Moist Gluten Free Gingerbread Cake
A tender, deeply spiced gingerbread cake that happens to be gluten free. It comes together in one bowl with a short list of pantry ingredients, and the molasses keeps it soft for days.
No one will guess this cake skipped the wheat flour. The crumb is moist and a little springy, with bold ginger and cinnamon hitting first, then a slow warm finish from the molasses.
Why This Gingerbread Cake Stays Moist for Days
Brown sugar and a generous pour of molasses do most of the heavy lifting here. They pull in moisture and hold it even after the cake cools, so the texture never turns dry or crumbly.
I use a gluten free flour blend that already contains xanthan gum, which gives the cake structure without any extra gums or starches. The result is a tender square that cuts cleanly and tastes just like the holiday spice cake you remember.
Ingredients
- 1/2 cup (113 g) unsalted butter, melted: salted butter works too, just reduce the added salt to a pinch.
- 3/4 cup (150 g) packed brown sugar: light or dark both work. Dark gives a slightly deeper caramel note.
- 1/2 cup (170 g) unsulphured molasses: not blackstrap, which is too bitter. Grandma’s Original or Brer Rabbit mild flavor is what you want.
- 1 large egg, at room temperature
- 1 teaspoon vanilla extract
- 2 cups (280 g) gluten free all-purpose flour with xanthan gum: I use Bob’s Red Mill 1-to-1 or King Arthur Measure for Measure. A blend without a binder will turn out crumbly.
- 1 1/2 teaspoons ground ginger
- 1 teaspoon ground cinnamon
- 1/4 teaspoon ground nutmeg
- 1/8 teaspoon ground cloves
- 1 teaspoon baking soda
- 1/2 teaspoon fine sea salt
- 1/2 cup (120 ml) buttermilk, at room temperature: to make your own, stir 1 1/2 teaspoons lemon juice or white vinegar into 1/2 cup milk and let it sit 5 minutes.
Variations / Substitutions
- Dairy free: swap the butter for melted coconut oil or a plant butter stick, and use unsweetened oat milk soured with lemon juice for the buttermilk.
- Vegan: replace the egg with 1/4 cup unsweetened applesauce or a flax egg (1 tablespoon ground flax + 2 1/2 tablespoons water, rested 5 minutes). The crumb will be slightly more dense.
- Spice it up: add a scant 1/4 teaspoon fresh black pepper for a snappier bite, or a pinch of cardamom for warmth.
- Orange ginger: stir 1 tablespoon fresh orange zest into the wet ingredients and swap the vanilla for orange juice.
- Chocolate chips: fold in 1/2 cup dark chocolate chips just before baking.

How to Make Gluten Free Gingerbread Cake
Step 1: Mix the Wet Ingredients
Preheat the oven to 350°F (175°C) with a rack in the middle. Grease an 8-inch square metal pan and line the bottom with parchment paper if you want easy lifting later. In a large bowl, whisk the melted 1/2 cup butter, 3/4 cup brown sugar, 1/2 cup molasses, egg, and vanilla until smooth and no streaks of molasses remain.
The mixture will be glossy, thick, and smell intensely of warm brown sugar and rich molasses. That deep, almost smoky scent is what gives this cake its unmistakable gingerbread character.
Step 2: Whisk the Dry Ingredients
Set a sieve over the same bowl or a separate one and measure in the 2 cups gluten free flour, 1 1/2 teaspoons ginger, 1 teaspoon cinnamon, 1/4 teaspoon nutmeg, 1/8 teaspoon cloves, 1 teaspoon baking soda, and 1/2 teaspoon salt. Whisk or sift everything together right in the bowl. If your flour blend already looks aerated, a whisk is enough.
The spice blend will smell warm and familiar the second you whisk it. Fresh spices make a real difference here, since they carry nearly all the flavor.
Step 3: Combine and Bake
Pour the wet mixture into the dry ingredients and whisk just until the batter is uniform and no pockets of flour show up. Add the 1/2 cup buttermilk and whisk again until smooth and thin. Scrape the batter into the prepared pan and smooth the top.
The batter will be quite thin, which is exactly what you want. Bake for 30 to 35 minutes, until a toothpick inserted in the center comes out with moist crumbs attached, not wet batter. The whole kitchen will smell like the holidays.
Step 4: Dust and Slice the Cake
Let the cake cool in the pan on a wire rack for 10 minutes, then run a knife around the edge and carefully flip it out onto the rack to cool completely. Once cool, dust the top heavily with powdered sugar using a fine-mesh sieve. Slice into 9 equal squares with a sharp serrated knife.
Warm gingerbread is fragile, so cooling it fully makes slicing clean. Serve the squares on their own or with a cloud of whipped cream.
A Few Tips for Perfect Gluten Free Gingerbread
- Use a blend with xanthan gum already in it. Gluten free flours without a binder will make the cake sandy and crumbly. Check the label before you start.
- Do not overmix the batter. Whisk until the flour just disappears. Overworking gluten free flours can make the crumb gummy.
- Room temperature egg and buttermilk blend in more easily and help the batter rise better. If your egg is cold, set it in a cup of warm water for 5 minutes before cracking.
- The toothpick test is more reliable than bake time here. Ovens vary, and a glass pan or dark metal pan adds 3 to 5 minutes. Start checking at 28 minutes.
Bake times by pan shape:
| Pan Shape and Size | Bake Time | Check For Doneness |
|---|---|---|
| 8-inch square metal (light) | 30 to 35 mins | Toothpick with moist crumbs |
| 9-inch square metal (light) | 25 to 30 mins | Toothpick with moist crumbs |
| 9×5-inch loaf pan | 45 to 50 mins | Skewer comes out clean |
Keeping the Cake Fresh
- Refrigerate: store cooled cake tightly covered at room temperature for up to 3 days. In warm weather, move it to the fridge in an airtight container for up to 5 days. The cold firms up the crumb, so let it sit at room temperature for 10 minutes before serving.
- Reheating: a 15-second zap in the microwave brings back that just-baked softness without drying it out. Add a tiny pat of butter on top if you like.
What To Serve With Gluten Free Gingerbread Cake
A tangy dollop of crème fraîche or thick Greek yogurt cuts through the molasses richness and makes each bite feel lighter. Warm caramel sauce and a sprinkle of flaky salt turn it into a proper dessert. If you want contrast, a spoonful of lemon curd adds a bright, zippy note that plays beautifully against the deep spices.
Frequently Asked Questions
Can I use a different gluten free flour?
You can try, but results vary a lot. A blend without xanthan gum or another binder will turn out dry and crumbly. If you only have one without a binder, add 1/4 teaspoon xanthan gum to the dry ingredients.
What if I only have blackstrap molasses?
Blackstrap is much more bitter and less sweet. I’d use only 1/4 cup blackstrap and top up the liquid with 1/4 cup dark corn syrup or honey to balance the flavor.
Can I make this cake ahead and freeze it?
Yes. Let the cake cool completely, wrap it tightly in plastic wrap then foil, and freeze for up to 2 months. Thaw overnight in the fridge and dust with powdered sugar just before serving.
How do I make this in a loaf pan?
Use a 9×5-inch loaf pan and follow the same recipe. Bake around 45 to 50 minutes, testing with a skewer in the center. The top will crack, which is normal for loaf gingerbread.
