As today had baking on the planner, it had to be done really. We knew of a recipe that was good for holding shape in the oven, but didn't have all the ingredients, so we adapted it to make up our own version. All the boys had fun making them and were fully impressed with the result, so we are sharing it here (if you don't have smiley cookie cutters, feel free to use whatever shape you have, and just use two to sandwich together).
Ingredients (makes 16 biscuit sandwiches)
75g icing sugar (+ another 75g for filling)
150g butter (+ another 150g for filling)
225g plain flour
1/ Zest the orange and then squeeze juice from it
2/ cream icing sugar with butter
3/ add half the orange zest and juice, mix well
4/ add the flour, stir into a smooth dough
5/ Cover dough & chill in fridge for 30mins
6/ Heat oven to 180C
7/ Turn dough onto floured surface, roll until about 5mm thick.
8/ Cut out shapes & put on greased baking trays (making sure you have an even number of matching shapes)
10/ For filling, mix icing sugar, butter, zest and juice together. Sandwich biscuits together with buttercream filling. Keep refrigerated for a better texture of filling.
You could also add marmalade inside for an interesting variation.
PS there are only 8 pictured here as - wouldn't you know - our first batch were overbaked (hence the 'keep an eye on them' comment!)
