1In medium bowl, stir baking mix, 2 tablespoons sugar, the baking powder and vanilla until blended. Add buttermilk and egg, stirring with fork or whisk until blended. In medium bowl, beat cream cheese, 1/3 cup sugar and the maple flavor with electric mixer on medium speed 1 minute or until smooth, scraping bowl occasionally. Gradually beat in whipping cream on high speed 2 minutes or until stiff peaks form.
2Heat griddle or skillet over medium-high heat (375°F). Grease griddle with vegetable oil if necessary (or spray with cooking spray before heating). For each pancake, pour 2 tablespoons batter onto hot griddle. Cook until bubbles form on top and edges are dry. Turn; cook other side until golden brown. Cool completely.
3For each whoopie pie, spread 2 heaping tablespoons maple cream on 1 pancake. Top with second pancake; gently press together. Store covered in refrigerator.
