You'll need flour, yeast, spices, salt, butter, sugar, milk, vanilla, eggs, and chocolate chips.
Activate the yeast
Activate the yeast by mixing into warm milk with sugar. Set aside for a few minutes. Once activated, mix in the eggs and vanilla.
Add wet to dry
Add the wet ingredients to the dry ingredients in the bowl of a stand mixer.
Knead the dough
With the dough hook, mix until the dough is fully combined. Add a few pieces of butter at a time, then mix on high speed until smooth and passes the windowpane test.
Allow the dough to rise overnight in the fridge or for one hour at room temperature.
Mix in the chocolate
Spread the dough out onto a lightly floured surface then add the chocolate chips to the center. Fold the edges of the dough over the chocolate chips and gently knead until evenly distributed.
Divide the dough into 12 equally sized balls and place in a 9x13 pan. Proof for 30 minutes and then pipe the crosses. Bake at 350 F for 20 minutes.
Brush with sugar syrup
Brush the buns with a sugar syrup immediately when they come out of the oven.
Serve warm for Easter brunch!
