Soft gingerbread cookie bars baked in an 8-inch pan, topped with vanilla butter frosting and cut into tidy squares.
Look for a set center and moist crumbs; baking until the tester is bone-dry makes these bars less tender.
The frosting is part of the recipe and nutrition estimate. Optional decorative crumbs come from the baked slab; no additional cookie ingredient is necessary.

Frosting
Scale ingredients and US equivalents, including eggs. Keep cookie size, thickness, oven temperature and baking time per tray unchanged. More trays add time; weigh beaten egg for fractional batches.
Instructions
Prepare the pan and spices
- Heat oven to 350°F (175°C) conventional, or about 325°F fan. Line and lightly grease an 8-inch square pan. Whisk flour, the measured ground spices, baking powder and salt.
Make the batter
- Melt butter gently; cool until lukewarm. Whisk in molasses and brown sugar, then egg and vanilla until smooth and shiny. Fold in the dry mixture just until smooth.
Spread evenly
- Scrape into the pan and spread into the corners. This is a soft batter; no chilling or rolling is needed.
Check the center
- Bake 20–25 minutes on the center rack until the middle is set and a tester has moist crumbs without wet batter.
Cool before frosting
- Cool in the pan 15 minutes, then lift using the sling and cool on a rack about 45 minutes until completely cold.
Frost and slice
- Beat confectioners sugar with softened butter. Add 1/2 tsp heavy cream, then the remaining 1/2 tsp only if needed to make a spreadable frosting. Spread over the cold slab. Cut into 16 squares. For optional crumb topping like the photo, scatter a few crumbs from a trimmed edge over the frosting.
Chef’s Science & Pro Tips
Use the correct pan
An 8-inch square pan gives the intended thickness. A larger pan produces thinner bars and needs an earlier check.
Set without drying
Look for a set center and moist crumbs; baking until the tester is bone-dry makes these bars less tender.
A neat frosting layer
Cool completely before adding butter frosting so it stays on top instead of melting into the bars.
Storage and make-ahead
| Method | How long | What to do |
|---|---|---|
| Room temperature | During serving | Keep the frosted batch refrigerated; bring out only the portions being served. |
| Refrigeration | Up to 5 days | Store frosted bars covered in the refrigerator; let serving portions soften briefly before eating. |
| Raw freezing | Not recommended | Bake this batter promptly after mixing. |
| Baked freezing | Up to 2 months | Freeze unfrosted bars airtight; thaw wrapped and frost after thawing. |
| Restoring | 20–30 minutes | Let refrigerated bars soften at room temperature. Do not heat the frosted top. |
Notes
- The butter frosting uses a little heavy cream, added gradually for consistency. Optional decorative crumbs come from the baked slab.
- The revised cream frosting has not been kitchen-tested. Keep frosted bars covered in the refrigerator and let them soften briefly before serving.
Frequently Asked Questions
Can I use a 9-inch pan?
It makes thinner bars; start checking before 20 minutes. The stated yield and timing use an 8-inch pan.
Why did my frosting melt?
The slab was still warm. Wait until both the top and center are completely cool.
Can I prepare the slab ahead?
Yes. Store the unfrosted slab airtight up to 2 days, then frost and slice.
