- Preheat your oven to 375°F (190°C) and line a muffin tin with paper liners or lightly grease it. 
- In a large mixing bowl, whisk together the flour, sugar, baking powder, baking soda, spices, salt, and chopped Earl Grey tea leaves until well combined. 
- In a separate bowl, beat the eggs, then stir in the pumpkin puree and vegetable oil until smooth and homogeneous. 
- Pour the wet mixture into the dry ingredients, gently folding them together with a spatula until just combined. Do not overmix to keep the muffins tender. 
- Spoon the batter evenly into the prepared muffin cups, filling each about three-quarters full. 
- Bake in the preheated oven for 20 minutes, or until the muffins are golden on top and a toothpick inserted into the center comes out clean. 
- Remove the muffins from the oven and let them cool in the tin for a few minutes before transferring to a wire rack to cool completely. 
- Once cooled, enjoy these muffins with a hot cup of tea or a splash of butter for a cozy treat.
