Preheat your oven to 350°F (175°C).
In a large bowl, cream the softened butter and sugar together until light and fluffy.
Add the egg and vanilla extract to the creamed mixture and mix well until fully combined.
In another bowl, sift together the flour, baking powder, and salt.
Gradually add the dry ingredients to the wet mixture, stirring until just combined.
Fold in the chopped almonds gently until evenly distributed.
Drop rounded tablespoons of dough onto a parchment-lined baking sheet, spaced apart.
Bake in the preheated oven for about 10-12 minutes, or until the edges are lightly golden.
Allow the cookies to cool on the baking sheet for a few minutes before transferring them to a wire rack.
