First things first! Preheat your oven to 180 degrees Celsius or 360 degrees Fahrenheit. This ensures your biscuits cook evenly and come out perfectly golden.

Line your baking sheets with non-stick baking paper. This step prevents the biscuits from sticking and makes cleanup a breeze.

Place the sliced almonds in a shallow bowl or on a plate. This makes it easy for you to coat your biscuit balls later.

In a large mixing bowl, combine the almond flour, superfine sugar, and almond essence. This step allows the flavors to mingle before adding the wet ingredients.

Gently add the large egg whites and the vanilla extract into your dry mixture. Mix with a spatula until everything comes together into a firm paste. Don’t worry; it should be a bit sticky!

With your hands, roll small balls of the mixture, about 3 cm (or 1 ¼ inch) in diameter. Next, roll these balls in the flaked almonds until they’re well coated.

Carefully place the almond-coated balls onto the lined baking sheets. Gently press down on each ball with your hand to slightly flatten them. This helps them bake evenly.

Slide the baking sheets into your preheated oven. Bake for about 12-15 minutes, watching closely until the biscuits turn a lovely light brown at the edges.

Once baked, remove the sheets from the oven and let the biscuits cool for a few minutes. After, transfer them to cooling racks to ensure they cool completely.

Once cooled, you can dust them lightly with icing sugar (if using) and enjoy! To keep them fresh, store your almond biscuits in an airtight container at room temperature.
