Creating Pumpkin Spice Streusel Muffins is simple if you follow these easy steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Line a muffin tin with paper liners or grease it lightly.
2. Mix Dry Ingredients: In a large bowl, whisk together 1 ½ cups of all-purpose flour, granulated sugar, brown sugar, baking powder, baking soda, salt, cinnamon, nutmeg, and cloves until well combined.
3. Combine Wet Ingredients: In another bowl, mix together the pumpkin puree, vegetable oil, eggs, and vanilla extract until smooth.
4. Combine Mixtures: Gradually add the wet ingredients to the dry ingredients, stirring just until combined. Be careful not to overmix; a few lumps are fine.
5. Prepare Streusel: In a small bowl, combine ½ cup of flour, brown sugar, and cinnamon for the streusel. Add the cold butter and mix with a fork or pastry cutter until crumbly.
6. Fill Muffin Cups: Divide the muffin batter evenly among the prepared muffin cups, filling each about ¾ full. Sprinkle the streusel topping generously over each muffin.
7. Bake: Place the muffin tin in the preheated oven and bake for 18-20 minutes, or until a toothpick inserted in the center comes out clean.
8. Cool: Remove the muffins from the oven and let them cool in the pan for about 10 minutes. Then, transfer them to a wire rack to cool completely.

These steps will guide you through the process of making delicious Pumpkin Spice Streusel Muffins effortlessly. The result will be a batch of warm, fragrant muffins that everyone will love.
