Butter a 9x13-inch baking pan or something comparable and set aside. You can even use multiple baking pans if needed.
*Note, this recipe uses a stand-up mixer but if you don’t have one, you can simply mix the ingredients together with a spatula and knead the dough by hand for about 10 minutes!
In the bowl of a stand-up mixer (with the hook attachment), add the flour, yeast and salt. Mix until combined.
In a small pot, set over medium-low heat, warm the milk, butter and honey, until butter is melted, being sure it’s not too hot (it should be lukewarm) or else the yeast won’t rise. If it does get a bit too hot, simply let it stand at room temperature until it cools down.
Pour the liquid mixture into the dry ingredients. In a small bowl, add the egg and egg yolks and beat until combined. Next, add the egg mixture to the flour mixture and knead with machine on medium speed for about 5-7 minutes, until smooth and elastic.
The dough will be quite wet and that’s ok! Rub a medium bowl with about a teaspoon of oil, (I used olive oil), and transfer the dough to the bowl. Cover with a clean kitchen towel and allow to rise for 30-40 minutes. Alternatively, cover the bowl with a lid or plastic wrap and allow to rise in the fridge for 12 to 24 hours.
