How to Make Flourless Orange Cake

Preheat the Oven: Begin by preheating your oven to 160°C (320°F for fan-forced) or 180°C (355°F standard). Grease and line a 20 cm (8 inch) round cake tin to prevent sticking.
Simmer the Oranges: In a medium saucepan, combine 1 cup of water and 1 cup of caster sugar over medium heat. Stir until dissolved, then add the sliced oranges and simmer uncovered for 20-25 minutes until they’re soft and fragrant. Reserve both the oranges and syrup for later.
Blend the Mixture: Allow the cooked orange slices to cool slightly, then process them in a food processor until smooth. Add the remaining sugar, eggs, vanilla essence, almond meal, and baking powder. Pulse until everything is well combined and the mixture is smooth.
Bake the Cake: Pour the batter into the prepared cake tin and bake for 45-55 minutes, or until the top is golden and a skewer inserted into the center comes out clean. Let it cool in the tin for about 10 minutes before transferring it to a wire rack.
Glaze with Syrup: Once cooled, use a skewer to prick holes in the top of the cake and drizzle the reserved orange syrup over its surface. This adds a beautiful shine and extra flavor. For an extra treat, you can serve it with a dollop of whipped cream.

Optional: Garnish with thinly sliced orange zests for a vibrant finish.

Expert Tips for Flourless Orange Cake

Fresh Oranges Only: Always use fresh, juicy oranges for the best flavor. Avoid any that feel hard or have blemishes to ensure sweetness.
Monitor Cooking Time: Keep an eye on the baking time; every oven varies. Check your cake a few minutes early to prevent overbaking, which can dry it out.
Avoid Overmixing: When blending your ingredients, pulse just until combined. Overmixing can lead to a dense cake instead of the light, tender texture we desire in a Flourless Orange Cake.
Cool Properly: Let your cake cool completely before glazing with syrup. This ensures the glaze adheres well and enhances the orange flavor without making it soggy.
Storage Savvy: For maximum freshness, store the cake wrapped tightly in the fridge. It will keep for up to three days and tastes even better the next day!

Make Ahead Options

This Flourless Orange Cake is a fantastic choice for meal prep, making it perfect for busy weeknights or special occasions! You can prepare the batter up to 24 hours in advance by following the first three steps—simmering the oranges, blending the mixture, and pouring it into the cake tin—then cover it tightly and refrigerate until you’re ready to bake. For those looking to get a head start, the finished cake can also be stored in an airtight container in the fridge for up to three days. To maintain its quality, ensure the cake is completely cooled before storing. When you’re ready to serve, simply glaze with the reserved syrup and enjoy the same moist, delicious flavor!

How to Store and Freeze Flourless Orange Cake

Fridge: Store the cake in an airtight container for up to 3 days. This keeps it moist and flavorful. Enjoy it chilled or at room temperature for the best taste.

Freezer: Wrap the cooled cake tightly in cling film, then place it in an airtight container to freeze. It can be kept for up to 6 months. Thaw in the fridge before serving for optimal texture.

Reheating: If you prefer your cake warm, you can gently reheat individual slices in the microwave for about 10-15 seconds. Just be careful not to overheat—no one likes a dry slice of Flourless Orange Cake!

Freshness Tip: Always ensure the cake is completely cooled before wrapping to prevent moisture buildup inside your storage container.
