In a large mixing bowl, beat the softened butter and sugar until light and fluffy. This step ensures the cookies’ delicate texture. Use a hand or stand mixer with the paddle attachment.
Mix the egg and vanilla extract, and whisk for 20 – 30 seconds.
In a separate bowl, sift together the flour, baking powder, and salt. Gradually add this mixture to the wet ingredients in three batches, gently combining using a spatula or paddle attachment.
Fold in the almond meal. The dough should come together smoothly without being overly sticky.
Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
Roll the cookie dough into 1-inch or lime-sized balls. Flatten slightly with your palm of ¼ inch thickness.
Press a few sliced almonds onto the top of each cookie for added crunch and visual appeal.
Place the cookies in the preheated oven and bake for 15 – 20 minutes, or until the edges are lightly golden. Avoid overbaking to keep the centres soft.
Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
