Preheat oven to 160 °C/ 325 °F and line a round 23 cm/ 9 inch cake pan with parchment paper.
In a large bowl mix together the dry cake ingredients except for the carrots and pecans.
Stir in the wet ingredients until smooth.
Stir in the carrots and pecans.
Pour the batter into the prepared pan and bake 60 minutes or until a toothpick inserted into the middle comes out clean.
Remove from oven and let cool completely before frosting.
For the frosting, cream together the cream cheese and whipping cream until smooth using a hand mixer.
Add in the powdered Swerve and beat just until combined.
If the frosting is too thick add in an additional 2-3 tablespoons of cream, one at a time, until the desired consistency is met.
Stir in half of the pecan pieces.
Frost the cake with the icing using an offset spatula.
Sprinkle the remaining pecans over the top and serve.
Store covered and chilled for up to 7 days.
