The first time I baked this Gluten-Free Blueberry Upside-Down Cake, I was looking for a dessert that celebrated fresh blueberries in the simplest way possible. I loved the idea of juicy berries caramelizing beneath a soft lemon cake, and I couldn’t wait to flip it over after baking. The moment I turned the cake onto the serving plate, the glossy blueberry topping looked absolutely beautiful. My kitchen smelled of sweet blueberries and fresh lemon zest, and after the first bite, I knew this recipe would become a regular in my kitchen. The moist gluten-free cake paired with the vibrant blueberry layer creates a dessert that’s every bit as delicious as it is beautiful.
Why You’ll Love This Recipe
I love this recipe because it’s bursting with juicy blueberries, bright lemon flavor, and a wonderfully tender gluten-free crumb. Even people who don’t follow a gluten-free diet always ask for a second slice because the cake is incredibly soft and moist. If you’re looking for an elegant dessert that’s surprisingly easy to make, this blueberry upside-down cake is guaranteed to impress. (See the ingredients in the next page below…)

- 3 large eggs, room temperature
- 180 g (1½ cups) gluten-free plain flour blend
- 50 g (½ cup) almond flour
- 1½ teaspoons baking powder
- ½ teaspoon xanthan gum (omit if your flour blend already contains it)

- 75 g (⅓ cup) full-fat plain or Greek-style yogurt, room temperature

Step-by-Step Instructions
I always begin by preheating my oven to 180°C (350°F) and generously greasing the cake pan with softened butter. Then I sprinkle the sugar evenly across the bottom before arranging the fresh blueberries into a single layer. I try to spread them evenly because they become the beautiful topping once the cake is flipped after baking. (See the next page below to continue steps…)
Next, I prepare the lemon cake batter by rubbing the lemon zest into the sugar with my fingertips until it becomes fragrant. This little trick releases the citrus oils and gives the cake an incredible lemon aroma. I cream the butter, oil, and lemon sugar together until light and fluffy before mixing in the vanilla and eggs one at a time.
In a separate bowl, I whisk together the gluten-free flour, almond flour, baking powder, xanthan gum, and salt. I gradually fold the dry ingredients into the wet mixture, alternating with the Greek yogurt until the batter becomes smooth and creamy. I’ve learned not to overmix because that helps keep the cake wonderfully tender.
Finally, I carefully spread the batter over the blueberries, smoothing the top with a spatula. The cake bakes for 45 to 55 minutes, or until it’s golden and a toothpick inserted into the center comes out clean. I let it cool for about 15 minutes before carefully inverting it onto a serving plate. Watching the glossy blueberry topping appear is always my favorite part of making this recipe.
Pro Tips for Best Results
I tested this cake with both fresh and frozen blueberries, and while both work well, fresh blueberries create the prettiest topping because they release less moisture during baking.
One thing I learned the hard way is not to skip rubbing the lemon zest into the sugar. That simple step creates a much stronger citrus flavor throughout the entire cake.
I also recommend letting the cake cool for about 15 minutes before flipping it. If you turn it out too soon, the blueberry layer may slide around before it has a chance to set.
Common Mistakes to Avoid
The first mistake I made was overmixing the gluten-free batter. Mixing only until everything is combined keeps the cake light and tender. (See the next page below to continue…)
Another mistake is forgetting to grease the pan thoroughly. The blueberry topping contains caramelized sugar, so proper greasing makes releasing the cake much easier.
I also avoid flipping the cake after it’s completely cold. Waiting too long allows the caramelized blueberries to stick to the pan.
Finally, don’t skip the almond flour. It adds moisture and creates a softer crumb that makes the cake taste even better.
Serving Suggestions
I love serving this cake slightly warm while the blueberry topping is still soft and glossy. It’s absolutely delicious on its own.
Sometimes I add a dollop of whipped cream or a spoonful of Greek yogurt for a creamy contrast that pairs beautifully with the juicy blueberries.
When I’m entertaining, I garnish each slice with a little extra lemon zest and a few fresh blueberries for a bakery-style presentation.
Variations & Customizations
I’ve replaced some of the blueberries with raspberries, and the combination creates an even brighter berry flavor.
Another variation I enjoy includes adding a teaspoon of cinnamon to the batter for a warm, comforting twist.
Sometimes I sprinkle sliced almonds over the finished cake for a little crunch and extra texture.
How to Store, Freeze & Reheat
From my experience, this cake stays moist for up to four days when stored in an airtight container in the refrigerator.
I’ve also frozen individual slices successfully by wrapping them tightly before placing them in a freezer-safe container.
When I want to enjoy a slice, I let it thaw overnight in the refrigerator and warm it gently for a few seconds before serving.
Conclusion
This Gluten-Free Blueberry Upside-Down Cake is one of my favorite fruit desserts because it’s soft, moist, and bursting with fresh blueberry and lemon flavor. The caramelized blueberry topping makes every slice look stunning, while the tender gluten-free cake proves that gluten-free baking can be every bit as delicious as traditional recipes. Whether you’re baking it for a family dessert, brunch, or a special celebration, this cake is guaranteed to impress with both its flavor and its beautiful presentation.
