There’s only one way to celebrate a birthday and that’s with cookies filled with colourful sprinkles!
Preheat the oven to 175C and line two baking trays with baking paper. Add the ground linseed and water to a bowl, stir and leave for 5 minutes.
Beat the butter and sugar together until creamy and smooth, mix in the vanilla extract, pour in the linseed mixture and combine.
In a separate bowl, combine the flour, baking powder, baking soda, salt and sprinkles then add the butter mixture until a dough forms.
Divide into 10 cookie dough balls, place on to the prepared baking trays, press down using your hand to flatten and sprinkle with sugar. Bake for 13 to 15 minutes or until golden brown. Leave to cool before serving.
