👩‍🍳 Instructions

1. Prepare the Yeast Dough

1. Activate Yeast: In a small bowl, mix the lukewarm milk, 1 teaspoon of the sugar, and the crumbled yeast. Let it sit for 5–10 minutes until foamy.
2. Combine: In a large mixing bowl, combine the flour, remaining sugar, and salt. Add the yeast mixture, the melted butter, and the egg.
3. Knead: Knead the dough vigorously for 8–10 minutes until it is smooth and elastic. The dough should be soft but not overly sticky.
4. First Rise: Place the dough in a lightly oiled bowl, cover it, and let it rise in a warm place for 45–60 minutes until it has doubled in size.

2. Make the Streusel

1. Combine Ingredients: In a separate bowl, combine the flour, sugar, vanilla, and the cold, cubed butter.
2. Mix: Use your fingertips, a pastry cutter, or a stand mixer to quickly rub the butter into the dry ingredients until coarse, crumbly streusel form. Do not overmix; you want defined crumbs, not a smooth dough. Place the streusel in the refrigerator while you assemble the cake.

3. Assemble and Bake

1. Prepare Pan: Grease and flour a $9 \times 13$ inch ($23 \times 33$ cm) baking pan.
2. Spread Dough: Punch down the risen dough and spread it evenly into the prepared baking pan.
3. Optional Filling: If using, spread a thin layer of jam over the dough.
4. Top with Streusel: Take the chilled streusel and crumble them evenly over the top of the dough.
5. Second Rise: Let the assembled cake rise in a warm place for another 20–30 minutes (this is important for a fluffy base).
6. Bake: Preheat your oven to 350°F (180°C). Bake the cake for 25–30 minutes, or until the streusel are golden brown and the yeast dough is cooked through.
7. Cool: Let the cake cool completely before slicing.
