In the bowl of a stand mixer using paddle attachment or using a handheld mixer, whisk butter and brown sugar together until the mixture turns pale and fluffy on high speed. About 3 minutes.
¾ cup Butter, unsalted, 1 cup Light Brown Sugar
Now sift in all the dry ingredients over wet. This is how I do it, you can also sift all the dry ingredients first in a different bowl and then add them here. Mix on low speed first so that the dry ingredients don't powder your face. ;) Then mix on med speed just until combined and your dough is formed.
1 and ¾ cups All purpose flour, ½ teaspoon Baking Powder, ½ teaspoon Baking Soda, ¼ teaspoon Salt, 2 and ½ teaspoon Ground Cinnamon, ¼ teaspoon Ground Nutmeg, ¼ teaspoon Ground Ginger, ¼ teaspoon Ground Allspice
Next goes in the egg and vanilla. Beat on med-high speed till the mixture turns fluffy again, for about 2 minutes. Add in the blotted carrots and combine at low speed.
1 medium Egg, 1 teaspoon Pure vanilla extract, ½ cup (75 gms) Finely grated Carrots
