Activate Yeast: In a small bowl, mix warm milk, instant yeast, and 1 teaspoon of granulated sugar. Let sit for 5 minutes until foamy.
Mix Wet Ingredients: In a large mixing bowl, combine melted unsalted butter, eggs, and granulated sugar. Stir in the yeast mixture until fully incorporated.
Incorporate Dry Ingredients: Gradually add all-purpose flour and salt to the wet ingredients, mixing until a dough forms. Knead on a floured surface for 8-10 minutes until smooth and elastic.
Rise: Place the dough in a greased bowl, cover with plastic wrap or a kitchen towel, and let rise for 1 hour or until doubled in size.
Roll Out Dough: On a floured surface, roll the dough into a large rectangle, about 1/4-inch thick.
Spread Filling: In a small bowl, mix brown sugar, ground cinnamon, and softened butter. Spread this mixture evenly over the dough, leaving a small border around the edges.
Roll & Cut: Starting from one long side, tightly roll the dough into a log. Slice the log into 8-12 equal pieces using a sharp knife or dental floss.
Shape Bunny Ears: Take each roll and uncoil the top slightly. Twist the unrolled ends into loops to form bunny ears.
Second Rise: Place the shaped rolls in a greased baking dish, cover, and let rise for 30 minutes.
Preheat Oven: Set your oven to 350°F (175°C).
Bake: Bake the rolls for 18-22 minutes, or until golden brown.
Glaze: In a small bowl, whisk together powdered sugar, vanilla extract, and milk or heavy cream until smooth. Drizzle over the warm rolls.
Decorate: Use pastel sprinkles, colored icing, mini chocolate chips, or cream cheese frosting to decorate the bunny faces.
Serve: Enjoy warm for the best flavor!
