Follow these steps to bake your Orange Almond Cake to perfection:

1. Preheat the oven: Start by preheating your oven to 350°F (175°C). Grease a 9-inch round cake pan and line the bottom with parchment paper for easy removal.
2. Prepare the oranges: Zest the oranges and set the zest aside. Juice the oranges until you have about ½ cup of juice.
3. Mix dry ingredients: In a medium bowl, combine the almond flour, baking powder, and salt. Stir to blend the ingredients evenly.
4. Beat the eggs and sugar: In a large mixing bowl, combine the eggs and granulated sugar. Use an electric mixer on medium speed to beat the mixture until it becomes pale and fluffy, about 5 minutes.
5. Incorporate wet ingredients: Add the orange zest, orange juice, vanilla extract, and melted butter to the egg mixture. Mix until well combined.
6. Combine wet and dry ingredients: Gradually fold the almond flour mixture into the wet ingredients using a spatula. Mix gently until you have a smooth batter.
7. Pour and bake: Pour the batter into the prepared cake pan. Smooth the top with a spatula. Bake in the preheated oven for 40-45 minutes, or until a toothpick inserted into the center of the cake comes out clean.
8. Cool the cake: Allow the cake to cool in the pan for about 10 minutes, then transfer it to a wire rack to cool completely.
