Start by preheating your oven to 190°C (375°F). This is essential for achieving the perfect bake on your muffins.

Next, prepare a 12-cup muffin pan by placing paper liners in the cups and lightly greasing them with oil.

In a large bowl, combine pumpkin puree, white sugar, brown sugar, sunflower oil, yogurt, eggs, and vanilla paste. Make sure to mix until the mixture is smooth and well combined.

In a separate bowl, whisk together the dry ingredients including flour, baking powder, baking soda, cinnamon, ginger, nutmeg, cloves, and salt. This step ensures that the spices are evenly distributed throughout the muffins.

Carefully add the dry ingredients to the wet mixture, folding gently until just combined.

Be cautious not to overmix, as this will result in dense muffins. It's okay if there are a few lumps.

Spoon the batter into the prepared muffin cups, filling each cup about two-thirds full to allow room for rising during baking.

For the streusel topping, combine flour, white sugar, and brown sugar in a bowl.

Add the cold butter and use your fingers to rub it into the mixture until crumbly. Evenly sprinkle this streusel over the top of each muffin.

Place the muffin pan into the preheated oven and bake for 15 to 17 minutes, until a toothpick inserted into the center of a muffin comes out mostly clean.

Allow the muffins to cool in the pan for about 5 minutes, then transfer them to a wire rack to cool completely.

If you choose to add the glaze, mix together powdered sugar, milk, cinnamon, and a pinch of salt until smooth.

Drizzle this over the cooled muffins before serving for an extra touch of sweetness.

Your delicious pumpkin muffins are now ready to be enjoyed! Perfect for a cozy fall treat or any occasion.
