Activate the Yeast: In a large mixing bowl, combine the warm milk and yeast. Let it sit for 5 minutes until foamy. This step ensures your Sonic Cinnasnacks rise beautifully – if no foam, your yeast might be old!

Mix Wet Ingredients: Add the granulated sugar, egg, and melted butter to the yeast mixture. Whisk until well combined. This creates the base for fluffy Sonic Cinnasnacks.

Incorporate Dry Ingredients: Gradually stir in the flour and salt. Mix until a soft dough forms. Don't overmix – you want tender Sonic Cinnasnacks, not tough ones.

Knead the Dough: Turn the dough onto a lightly floured surface and knead for 8 minutes until smooth and elastic. If sticky, add flour 1 tablespoon at a time.

Let It Rise: Place the dough in a greased bowl, cover with a clean towel, and let rise in a warm spot for 1 hour or until doubled in size. This is key for airy Sonic Cinnasnacks.

Prepare the Filling: While the dough rises, mix the softened butter, brown sugar, and cinnamon in a small bowl until smooth.

Preheat Oven: Set your oven to 350°F (175°C) and grease a baking sheet.

Roll Out Dough: Punch down the risen dough and roll it into a 12x8-inch rectangle, about 1/4-inch thick.

Spread Filling: Evenly spread the cinnamon-sugar butter over the dough, leaving a small border.

Roll and Cut: Starting from the long side, roll the dough tightly into a log. Cut into 1-inch slices using a sharp knife or floss for clean cuts.

Bake: Place slices on the prepared baking sheet, spacing them 2 inches apart. Bake for 15-20 minutes until golden brown. Your kitchen will smell like fresh Sonic Cinnasnacks!

Make the Icing: Beat the cream cheese and butter until smooth. Gradually add powdered sugar, then stir in vanilla and milk until creamy.

Serve: Drizzle the warm Sonic Cinnasnacks with icing or serve it on the side for dipping. Enjoy immediately for the best experience!
