1 3/4 cups all-purpose flour
1/2 tsp. baking soda
1/4 tsp. salt
1/2 cup low-sodium, low-saturated-fat butter (softened)
1 cup equivalent granulated sugar substitute
2 tsp. grated orange peel
1 tsp. vanilla extract
1 large egg
Combine flour, baking soda and salt, then set aside. Beat butter and 3/4 cup sugar substitute on medium speed until light and fluffy. Add orange peel and vanilla. Mix well. Blend in egg and beat for 1 minute. Gradually add dry mixture and beat on low speed after each addition until well blended. Wrap tightly in plastic wrap and refrigerate for 1 hour or until chilled. Preheat oven to 375°F. Roll dough to 1/4 inch thickness on lightly floured surface. Cut into heart shapes and sprinkle with remaining 1/4 cup sugar substitute. Place 2 inches apart on silicone nonstick baking mat. Apply sprinkles if desired.
Bake 6-8 minutes or until lightly browned. Remove and place on wire cooling racks until completely cooled.
