Chocolate Pecan Pie Babka Is the Ultimate Dessert Mash-Up

Add the yeast mixture, remaining 1/4 cup granulated sugar, 2 cups all-purpose flour, 1 large egg, 1 large egg yolk, 1 teaspoon vanilla extract, and 1/4 teaspoon kosher salt to the stand mixer. Mix on low speed until combined, stopping and scraping down the sides of the bowl a few times as needed. Continue to mix on medium speed until a soft, smooth dough forms, about 2 minutes. If the dough is very sticky, mix in more flour 1 tablespoon at a time (do not add more than 4 tablespoons).
