In the bowl of an electric mixer, add eggs, pumpkin and butter.
Mix on medium speed until fully combined.TIP: Fully combined means that no single ingredient is visible but rather everything is combined into one cohesive mixture.
Add flour, sugar, baking soda, cinnamon, cloves, allspice and salt to bowl.
Mix together on low speed until almost combined.TIP: You'll want to stop mixing when a bit of dry ingredients are still visible and not fully incorporated. This will help prevent over mixing the batter in the next step which will lead to tough, instead of tender, muffins.
