Streusel (Kruszonka)
Kruszonka is the crumb topping used to sweeten and add crunchy crumble to everything from yeast baking to coffee cakes. Make this up to a week ahead of time and keep airtight in the fridge.

- 7 tbsp confectioners’ sugar
- ¼ cup granulated sugar
- 9 tbsp unsalted butter room temperature
In a medium mixing bowl, whisk together the flour, confectioners’ sugar, and granulated sugar.
Use your hands to rub the butter into the dry ingredients until you have a crumbly texture and no visible pockets of butter remain.
Chill for at least 20 minutes in the fridge before using in your recipes, or store airtight in the fridge for up to a week.
