These chocolate gingerbread bars are a fudgy, spiced twist on classic gingerbread, baked as a single pan of thick, chewy squares instead of cookies. The dark cocoa deepens the molasses and ginger warmth, while the texture stays soft and moist for days. You need just one 9×13-inch pan and about 15 minutes of prep, making this a genuinely easy dessert for holiday trays or a cozy weekend bake.
Ingredients
- 2 cups (250 g) all-purpose flour
- 1/2 cup (50 g) unsweetened cocoa powder (natural or Dutch-process)
- 2 teaspoons ground ginger
- 1 teaspoon ground cinnamon
- 1/2 teaspoon ground cloves
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 1/2 cup (113 g) unsalted butter, melted and slightly cooled
- 1/2 cup (100 g) packed dark brown sugar
- 1/2 cup (170 g) molasses (not blackstrap)
- 1 large egg, room temperature
- 1/2 cup (120 ml) buttermilk, room temperature
- 1 teaspoon vanilla extract
- 1 cup (170 g) semi-sweet chocolate chips (optional, for topping)
Instructions
- Preheat your oven to 350°F (175°C). Line a 9x13x2-inch metal baking pan with parchment paper, leaving overhang on the long sides for easy lifting.
- In a medium bowl, whisk together the flour, cocoa powder, ginger, cinnamon, cloves, baking soda, and salt. Set aside.
- In a large bowl, whisk the melted butter, brown sugar, and molasses until smooth. Whisk in the egg, buttermilk, and vanilla until fully combined.
- Pour the dry ingredients into the wet mixture and stir with a spatula just until no streaks of flour remain. Fold in the chocolate chips if using.
- Scrape the batter into the prepared pan and spread it evenly. Bake for 22–27 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs (not wet batter). The edges will look set and slightly pulled from the pan.
- Let cool completely in the pan on a wire rack before slicing into squares. For cleaner cuts, chill the bars for 30 minutes before slicing.
Tips
- Use real molasses, not blackstrap. Blackstrap is more bitter and less sweet, which can make the bars taste harsh. Light or dark molasses (like Grandma’s or Brer Rabbit) works best.
- Don’t overmix the batter. Overmixing develops gluten and makes the bars tough. Stir until just combined, even if a few small lumps remain.
- Adjust for your pan material. If you use a glass or dark nonstick pan, lower the oven temperature by 25°F (15°C) and start checking at 20 minutes, as those pans brown faster and hold heat longer.
- Check doneness early. Ovens vary, so start testing at 20 minutes. The toothpick should have a few moist crumbs, not be completely clean—overbaking dries out the bars.
Serving Suggestions
Serve these bars as-is for a snack, or dress them up for dessert. Dust with powdered sugar, drizzle with a simple glaze (1 cup confectioners’ sugar + 2 tablespoons milk), or top with a scoop of vanilla ice cream and warm chocolate sauce. They also pair beautifully with coffee or mulled cider.
Variations
- Spice swap: Replace the cloves with 1/2 teaspoon allspice or add a pinch of black pepper for a peppery kick.
- Add-ins: Fold in 1/2 cup chopped crystallized ginger or toasted pecans along with the chocolate chips.
- Frosting: Spread a cream cheese frosting (4 oz softened cream cheese, 2 tbsp butter, 1 cup powdered sugar, 1 tsp vanilla) over the cooled bars.
- Gluten-free: Substitute the all-purpose flour with a 1:1 gluten-free baking flour blend. The texture will be slightly more crumbly but still delicious.
Storage and Reheating
Store the bars in an airtight container at room temperature for up to 4 days. They also freeze well for up to 3 months—wrap tightly in plastic wrap and foil, then thaw overnight in the fridge. To reheat, warm individual bars in the microwave for 10–15 seconds or in a 300°F (150°C) oven for 5 minutes to restore softness.
Frequently Asked Questions
Can I use white sugar instead of brown? Yes, but the bars will be slightly less moist and have a less deep flavor. Dark brown sugar adds more moisture and molasses notes, so it’s worth using if you have it.
Can I make these in an 8×8-inch pan? Yes, but the batter will be about twice as deep. Bake at 350°F (175°C) for 35–40 minutes, and check with a toothpick. The bars will be thicker and need more time; start checking at 30 minutes.
Why are my bars dry? Overbaking is the most common cause. The toothpick should have a few moist crumbs, not come out clean. Also, measure flour by spooning it into the cup and leveling off—scooping packs in extra flour.
Can I use Dutch-process cocoa? Yes, but since it’s less acidic, the baking soda won’t react as much. The bars will be slightly less risen but still tender. If using Dutch-process, you can add 1/2 teaspoon baking powder to help lift.
Can I skip the buttermilk? You can make a quick substitute: add 1 tablespoon lemon juice or white vinegar to 1/2 cup milk, let it sit for 5 minutes, then use. Or use plain yogurt thinned with a little milk.
How do I get clean slices? Chill the bars completely in the pan for 30 minutes, then lift out with the parchment and slice with a sharp knife. Wipe the knife clean between cuts.
