Preheat your oven to 350°F and grease a 9x13 inch pan because you still gotta bake these bars after pressure cooking. Yeah, this recipe needs a bit of both worlds.
Mix flour 1 ½ cups, granulated sugar 1 cup, brown sugar half cup packed, cinnamon 2 tsp, nutmeg and ginger quarter teaspoon each, salt half teaspoon and baking soda 1 teaspoon in a big bowl. Whisk it all together so it s even.
In another bowl, stir melted butter with the 4 eggs until they blend up good. Pour this wet mix into the dry stuff and fold gently, just till everything s combined. Don t overdo or it gets tough.
Fold in the grated carrots 2 cups then nuts and raisins if you re using [em. Spread the batter evenly in your greased pan. It s gonna look thick but that s perfect.
Put the pan inside the pressure cooker, on a rack with broth depth about an inch below the pan base so it doesn t get soggy. Seal the lid, and let the pressure build up fully. Cook on high pressure for about 25 minutes.
Once done, let the pressure natural release for 10 minutes before you open the lid. Carefully pull out the pan and let it cool before frosting.
Make your cream cheese frosting by whipping softened cream cheese, butter, powdered sugar, and vanilla together. Spread generously and slice up!
Notes
Be patient with the natural pressure release to keep your bars moist. These bars are great for gatherings and can be stored well.
