This is a very old recipe that has been in my family for countless generations. The recipe is pretty easy to make and once you start eating them you can't stop.
They're possibly the simplest and best cookies you ever might have the fortune of eating. I swear.
Step 1: Go Get Stuff
The recipe calls for:
1/2 lb of soft unsalted butter
1/2 cup of packed brown sugar
2 egg yolks
1 tsp vanilla
2 cups of flour
Jelly (grape, strawberry, mint and apricot are crowd favorites)
Step 2: Start Mixing
In a large bowl start mixing together the sugar, butter and vanilla.
Step 3: Egg Yolks
Separating egg yolks is actually quite easy.
Crack an egg into a small bowl and gently grab around the egg yolk with your hand lifting it slightly above the bowl. All of the excess egg will drip away and you will be left with just the yolk in your hand.
Place the yolk in the large mixing bowl with the butter/sugar/vanilla mixture.
Repeat the process with the second egg.
Once the yolks are added mash them into the mixture with your wooden cooking spoon.
Step 4: Mix the Flour
Measure out a cup of flour and start to mix it into the cookie dough. When the dough starts to thicken, add the second cup of flour.
Mix until the cookie dough is a smooth light brown.
Step 5: Make Small Balls
In the palm of your hand, roll the dough into small balls of about the diameter of a quarter and place on your cookie sheet about two to three inches apart.
When all of the balls are placed, stick your thumb into the center and flatten the ball. This will create both a flatter cookie and a little crater in which you will pour the filling.
Step 6: Add the Filling
With a spoon, place a small amount of jelly (or other filling) into the center of the cookie.
Don't fill it too much because when you cook it the filling tends to bubble and spread out.
Step 7: Bake
Preheat the oven to 350 degrees and then bake the cookies for 15 minutes.
Let them cool for 5 to 10 minutes before removing them from the tray.
Step 8: Eat
Start eating them.
