven and bake for 20-25 minutes, or until a toothpick inserted into the center comes out clean.
8. Cool: Remove the muffins from the oven and let them cool in the tin for about 10 minutes. Then transfer them to a wire rack to cool completely.
