Ingredients
For the dough:
3.5 cups of all-purpose flour
200 grams of butter or margarine
1 cup of sour cream or yogurt
3 eggs
For the cream:
3 egg whites
1 cup of sugar
1 packet of instant vanilla pudding
Instructions
Combine all the dough ingredients until you have a smooth dough. Chill it in the refrigerator for an hour.
Beat the egg whites in a mixer until they form stiff peaks. Gradually add the sugar while continuing to beat well. Once the sugar is fully mixed, briefly pause the mixer and add the instant vanilla pudding. Resume mixing on low speed until the pudding powder is fully incorporated.
Divide the dough into three portions, roll each portion out, and spread a third of the cream over it. Roll it into a log shape. It’s recommended to freeze it for at least thirty minutes; this will make it easier to slice the cookies.
Slice the dough into cookies about 1.5 centimeters thick and place them on a baking sheet with some space between them to allow for spreading.
Bake in a preheated oven at 175 degrees Celsius (medium heat) until lightly golden.
