In a large bowl combine 1 ½ cups all-purpose flour, ½ cup almond flour, ½ teaspoon salt, and ½ teaspoon baking powder. Mix together and set aside.
Using a stand or a hand mixer, beat 1 cup unsalted butter until smooth and creamy.
Add in 1 large egg, ¾ cup granulated sugar, and 1 teaspoon almond extract. Mix until well combined.
Add the flour mixture into the butter mixture. Mix until combined, scraping the sides of the bowl as needed.
Cover the bowl of dough and place in the refrigerator to chill for 30 minutes.
Preheat the oven to 350 degrees Fahrenheit and line a baking sheet pan with a parchment paper.
Using a small cookie scoop, scoop the cookie dough and place it on the baking sheet 2 inches apart. Gently press down the dough to flatten to about ½ inch thickness. Top with sliced almonds.
Bake for 10-12 minutes until just starting to brown along the edges.
Allow cookies to cool on the baking sheet for about 5 minutes then transfer to a wire rack to continue cooling.
