This Orange Olive Oil Cake is light, moist, and full of fresh citrus flavor. It’s a gluten-free treat that’s easy to make and seriously hard to resist.
Grease or line an 8- or 9-inch round springform pan with parchment paper. Preheat the oven to 350°F (175°C).
In a large bowl, combine the sugar and egg yolks, setting the egg whites aside for now. Use a hand mixer (or whisk vigorously) to beat the mixture until it’s light and fluffy.
Add the orange zest, orange juice, vanilla extract, and olive oil to the bowl, and beat for another 2 minutes until fully incorporated.
Stir in the almond flour, baking powder, and salt, mixing until the batter is smooth and well combined.In a separate bowl, beat the egg whites until stiff peaks form.
Carefully fold the beaten egg whites into the batter using a spatula, taking your time to keep the texture light and airy.
Pour the batter into the prepared pan, smoothing the top with a spatula. Sprinkle sliced almonds evenly over the surface.
Bake for 30-32 minutes, or until the cake is golden brown and a toothpick inserted into the center comes out clean.
Allow the cake to cool in the pan for about 10 minutes before carefully removing it. Once fully cooled, dust with powdered sugar if desired.
