Our local Publix has the same cookie. They are from a recipe called Savannah Chocolate Chewies. No fat in this recipe, so I guess you can eat more.

SAVANNAH CHOCOLATE CHEWIES

2 cups chopped pecans
3 large egg whites
2 1/4 cups powdered sugar
1/4 cup plus 2 tbsp unsweetened cocoa powder
2 tbsp flour
pinch salt
3/4 tsp. vanilla
1 ounce bittersweet chocolate grated

Pre-heat oven 325 degrees F; line cookie sheet with parchment.

Toast pecans 5-10 minutes until fragrant and brown. Cool

Beat egg whites one at at time while adding powdered sugar, cocoa powder, flour, and salt. Add vanilla; beat 2 minutes on high speed.

Fold in toasted pecans and grated chocolate. Drop by heaping tablespoon on baking sheet 2-inches apart.

Bake in the middle of the oven 15-18 minutes or until dry on surface but soft in the center when pressed. DON'T OVERBAKE. Cool. Store in an airtight container for 3 days, or freeze up to 1 month.
