Ingredients
Method
Making the Dough
- In a large bowl, mix flour, sugar, salt, and yeast.
- Add warm milk, egg, vanilla, and softened butter. Stir until it looks shaggy, then knead for about 6 to 8 minutes until smoother.
- Cover the bowl and let it rise until puffy, about 60 to 90 minutes depending on your room temperature.
Preparing the Pan and Crumbs
- Grease a 9x13 baking pan. Press the dough evenly into the pan.
- In a bowl, mix flour, sugar, salt, and cinnamon if using. Cut in cold butter with your fingers until you have chunky crumbs.
Final Assembly and Baking
- Sprinkle the streusel all over the dough. Let the cake sit for 20 to 30 minutes while the oven heats to 350°F (175°C).
- Bake for about 25 to 35 minutes until the top is lightly golden.
- Cool for 20 minutes before slicing.
Notes
Serve in thick squares with coffee or tea. Keeps fresh for 2 days at room temperature, then refrigerate or freeze individual squares.
