Jam filled cookies

Melt the butter in a double boiler or in the microwave.

Once melted, mix it with the white sugar and vanilla sugar. Mix with a whisk until it is fluffy.

Then add the egg to the butter and sugar mixture. Beat with a whisk.

Mix together the flour and the yeast.

Then add the flour little by little to the butter + sugar mixture.

Start by mixing with a whisk, then switch to a spatula and finally to your hand. This allows you to knead the dough better.

Let the dough rest in the refrigerator for 1 hour.

First of all, heat your oven to 200°.

Once the dough has rested, roll it out with a rolling pin.

Roll out the dough to a thickness of 3 to 4 millimeters.

Remember to spread the dough on parchment paper or a well-floured work surface. Otherwise you won't be able to peel it off!

With a round cookie cutter, form 40 6-centimeter circles.

Then, on half of them, make an opening with a small cookie cutter. Personally, I chose a small 3cm star but do as you wish!

You can make this hole in the middle or on the side!

Bake your cookies at 200° in a hot oven for 7 minutes

When they come out of the oven, your cookies should be slightly colored and still soft in the middle.

Then let them cool on a rack.
