Tu B' Av is kind of the jewish Valentine's day. This year it was last friday and i decided to do some heart-shaped vanilla cookies filled with raspberry jam as a sweet surprise for Ohad.
Here it's how it's done...
250 gr. butter
120 gr. sugar
1 egg white
1 pinch of salt
2 tsp. vanilla sugar
350 gr. flour
Raspberry jam (or any other kind of jam you like)
In a bowl, beat the butter, till it is soft and creamy (i do it with an electric mixer because it's much faster). Add the sugar and continue mixing till it's fluffy. Then add the egg white, the salt, the vanilla sugar and the flour and mix with a spoon, until it is incorporated. Form a bowl, wrap it in plastic foil and put to rest in the fridge for 30 minutes.
Preheat the oven to 200 degrees celsius. Take the dough out of the fridge and roll it out with a rolling pin to about 2 mm on a well floured surface. Make sure to put some flour on the rolling pin to so that the dough will not stick to it. Cut out the cookies in heart shape or any other shape you like. You will need to make an even number of cookies, since one will be used for the top and one for the bottom.
Bake the cookies for about 8-10 minutes in the middle of the oven, then take them out and let them cool down. It is perfectly normal and intended that the cookies stay white and don't get golden. Once the cookies are cooled down, take the jam and spread it over the surface of a cookie and cover it with another cookie, so that the jam is between two cookie layers, like a sandwich.
You can sprinkle some sugar powder on the top if you like, it looks pretty and tastes delicious.
