What I love most about this cranberry upside-down cake is how pretty it looks without needing any frosting or decorating. Once you flip it over, the cranberries create a gorgeous red topping that’s perfect for a holiday dessert table.
I usually serve it with a little homemade whipped cream, but it’s just as delicious on its own with a cup of coffee.

Ingredients for Keto Cranberry Upside Down Cake
This low-carb cranberry upside-down cake has two simple parts: a buttery cranberry topping and a soft coconut flour cake. Here’s what you’ll need:
For the Cranberry Topping
- Butter: I recommend unsalted butter to create the rich, buttery layer underneath the cranberries.
- Brown Sweetener: Use a brown sugar substitute suitable for baking. I prefer an allulose-based brown sweetener or a baking-friendly monk fruit blend. Keep in mind that different sweeteners melt and brown differently.
- Cranberries: Fresh cranberries work best for this recipe because they hold their shape and release less moisture during baking. Frozen cranberries can also be used.
For The Coconut Flour Cake
- Coconut Flour: This coconut flour is one of my favorites as it ensures our cake is wonderfully moist and soft.
- Sweetener: Use your favorite granulated low-carb baking sweetener. Allulose or a monk fruit blend works well, although the final texture and sweetness can vary depending on the product.
- Eggs: Use large, room-temperature eggs. They help bind the coconut flour batter and give the cake structure.
- Baking Powder: Helps the cake rise and creates a softer texture.
- Cinnamon: Adds a little warmth that pairs beautifully with the tart cranberries.
- Butter: Melted butter adds richness and moisture to the cake. Let it cool slightly before mixing it with the eggs.
- Salt: Balances the sweetness and brings out the other flavors.
- Vanilla Extract: Adds a lovely vanilla flavor to the cake.
- Almond Milk: Use unsweetened almond milk. It adds moisture to the batter and helps balance the absorbency of the coconut flour.
How to Make Keto Cranberry Upside Down Cake
This sugar-free cranberry cake looks impressive, but the steps are actually quite simple. You’ll prepare the cranberry topping, mix the cake batter, and bake everything together.
Prepare The Pan
Preheat your oven to 350°F (175°C).
Lightly grease the sides of a 9-inch round cake pan that’s at least 2 inches deep.
Cut a piece of parchment paper to fit the bottom of the pan and press it into place. This will make it much easier to release the cake after baking.
Make the Cranberry Topping
Add the butter to a medium saucepan over low to medium heat.
Once melted, stir in the brown sweetener and cook for about 3 minutes, stirring frequently, until the mixture is heated through and evenly combined.
The texture may vary depending on the sweetener you use, so don’t worry if it doesn’t look exactly like traditional caramel.
Carefully pour the butter mixture into the prepared cake pan and spread it evenly across the bottom.
Arrange the cranberries over the butter mixture in an even layer.
Prepare the Cake Batter
In a large mixing bowl, whisk together the room-temperature eggs, slightly cooled melted butter, almond milk, and vanilla extract.
Whisk for about 3 minutes until the mixture looks frothy and well combined.
In a separate bowl, mix the coconut flour, granulated sweetener, baking powder, cinnamon, and salt.
Gradually add the dry ingredients to the wet mixture, stirring until you have a smooth batter with no visible lumps.
The batter will thicken slightly as the coconut flour absorbs the liquid.
Assemble the Cake
Carefully pour the cake batter over the cranberries.
Use a spatula to gently spread it into an even layer, making sure the cranberries stay in place underneath.
Bake the Cranberry Cake
Transfer the cake pan to the preheated oven and bake for approximately 30 minutes.
Start checking around the 25-minute mark, since baking times may vary depending on your oven and cake pan.
The cake is ready when the top looks golden and a toothpick inserted into the center comes out clean or with a few moist crumbs.
If the center is still wet, continue baking for a few more minutes and check again.
Cool and Flip the Cake
Remove the cake from the oven and place it on a cooling rack.
Let it cool in the pan for about 10 minutes.
Carefully run a butter knife around the edges to loosen the cake.
Place a large serving plate over the cake pan, then use oven mitts to carefully flip the pan and plate together.
Slowly lift off the cake pan and gently remove the parchment paper.
If a few cranberries stick to the parchment, simply arrange them back on top of the cake.
Let the cake cool a little longer before slicing.
Tips for the Best Cranberry Upside Down Cake
Here are a few things I’ve learned that can help you get the best results:
- Use fresh cranberries when possible. They hold their shape beautifully during baking and give the cake a lovely tart flavor.
- Choose the right pan. A 9-inch round cake pan that’s at least 2 inches deep works best. Avoid a springform pan unless it’s completely leakproof, since the buttery topping can seep out.
- Don’t overmix the batter. Mix just until the ingredients are combined and there are no visible lumps.
- Check the cake before the baking time is up. Coconut flour cakes can become dry when overbaked, so start checking a few minutes early.
- Don’t let the cake cool completely in the pan. Let it rest for about 10 minutes, then carefully flip it while the cranberry topping is still warm enough to release.
- Use a large serving plate. Choose a plate that’s slightly wider than the cake so there’s enough room for the cranberry topping.
How to Store Cranberry Upside Down Cake
This gluten-free cranberry upside-down cake stores well, making it a great option when you’re preparing holiday desserts ahead of time.
Refrigerator: Place the cooled cake in an airtight container or cover it tightly with plastic wrap. Store in the refrigerator for up to 5 days.
Freezer: Once the cake has cooled completely, wrap it tightly in plastic wrap, followed by aluminum foil, or place it in a freezer-safe container. Freeze for up to 3 months.
To thaw: Transfer the frozen cake to the refrigerator overnight. Let it sit at room temperature for a short time before serving if you prefer a softer texture.
Frequently Asked Questions
Can I Use Frozen Cranberries for Cranberry Upside Down Cake?
Yes! Although I prefer fresh cranberries, frozen cranberries can also work in this recipe.
There’s no need to thaw them first. Arrange them directly over the butter and sweetener mixture before adding the cake batter.
Keep in mind that frozen cranberries may release more moisture as they bake, so the topping can turn out a little softer.
Why Is My Cranberry Upside Down Cake Soggy?
A little moisture in the cranberry topping is normal, but the cake itself shouldn’t be wet or underbaked.
Too much moisture can happen if the cranberries release extra juice or if the cake hasn’t baked long enough.
Make sure to check the center of the cake with a toothpick before removing it from the oven.
Using fresh cranberries can also help you get a more consistent result.
Can I Use Other Berries Instead of Cranberries?
Yes, you can try making this upside-down cake with other berries, such as blueberries or raspberries.
Just remember that different fruits release different amounts of moisture during baking, so the texture of the topping may change.
Can I Make This Keto Cranberry Cake Ahead of Time?
Absolutely! You can make this cranberry upside-down cake a day before serving.
Once it has cooled completely, cover it tightly and store it in the refrigerator.
I recommend taking it out of the fridge a little before serving so the cake isn’t too cold.
Can I Replace Coconut Flour with Almond Flour?
I don’t recommend replacing coconut flour with almond flour in equal amounts.
Coconut flour absorbs significantly more liquid, so making a direct substitution would change the cake’s texture.
For the best results, stick with the coconut flour listed in the recipe card.
What Can I Serve with Cranberry Upside Down Cake?
This cake is delicious on its own, but I especially love serving it with a spoonful of homemade whipped cream.
You can also add a scoop of sugar-free vanilla ice cream for a lovely holiday dessert.

Delicious! The cranberries are like little jewels encrusted in the “top”. I did use a little less sweetener, half a cup. Otherwise, I stuck to the recipe. Thank you for posting.
