1. Make the Dough: In a large bowl, combine the warm water and yeast. Let sit for 5 minutes until foamy. Add the flour, sugar, salt, butter, and egg. Mix with a dough hook attachment on a stand mixer or by hand until a smooth, elastic dough forms.
2. Knead the Dough: Turn the dough onto a lightly floured surface and knead for 5-7 minutes, until it becomes smooth and slightly springy. Place the dough in a greased bowl, cover with plastic wrap, and let rise in a warm place for 1 hour, or until doubled in size.
3. Make the Filling: While the dough rises, combine the date paste, brown sugar, cinnamon, and cardamom in a small bowl. Stir in the melted butter until the mixture becomes sticky.
4. Assemble the Wreath: Punch down the dough, then knead until smooth. Roll out the dough into a rectangle. Spread the date filling down the center, leaving a border like a frame. Carefully roll the dough into a long rope. Gently weave the two ropes together.
5. Shape the Wreath: Gently form the braided dough into a circle, pinching the ends together to secure. Place the wreath on a greased baking sheet, seam-side down.
6. Bake the Bread: Preheat the oven to 350°F (175°C). Brush the top of the bread with butter and bake for 30-35 minutes, or until golden brown.
7. Cut the bread into slices and enjoy warm or at room temperature.
