• Preheat oven to 350 degrees.
• In a mixing bowl whip butter and brown sugar until light and fluffy. Add egg and vanilla. Beat until well combined.
• Sift together the flour, cocoa powder, baking soda, and salt in a separate bowl.
• Add the dry ingredients alternately with the buttermilk to the butter/sugar mixture just until combined.
• Scoop dough (about 2 Tablespoons each) onto cookies sheets. Be sure to space at least 2 inches apart to allow for spreading. (I used a medium cookie scoop and thought it was a perfect size.)
• Bake 8-10 minutes or until it springs back when touched.
• Place half of the cookies upside down. Top with a generous sized amount of strawberry whipped filling. Top with sliced strawberries. Place the second cookie on top. Smear top cookie with approximately 2 teaspoons chocolate glaze.

For Strawberry Filling:

• Place softened butter in mixing bowl. Whip for 2-3 minutes. Add 1 Tablespoon strawberry jam, confectioners sugar, flour, and vanilla. Beat on medium-high speed for about 3 minutes. Stir in the rest of the strawberry jam.

For Chocolate Glaze:

• In a microwave-safe bowl melt chocolate chips on 50% power for 1 minute. Stir  well. Continue to microwave in 15-second intervals, stirring after each time until fully melted. Stir in melted butter and agave or corn syrup. Spoon glaze over the top of each whoopie pie.
