This could be a neat project for older kids to make a product and do their own "branding"...I might keep that idea to use a few years down inshallah!
We just used a simple shortbread recipe, using a heart cutter to shape. The packaging was made from some craft paper, and some punches which we put together to hide the clear bag seal at the top.
100-150g caster sugar (the recipe actually states 50g but I tasted the dough before baking and added abit extra)
250g Plain flour
Oven approx 170 degrees C.
With your hands nead the ingredients together until they come together to make a dough. Store in the fridge for at least an hour to firm up before rolling and cutting.
Place on a greased baking tray and bake.
We baked until they were a nice yellow golden brown, approx 10 minutes. (they burn quickly...you want them to still be quite yellow)
