Creating Pumpkin Cinnamon Roll Muffins is a straightforward process. Just follow these steps:

1. Preheat your oven to 350°F (175°C) and line a muffin tin with paper liners.
2. Mix Dry Ingredients: In a large bowl, whisk together the flour, baking powder, baking soda, salt, cinnamon, nutmeg, and ginger until combined.
3. Prepare Wet Ingredients: In another bowl, combine the pumpkin puree, granulated sugar, brown sugar, vegetable oil, eggs, and vanilla extract. Whisk until smooth.
4. Combine Mixtures: Gradually add the wet ingredients to the dry ingredients, stirring until just combined. Be careful not to overmix; a few lumps are okay.
5. Prepare Filling: In a small bowl, mix the brown sugar and cinnamon for the filling. Add the melted butter and stir until the mixture resembles wet sand.
6. Fill Muffin Liners: Spoon a small amount of muffin batter into each muffin liner, just enough to cover the bottom.
7. Add Filling: Sprinkle a layer of the cinnamon sugar mixture on top of the batter in each muffin cup.
8. Top with Batter: Pour more batter over the filling until the muffin cups are about two-thirds full.
9. Swirl: Using a toothpick or skewer, gently swirl the batter and filling together for marbling.
10. Bake: Place the muffin tin in the preheated oven and bake for 25–30 minutes, or until a toothpick inserted in the center comes out clean.
11. Cool: Allow the muffins to cool in the tin for about 10 minutes before transferring them to a wire rack to cool completely.
