Preheat oven to 350℉ (180℃)
Combine flour, cinnamon and baking soda in a medium-sized bowl. Set aside for later.
⅔ Cup All-purpose flour, 1 teaspoon Ground cinnamon, ½ teaspoon Baking soda
In a separate bowl, add the melted butter, brown sugar and corn syrup. Whisk until well combined.
¼ Cup Unsalted butter, 1 Cup Light brown sugar, ⅓ Cup Corn syrup
Add eggs to the mixing bowl and whisk until well combined.
2 Large Eggs
Add the flour/cinnamon/baking soda to the bowl and whisk until well combined.
Add the carrots, walnuts and raisins to the bowl and stir until well combined (note: walnuts and raisins are optional).
1 ¾ Cups Carrots, finely shredded, ½ Cup Walnuts, lightly toasted and chopped, ½ Cup Raisins
Pour the filling evenly into the pie crust in your pan. Use an offset spatula to spread the top smoothly. Then, put the pie on a baking sheet or a pie drip catcher before baking.
1 Crust Partially baked pie crust in pan
Bake for 30 - 35 minutes. Check the pie after 25 minutes. If the top is turning too brown, place a sheet of aluminum foil with holes cut out over the top of the pie to prevent from burning. The pie is finished when the internal temperature reaches 180℉ / 82℃ (place an instant read thermometer into the center of the pie to check the temperature).
Place on a cooling rack and allow to cool completely (approximately 1 hour).
