Chocolate Vanilla Cream Sandwich Cookies

Here is a recipe that has three of my favourite things all rolled into one; chocolate, cookies and creamy vanilla frosting.  When I say frosting, think Twinkies*, that light, fluffy, vanilla goo.

To make the cookies you will need:

1 1/4 cup plain flour
1/2 cup cocoa powder
1 teaspoon baking soda
1/4 teaspoon baking powder
1/4 teaspoon salt
1 cup white sugar
1/2 cup + 2 Tablespoons butter or margarine (room temperature)
1 egg

Preheat the oven to 375 degrees F or 190 degrees C.  Line two cookie sheets with baking paper. 

You can use a food processor or an electric mixer to make the cookie dough. 
Put the flour, sugar, cocoa powder, salt, baking powder and baking soda in the bowl of the food processor.  Give it a good whiz around to mix all the dry ingredients together.  Add the butter and pulse the machine to incorporated the butter, you should get a sort of crumbly looking mix.   Add the egg and let it all whiz around until the dough comes together and you don't see any dry, floury bits. 
Using a small scoop or teaspoon, drop the cookie dough on to the lined baking sheets.

 Leave a good bit of space around each bit of dough to give the cookies room to spread out during baking.  Try to keep the cookies as round and equal in size as possible .  You are going to pair them up to make the 'sandwiches'  later.  Bake for about 8 or 9 minutes, turning the pans half way through to assure evenly baked cookies. 

Cool the cookies on a rack while you make the Cream Filling.

For the filling you will need:
1/4 cup room temperature butter or margarine
1/4 cup vegetable shortening
2 cups sifted icing sugar
2 teaspoons vanilla extract

Put the butter and shortening in a mixing bowl and beat with an electric mixer until well combined. Gradually beat in the icing sugar and add the vanilla.  If the filling is too stiff you can add a teaspoon or two of milk VERY gradually.  You do not want to make the filling too wet.   Turn the mixer on HIGH and beat, beat ,beat the filling for at least three minutes.  You want it to be light and fluffy, think Twinkies! 

Spread a good spoonful on a cool cookie and top it with a cookie of equal size.  Very gently press the cookies together to smush the frosting to the edges.  Continue icing and smushing until all the cookies have been made into sandwiches. 

Make a hot cup of coffee or tea, or a cold glass of milk and enjoy!  If you have any left, be sure to store them in an airtight container. 

*Twinkies are a snack cake made in the USA.  They are a light sponge finger filled with very fluffy frosting and are a lunch box staple for children and a guilty secret for adults.
