This is one of my favourites cookies that I often ate and made when I was very young. I still remember making this with my grandma during school holidays. We always call it Katetong but the correct one is actually Kattentongen (dutch), which means Cat's Tongue. It is called cat's tongue because of its shape. It is supposed to be sweet and crunchy. However, the recipe I share below is Cheese Katetong. I put grated parmesan cheese and I really like how it turns out. Delicious!
150 gr butter, softened at room temperature
90 gr powdered sugar
1/4 tsp baking powder
70 gr egg (white only)
1/4 tsp vanilla essence
130 gr flour, I use top flour but if you don't have this, all purpose flour should work
20 gr grated parmesan
1) Preheat the oven to 170 degree celcius. Line the baking tray with baking paper.
2) Using an electric mixer, beat the softened butter and sugar until pale and fluffy (the picture above showing the dough inside the mixing bowl is not yet pale and fluffy), approximately 5 minutes.
3) Add the white egg and vanilla essence into the mixture. Continue to beat until the dough is a little bit stiff, around 5 minutes.
4) Sift the flour, baking powder, and parmesan together and add into the mixture. Mix until smooth.
5) Put the creamy dough into an icing bag and cut the tip. Put the dough into the tray, forming a line with 5 cm length. Make sure you have enough space between the "tongues".
6) Bake in the oven for about 8 minutes, then swap the trays and bake for another 8 minutes. Bake until golden.
