Activate the yeast by combining warm milk and sugar; add yeast and let sit until bubbly.

Mix flour and salt in a bowl, add the yeast mixture, eggs, and vanilla; stir until a dough forms.

Knead the dough on a floured surface for 8-10 minutes until smooth and elastic.

Incorporate softened butter into the dough until fully combined.

Let the dough rise in a greased bowl for about 1 hour until doubled in size.

Punch down the dough, roll out, spread raspberries or jam, roll tightly, and place in a greased loaf pan.

Let it rise for another 30 minutes.

Preheat oven to 350?F (175?C) and bake for 30-35 minutes until golden brown and a toothpick comes out clean.
