Ingredients

- Ground nutmeg: adds complexity and a hint of nuttiness grate your own for extra punch
- Ground cloves: tiny amount for a deep spiced note use sparingly
- Baking soda: helps the bars rise just enough grab a box that is still active
- Salt: rounds out all the flavors and keeps sweetness in check
- Unsalted butter: gives rich flavor and soft crumb use real butter for best texture
- Brown sugar: infuses moisture and a gentle molasses note use dark or light both work
- Granulated sugar: balances molasses keeping the bars from being too heavy
- Molasses: classic rich gingerbread flavor look for unsulphured for best taste
- Egg: binds everything together and keeps the bars tender choose a fresh large egg

Instructions
- Prepare Your Pan:
- Line a 9x13 inch baking pan with parchment paper making sure to leave some paper hanging over the sides This will help you lift the bars out easily later
- Mix Dry Ingredients:
- Whisk together the flour ground ginger ground cinnamon nutmeg cloves baking soda and salt in a medium bowl Whisk thoroughly to evenly distribute the spices and leavening so every bite is flavorful
- Cream Butter and Sugar:
- In a large bowl use an electric mixer or a sturdy whisk to cream the unsalted butter brown sugar and granulated sugar Beat until the mixture turns light and fluffy which usually takes about two to three minutes at medium speed This step incorporates air and ensures a soft base
- Blend in Wet Ingredients:
- Add the molasses egg and vanilla extract to the creamed butter mixture Continue mixing until everything looks smooth and uniform You want the molasses to fully blend in with the sugars for deep flavor
- Combine Wet and Dry:
- Gradually sprinkle the mixed dry ingredients into your butter mixture Stir gently with a spatula or mixer just until you no longer see streaks of flour Avoid overmixing so your bars stay chewy not tough
- Spread in Pan:
- Spoon the thick batter into your lined pan Use a spatula to spread it evenly from corner to corner so the bars bake up with a level top
- Bake the Bars:
- Slide the pan into your preheated 350 F oven Bake for 18 to 20 minutes The bars should look set at the edges and still feel slightly soft in the center when you press gently with a fingertip
- Top with Candy Magic:
- Quickly remove the pan from the oven Sprinkle marshmallows assorted candies and white chocolate chips evenly over the hot surface Immediately return the pan to the oven Bake another three to five minutes just until the marshmallows puff and candies begin to melt into the top
- Cool and Slice:
- Let your bars cool completely inside the pan so the toppings set and everything holds together Once cool use the paper to lift the slab onto a cutting board Slice into sixteen squares using a sharp knife for neat edges

Whenever I make these my go to topping is a mix of random chocolates left from decorating gingerbread houses One year my little one sprinkled crushed candy canes on top by accident and now it is a family favorite twist
Storage Tips
Once sliced keep the bars in an airtight container at room temperature for up to four days If you want to keep them chewy tuck a piece of bread into the container to gently moisturize the bars Any longer and the candies may lose their texture so I recommend freezing for extended storage Stack the bars between sheets of parchment in a freezer safe box and freeze up to two months A quick warm up in the microwave makes them taste freshly baked again
Ingredient Substitutions
You can swap the egg for a flax egg if you need an egg free treat Replace the butter with a plant based stick so these bars work for dairy free diets If you run out of molasses a mix of honey and dark brown sugar can create a similar flavor though nothing quite matches molasses depth For the flour whole wheat pastry flour works for a heartier texture No mini marshmallows Try chopped up regular marshmallows or even chewy caramel bits
Serving Suggestions
Cut into tiny squares for a holiday cookie platter Use as a base for a fun ice cream sundae top with a scoop of vanilla and more candies Packable for school lunches just check your topping choice for allergens For an extra whimsical party spread turn the bars into a base for gingerbread house toppings and let kids decorate their own
Cultural and Historical Context
Gingerbread in the United States has roots in both European and American traditions Combining ginger molasses and spice dates back to colonial times and the building of gingerbread houses comes from old German holiday Customs These dessert bars capture both nostalgia and creativity by breaking down the classic house into a fun shareable treat
Seasonal Adaptations
Swirl leftover cranberry sauce into the batter before baking for a fruity twist Add a handful of chopped toasted nuts for crunch if you do not need nut free Drizzle melted dark chocolate on the cooled bars for a grown up spin

Fun with leftovers makes a great base for trifle layers You can swap candies with dried fruits for a naturally sweet version Bar texture holds up great in lunchboxes even after two days
