Preheat your oven to 350°F (175°C).
Cream the softened butter, granulated sugar, and powdered sugar until light and fluffy (about 3-5 minutes).
Beat in the beaten egg, vanilla extract, almond extract, and Butter Buds until smooth.
In another bowl, whisk together the flour, cream of tartar, baking soda, salt, and chopped almonds.
Gradually mix the dry ingredients into the wet ingredients until just combined.
Portion the dough onto prepared baking sheets, leaving 2 inches between each cookie.
Bake for 12-15 minutes, or until edges are lightly golden.
Cool on the baking sheets for 5 minutes, then transfer to a cooling rack.
