Start by warming your milk in a medium bowl to about 110° Fahrenheit. Do this in either the microwave for about 30-40 seconds, or over low heat on the stove for 2 minutes.
Once milk is warm, add the active dry yeast, honey, and melted butter. Give it a gentle whisk to combine, then let that sit for a couple minutes while you continue on with the recipe.
To the bowl of an electric mixer fitted with the dough hook attachment, add the gluten-free bread flour, baking powder, and salt. Turn the mixer on low until the dry ingredients are combined.
With the electric mixer running on medium speed, slowly add the milk mixture into the flour mixture. Once the wet and dry ingredients are almost completely combined, add in the egg and egg yolk. Continue mixing to incorporate the eggs into the dough.
Once the eggs are incorporated, turn the mixer on high speed and mix the dough for 3-5 minutes, until the dough is smooth and can be easily formed into a ball.
Using a large cookie scoop or 1/3 cup measuring cup, scoop the dough into 9 balls and gently roll each ball between your palms until smooth all the way around. If the dough is sticking to your hands, lightly wet your hands with warm water before rolling.
Then, place the dinner rolls in a greased 9×9-inch baking dish and tightly cover the dish with plastic wrap. Place the rolls in a warm place (by a window, in a proving drawer, in the oven with the light on, etc) to rise for about 1 hour.
After the hour is up, remove the plastic wrap from the baking dish and preheat your oven to 350° Fahrenheit. Once the oven is hot, bake the dinner rolls for 25-30 minutes or until they’re golden brown on top. Remove the rolls from the oven and brush each roll with melted butter, then let them cool before serving.
