1. Combine Base Mixtures:

• Ensure your frozen whipped topping is fully thawed in the refrigerator.
• In a large mixing bowl (8-10 cup capacity or larger), stir together the sweetened condensed milk and the thawed whipped topping until well combined.
• In a separate large mixing bowl, stir together the whole milk, strawberry syrup, and vanilla extract until evenly blended and pink.

2. Combine All Ingredients:

• Carefully pour the strawberry milk mixture into the bowl containing the whipped topping/condensed milk mixture.
• Stir everything together gently but thoroughly with a whisk or spatula, making sure all the ingredients are fully combined and the mixture is uniform in color.

3. Prepare for Freezing:

• Transfer the final strawberry Frosty mixture into a large freezer-safe container (or divide between smaller containers for faster freezing).
• Cover the container(s) tightly with a lid or plastic wrap.

4. Freeze with Stirring (No-Churn Method):

• Place the container(s) into the freezer. Freeze for a minimum of 3 to 6 hours, or up to overnight, depending on your freezer temperature and container size/depth.
• Crucial Step: Stir the mixture well every 1 to 2 hours during the freezing process. Use a sturdy spoon or spatula to break up any large icy chunks forming around the edges and bottom, stirring them back into the softer center. This periodic stirring is key to achieving the smooth, frosty consistency rather than a solid block of ice. Continue stirring periodically until the mixture reaches your desired thick, spoonable, frosty consistency.

5. Serve:

• Once the Strawberry Frosty has reached your desired consistency (thick, creamy, slightly icy, like a soft-serve), spoon it into glasses or bowls.
• Enjoy immediately!
