Double decker sandwich cookies

Double decker sandwich cookies make the perfect decadent snack. Chocolate chip cookies sandwiched with frosting.

Sometimes an afternoon calls for a sweet treat. This is particularly the case in the winter when the days are grey and the sun never seems to appear. Days when the wind is whistling around the house and the rain lashing down outside. On days like this the soothing ritual of making a cup of tea in the afternoon is ideal. Serve the tea from a teapot and pour into cups when it has had a chance to brew. Set out a tempting selection of cakes and biscuits on a plate and sit down and enjoy. The mere act of taking a break acts as a pick me up, distracting you from the weather outside.

Everyone is familiar with a Double Decker. Not the bus, the chocolate bar inspired by the bus which contains two layers. The bottom layer of milk chocolate covered cereal crispies contrasts with a top layer of whipped nougat.The whole bar is enrobed in chocolate. Double Deckers have been around since the seventies are are still popular today. Recently I was sent a few recipes using double deckers to try out. I thought I would make the double decker sandwich cookies as I knew they would appeal to my son.

The weather has suddenly taken a turn for the worse. What was a mild November has become wintry with a passion. The last few days have seen howling gales, lashing rain and frost. The days seem to have been endlessly grey. Days like these are definitely days for baking. The bad weather can be held at bay by the smell of cooking biscuits coming from the oven. It makes the house feel warm and cosy, especially if you can hear the wind howling outside. Double Decker sandwich cookies are the perfect bake for a day like this. They are fairly easy to prepare and don’t take long to make. The smell of baking tantalises you but there is not a long wait for the bake to be ready.

The base of the double decker sandwich cookies is a chocolate chip cookie. The biscuit dough is made quite quickly and it is not long until you can place the balls of dough on baking sheets ready to bake. Do soften the butter first, it makes mixing up the dough so much quicker. Whilst the biscuits are baking the frosting can be made so it is ready to go as soon as the biscuits are cool. In my house I have to be quick as there is every possibility the warm biscuits get eaten before being finished. If you are clever you can use a piping bag to pipe the frosting onto the cool cookies. I just used a knife, it works just as well.

    How wonderful! Cookies for afternoon tea is a must! Double-deckers will probably need a double portion of tea as well. 🙂
