Step‑by‑Step Instructions for Slow Cooker S’mores Cookie Bars
Step 1: Prep Dry Ingredients
In a mixing bowl, whisk together 2 cups of all-purpose flour, 1 teaspoon of baking soda, and ½ teaspoon of salt until well combined. This will create a light and airy structure for your Slow Cooker S'mores Cookie Bars. Set this dry mixture aside while you move on to the wet ingredients, allowing the baking soda to activate.
Step 2: Cream Wet Ingredients
In a large mixing bowl, beat together ½ cup softened butter, ½ cup granulated sugar, and ½ cup packed brown sugar until the blend is creamy and smooth. Add in 2 large eggs and 1 teaspoon of vanilla extract, continuing to mix for another minute until everything is well incorporated. This rich mixture will provide a flavorful base for your cookie bars.
Step 3: Combine Mixtures
Gradually add the dry ingredient mixture to the creamy wet ingredients, stirring gently until just combined. Do not overmix, as this can lead to tougher bars. You want to see a consistent dough forming, which will serve as the base of your Slow Cooker S'mores Cookie Bars.
Step 4: Prepare Slow Cooker
Generously spray the interior of your slow cooker with non-stick cooking spray to prevent the cookie bars from sticking. This is essential for ensuring easy removal and clean-up later. Set your slow cooker on a flat surface, ready for the cookie dough layer to be added.
Step 5: Layer Dough
Using your hands or a spatula, press the prepared cookie dough evenly into the bottom of the slow cooker, ensuring there are no gaps or thick areas. This even layer creates the perfect foundation for the melty toppings and helps achieve a delightful texture in your Slow Cooker S'mores Cookie Bars.
Step 6: Add Toppings
Evenly sprinkle 1 cup of chocolate chips over the cookie dough layer, followed by about 2 cups of marshmallows and a handful of crushed Honey Teddy Grahams. Press them down gently, ensuring that the toppings nestle into the dough for even distribution during cooking. This layering will create the signature s'mores experience.
Step 7: Cook
Cover the slow cooker with its lid and set it to cook on high for 2 to 4 hours. Start checking at the 2-hour mark for doneness; you’re looking for lightly browned edges and a firm center. Cooking times may vary based on your slow cooker model, so watch closely to achieve the perfect texture for your bars.
Step 8: Cool & Cut
Once cooking is complete, turn off the slow cooker and let the Slow Cooker S'mores Cookie Bars cool for about 10–15 minutes. Use a spatula to gently lift the edges before cutting into squares. Allowing them to cool will help the bars set, making them easier to remove and serve!
