Preheat the oven to 350°F and line a 9×9-inch baking dish with parchment paper.
Melt the butter on the stove or in the microwave. In a mixing bowl, combine the melted butter, brown sugar, vanilla, and almond extract. Whisk until smooth.
Add the egg and egg yolk, whisking until fully blended.
Fold in the grated carrots until combined.
Add the flour, cinnamon, nutmeg, ginger, and salt to the mixture. Using a rubber spatula, fold everything together until the ingredients are fully incorporated.
Gently fold in the chopped pecans.
Pour the batter into the prepared baking dish and spread it evenly.
Bake for about 33 minutes until the edges are golden brown and the center is set.
Allow the blondies to cool completely before adding the frosting.
For the frosting, beat together the butter, cream cheese, and salt in a mixing bowl until smooth and fluffy. Add the vanilla and mix again.
Gradually add the powdered sugar, one cup at a time, mixing after each addition.
Once the blondies have cooled, frost them.
Sprinkle with extra chopped pecans. Lift the blondies out of the pan using the parchment paper.
