In your mixing bowl, add the sugar and butter together and mix on low speed for 5 mins (Make sure the flat beater is used)
Then mix on medium speed until you obtain a paste like texture
Add the egg and water
Mix again on medium speed for 3 mins
Then add the flour, hazelnut powder and praline to the mixing bowl
Mix everything together until you get a creamy texture
Place your mixture on a baking sheet and spread it out in a way to get a rough rectangle
Place another baking sheet on top, covering edge to edge and gently press it
Using a rolling pin, spread it out evenly until you obtain the desired thickness for your final product
Place the dough in the fridge for at least two hours
Take your dough out of the fridge, remove the baking sheets and place it on a floured work surface
Use your Christmas Cookies moulds and start shaping your pre-baked biscuits
Place them on a baking sheet on a baking tray
In a preheated oven at 175 degrees Celsius (347 degrees Fahrenheit) with convection on, place the tray in the middle and bake for about 10 mins, until your Christmas cookies turn golden
The remaining dough that can't be shaped, can be put back together and placed into two baking sheets, pressed, rolled, and placed back in the fridge for at least two hours before being reused
Place your baked Christmas Cookies on a cooling grid and wait for them to cool down before tasting these delicious treats!
