Mini Tiramisu Eclairs

1/3 c. hot water
2 tsp. instant coffee granules
2 Tbsp. granulated sugar
2 (3 oz.) packages ladyfingers, split
1 (8 oz.) package mascarpone cheese*
1 1/2 c. powdered sugar, divided
2 Tbsp. chocolate syrup
1/2 c. semisweet chocolate morsels
1 Tbsp. butter
1 Tbsp. whipping cream

Stir together first 3 ingredients until sugar is dissolved; set aside 2 Tbsp. mixture. Brush cut sides of ladyfingers evenly with remaining coffee mixture. Stir together mascarpone cheese, 1/2 cup powdered sugar, and chocolate syrup until blended. Spoon or pipe (I would pipe) mascarpone cheese mixture evenly onto 24 cut sides of ladyfinger halves; top with remaining ladyfinger halves, cut sides down. Microwave chocolate morsels, butter, and cream at high for 30 seconds or until melted, stirring twice. Place chocolate mixture in a small heavy-duty zip-top bag; seal bag. Snip a tiny hole in 1 corner of bag, and drizzle over eclairs. Let stand until firm. Stir together reserved coffee mixture and remaining 1 cup powdered sugar, stirring until blended. Place coffee-powdered sugar mixture in a small heavy-duty zip-top bag; seal bag. Snip a tiny hole in 1 corner of bag. Drizzle eclairs evenly with coffee-powdered sugar mixture. Keep refrigerated until serving.
*1 (8 oz.) package of cream cheese, softened, may be substituted.
