Shred all the carrots (I use a kitchen aide mixer attachment but for this amount, you can use a grater).
1 cups (115g) shredded carrots
Preheat the oven to 350F/177C convection (325F/163C conventional) and line a muffin pan.
Combine the flour, pecans, baking powder, cinnamon and salt in a bowl and set aside.
1 1/4 cups (150g) all-purpose flour, 1/4 cup (30g) pecans or walnuts, 1 Tbsp baking powder, 1 tsp cinnamon, 1/2 tsp salt
In a large bowl, use a whisk or an electric mixer, to combine the oil, sugar, eggs and sour cream until they're smooth.
1/2 cup (118mL) vegetable oil, 1 cup (200g) light brown sugar, 2 large eggs, 1/4 cup (56g) sour cream
Add in the dry ingredients and mix until it's just barely combined.
Fold in the carrots just until they're evenly distributed.
Fill the muffin tins just passed half way and bake for 22-25 minutes, until they spring back when you press on them gently.
