The successful semperit cookie

Semprit is finally done!
i mixed up
400g of corn flour (butterfly brand)
100g of custard powder(by craft,Bird )
100g of wheat flour(anchor/sauh brand)
250g of butter(buttercup)
200g of sugar(the recipe said castor but i added in normal fine sugar,it still went well)
1teaspoon of vanilla essence

Being me...always mixing all at once,however it's better to mix up the butter and sugar first then add in the flour because if not the flour would be spilling all over when trying to make the butter into small pieces.
Add in all then roll out dough and use the cookie cutter or some people use the pressed out machine to make shapes.
I used the microwave oven , at 160 degree for about 8-10minutes.
My microwave does not have a consistent flow of heat sometimes the cookies at the sides get cooked faster. However it's best to look see while shaping the others.
Do not forget to preheat the oven for about 3-4minutes pre baking.
goodluck on your Semperit cookie/biscuit.
It's my first attempt and I got it :) hope you do too.
