Polish Christmas piernik bread

This is my aunt's recipe. It's really super simple but still good.

Ingredients

300g wheat flour
2 tbsp bakong powder
300g sugar
2 tbsp honey
5-6 eggs
200g butter
1 bag mix of root spices (allspice, cloves, caraway, coriander, cinnamon, nutmeg)
200g raisins
a handful of walnuts
a few dates
2 tbsp cocoa

Instruction

Basically combine all ingredients together. You can start by mixing the baking powder with the flour. The solid ingredients like the walnuts can be added last. Think about crashing/fragmenting them beforehand.

Bake for 1 hour in 160 C.
