In a medium bowl whisk together flour, baking powder and salt.
In a medium bowl beat together the butter and sugar for 3 minutes or until fluffy, then beat in the egg and vanilla until combined.
Beat the dry ingredients into egg mixture on low until combined. Form into a ball (will be sticky) wrap in plastic and refrigerate 30 minutes.
Pre-heat oven to 375°F (190C). Line two large cookie sheets with parchment paper.
Remove dough from the fridge and divide into 2 parts. Roll out the first part on a well floured flat surface to 1/8" thickness and cut out shapes, do the same with the remaining dough. Place on cookie sheets and bake for approximately 7-9 minutes or until light golden brown.
Cool completely before adding creamy filling if desired. Very tasty on their own also. Enjoy!
MAPLE FILLING
Beat butter, cream, maple syrup, vanilla and maple flavouring until smooth, then beat in icing sugar and combine until smooth, and has reached desired thickness, if too thin add more icing sugar.
Notes
The cookies should be stored in an airtight container and eaten within two days are room temperature. If stored in the fridge they will last up to 5-6 days.The best way to freeze sandwich cookies is to freeze them unfilled. Freeze them in a freezer safe bag or container they will last up to 6 months in the freezer. The unbaked dough can also be frozen, place in a freezer safe bag or container.
