Almond Butter Shortbread With Grape Glaze

I was reading through a past issue of Better Homes & Gardens when I came across this recipe. I had to make it immediately (well the next day, since I didn't have any grape jam on hand). Delicious! From March 2013 BHG.

• Ready In: 1 hr 16 mins
• Yields: 48 cookies

Ingredients

• 1  cup butter, softened
• 1⁄2 cup almond butter (see *note)
• 1⁄2 cup  packed brown sugar
• 1⁄2 teaspoon salt
• 2  cups all-purpose flour
• 2⁄3 cup  grape jam or 2⁄3 cup  grape preserves
•  sea salt (optional)

Directions

1. Preheat oven to 325°F.
2. In a large mixing bowl combine butter, almond butter, brown sugar, and salt. Beat with an electric mixer on medium speed until combined. Gradually add flour until incorporated.
3. On a piece of waxed paper pat dough into an 8x6-inch rectangle; cut into 48 equal pieces (about 1-inch squares). Roll pieces into balls. Place 2 inches apart on a parchment covered cookie sheet. Using a flat bottomed measuring cup dipped in flour, flatten dough balls to 1/4-inch thickness [I used my fingers instead of the cup].
4. Bake 12 minutes or until lightly browned and tops of cookies are set. Remove cookie sheet from oven. Stir jam to create a spreadable consistency. Top each cookie with a generous 1/2 tsp jam, spreading jam not quite to edges. Return to oven and bake 2 more minutes.
5. While cookies are warm, top with a sprinkle of sea salt, if desired.
6. Place cooled cookies in a single layer in an airtight container. Refrigerate up to 3 days or freeze up to 1 month. Thaw before serving.
7. *Note: Can also use natural or regular peanut butter. If you use regular peanut butter the dough will be a bit softer. Cover and chill for 30-60 minutes until firm enough to shape and cut.
