In a large mixing bowl or in the bowl of a stand mixer combine 700 grams of flour, yeast, and salt. Add the lukewarm milk, sweetener, egg, and 2½ tablespoons of butter. Using the dough hook, mix until the flour is completely incorporated, about 2-3 minutes. If the dough seems sticky, add up to 40 grams of flour more (bit by bit). Cover the bowl with plastic wrap and let sit at room temperature for 30-60 minutes.
Make the garlic butter: combine the butter, garlic, parmesan, herbs (fresh and dried), and a pinch of salt together in a small bowl.
Place the dough on your lightly floured countertop and cut it into 4 equal pieces. Roll out one of the dough balls into a large rectangle (so working with 1 dough ball at a time) and spread ¼th of the garlic butter over the dough. Cut the rolled out dough lengthwise into 3 strips and then crosswise into 4 strips each, making 12 squares (see picture above). Stack all 12 dough squares one on top of the other. Repeat all of this with the remaining 3 dough balls and garlic butter.
Cover the bundt pan with plastic wrap, and let the bread rise in a warm place until the dough almost reaches the top, about 40-60 minutes. In the meantime preheat oven to 350F/175C.
Now it is time to bake the bread wreath. Take the plastic wrap off, slide it into the preheated oven and bake until the bread is golden brown, 30 to 40 minutes. Let stand in the pan for 5 minutes and then carefully remove it.
Optionally, brush it with melted butter, sprinkle with flaky sea salt and some extra chopped herbs.
