Gluten Free Strawberry Upside Down Cake

This gluten free strawberry upside down cake transforms fresh strawberries into a beautifully caramelized topping beneath a tender vanilla cake. It’s a simple but impressive dessert perfect for gatherings or whenever you want a sweet treat that feels special but is easy to make. The cake stays moist and flavorful while showcasing the natural sweetness and vibrant color of the strawberries.

Ingredients

• Softened butter for greasing the pan: helps prevent sticking and encourages caramelization of the strawberries
• Caster or superfine sugar sprinkled under strawberries: draws out juices and creates a delicious syrup
• Fresh strawberries: the star of the dish, choose ripe and fragrant berries for the best flavor and color
• Caster sugar for the cake batter: sweetens while keeping the crumb light
• Eggs at room temperature: provide structure and richness
• Whole milk at room temperature: adds moisture and tenderness
• Unsalted butter melted and cooled: enriches the batter with creamy flavor
• Neutral tasting oil such as sunflower or canola: keeps the cake moist without interfering with flavor
• Vanilla bean paste or extract: gives warm vanilla notes that complement the strawberries
• Gluten free plain flour blend: use a blend without xanthan gum or other binders unless you will add your own
• Baking powder: helps the cake rise nicely
• Xanthan gum: binds ingredients and gives structure, omit if your flour blend already contains a binder
• Salt: balances sweetness and enhances flavors

Step-by-Step Instructions

Sauté the Oven and Preparation:

Adjust the oven rack to the middle position and preheat your oven to 350 degrees Fahrenheit or 180 degrees Celsius. Butter a 9-inch round cake pan thoroughly and line the bottom with parchment paper, buttering the parchment as well. This step is key to releasing the cake cleanly after baking. Avoid using a springform pan because strawberry juices can leak during cooking.

Arrange the Strawberry Base:

Evenly sprinkle ¼ cup of caster sugar across the prepared cake pan bottom. Place halved strawberries cut side down as close as possible on top of the sugar, fitting as many as you can without gaps. Use some quartered or smaller pieces to fill any small spaces. This tight packing ensures a vibrant, juicy topping. Set aside for now as you prepare the batter.

Mix the Wet Ingredients for the Cake:

In a large bowl, whisk together ¾ cup sugar, three eggs at room temperature, half a cup of whole milk, melted and warmed unsalted butter, neutral oil, and vanilla bean paste until smooth and well combined. Room temperature ingredients help the mixture emulsify better and create a tender crumb.

Combine Dry Ingredients:

In a separate bowl, whisk together the gluten free flour blend, two teaspoons baking powder, half a teaspoon xanthan gum unless your blend includes it, and a quarter teaspoon salt. This ensures even distribution of leavening and binding agents.

Create the Batter:

Slowly add the dry ingredients to your wet mixture while whisking constantly to avoid lumps. Stir until you get a smooth, somewhat runny batter with no traces of flour. This consistency helps the cake bake evenly and rise well around the strawberry layer.

Bake the Cake:

Pour the batter gently over the strawberry layer in the prepared pan. Place it in the oven and bake for about 35 to 40 minutes. The top should turn a nice golden brown and the cake will rise. Check doneness by inserting a toothpick or cake tester—it should come out clean. If the cake is browning too quickly, tent it with aluminum foil shiny side up but keep baking until fully cooked.

Cool and Unmold:

Once baked, allow the cake to cool for about 15 minutes in the pan. Then carefully invert it onto a serving platter so the strawberry layer is on top. The fruit will have created a glossy, juicy topping that makes every slice a showstopper.

Storage Tips

Once cooled completely, cover the cake tightly with plastic wrap or place in an airtight container. It stores best at room temperature for about two days to keep the strawberries juicy and cake soft. Refrigerating can dry it out but is fine if your kitchen is warm. Leftovers can be gently warmed in a low oven or microwave before serving to revive the strawberry glaze. For longer storage, slice and freeze wrapped pieces, thawing slowly before eating.

Ingredient Substitutions

If you do not have vanilla bean paste use pure vanilla extract instead but reduce the quantity slightly as it is more liquid. Use whichever neutral oil you prefer such as vegetable, canola, or light olive oil to keep the cake moist. For the gluten free flour blend, if you have one with xanthan gum included, omit the extra xanthan gum to avoid too dense a texture. Fresh or frozen strawberries work but fresh is best for maximum flavor and color.

Serving Suggestions

This cake is perfect served plain or with a dollop of softly whipped cream or a scoop of vanilla ice cream. Fresh mint leaves add a lovely contrast and aroma if you like garnishing. It pairs well with a light cup of tea or a fruity white wine for dessert. Because it is not overly sweet it can also accompany a mid-afternoon coffee or be enjoyed as a sweet snack.

Frequently Asked Questions

What type of flour is used for this cake?

A plain gluten free flour blend without xanthan gum is recommended to achieve a tender crumb and good rise.

How should the strawberries be prepared?

Fresh strawberries are hulled and cut in halves or smaller pieces to pack tightly across the base of the pan for an even fruit layer.

Why butter the parchment paper in the pan?

Buttering both the pan and the parchment helps prevent sticking and promotes caramelization of the sugar and strawberry juices.

Can I use a springform pan for baking?

It's best to avoid springform pans as strawberry juices may leak during baking. Use a standard round cake pan instead.

How do I know when the cake is done?

Bake until golden brown and a toothpick inserted into the center comes out clean. Cover with foil if browning happens too quickly.

Is xanthan gum always required in the batter?

Add xanthan gum only if your gluten free flour blend lacks binders, to provide structure and hold the cake together.
