Preheat the oven to 180°C and line baking sheets with parchment paper.
Sift the flour, baking powder, baking soda and salt together and set it aside.
With a stand or hand mixer, cream the butter and sugars together. Scrape the bottom of the bowl.
Add the almond butter and continue to mix.
Add the eggs and vanilla essence and mix until all is well incorporated.
Add the dry ingredients to the wet ingredients and continue to mix on a low speed.
Then add the almond slivers and fold into the cookie batter.
Use a 1½ tablespoon cookie scoop to scoop the dough and then roll out into balls.
Evenly space the dough balls on the baking sheet and press each ball with a fork.
Bake for 12 minutes until golden.
Allow the cookies to cool on the baking sheet for 5 minutes then transfer it to a cooling rack.
