Almond Butter Blossoms

Step 1
Preheat oven to 350 degrees F (175 degrees C).

Step 2
Beat butter and almond butter in a large mixing bowl with an electric mixer on medium-high speed until creamy, about 30 seconds. Beat in 1/2 cup sugar, brown sugar, baking soda, cream of tartar, and salt until thoroughly combined. Beat egg, milk, and vanilla extract into moist ingredients.

Step 3
Beat whole wheat flour and as much of the all-purpose flour as the mixer can handle; stir remaining flour into dough.

Step 4
Combine 3 tablespoons sugar with ground almonds in a shallow bowl. Pinch off dough and roll into 1-inch balls; roll balls in almond-sugar mixture. Place cookies 2 inches apart on ungreased baking sheets.

Step 5
Bake in the preheated oven until edges are firm and tops are cracked, 8 to 10 minutes. Immediately press a chocolate almond kiss into middle of each cookie; let cool.
