Ingredients
Method
- Set the oven to 350°F (177°C), position a rack in the center, and line a 9x13-inch pan with parchment, leaving overhang for lifting later.
- In a large bowl, whisk together the flour, baking soda, ginger, cinnamon, allspice, cloves, nutmeg, pepper, and salt until evenly combined.
- In another bowl, whisk the melted butter with the brown sugar, white sugar, and molasses until smooth and glossy, then whisk in the egg, extra yolk, and vanilla.
- Scrape the wet mixture into the bowl of dry ingredients and stir with a spatula until no dry patches remain and a thick, shiny dough forms.
- Spread the dough into the prepared pan and press it into an even, smooth layer, even though it seems thin.
- Bake until the surface looks set but still soft and a toothpick inserted shows only a few moist crumbs, about 26–29 minutes.
- Place the pan on a rack and let the bars cool completely in the pan, at least 1 hour, so they can firm up.
- Beat the cream cheese and butter together until completely smooth and fluffy, scraping the bowl as needed.
- Add the powdered sugar, spices, and vanilla, then mix on low briefly before beating on high until creamy and fully blended.
- Spread the frosting over the cooled bars in an even layer and add sprinkles if using, then refrigerate for about 30 minutes to help it set.
- Lift the slab out using the parchment, transfer to a board, and slice into squares for serving.

Notes
These bars taste like a cozy afternoon wrapped in spice and warmth, especially once that creamy frosting sets on top. They’re perfect for sharing, but don’t be surprised if a few pieces quietly disappear straight from the fridge.
