Ingredients Notes
While the ingredient list might seem extensive, each component contributes to the overall texture and flavor. You can find most of these items at your local grocery store or online. Feel free to substitute the dark chocolate chips with milk chocolate if you prefer a sweeter taste. For a nut-free version, omit the nuts and add more M&Ms.
Recipe Steps
Step 1
Preheat your oven to 350°F (175°C) and line a 9×13 inch baking pan with parchment paper, allowing some paper to hang over the sides for easy removal later.
Step 2
In a mixing bowl, combine the graham cracker crumbs and melted butter. Press the mixture firmly into the bottom of the prepared pan to form an even crust.
Step 3
Sprinkle a layer of chocolate chips over the crust, followed by a layer of butterscotch chips, shredded coconut, and finally, a generous layer of chopped nuts.
Step 4
Pour the sweetened condensed milk evenly over the layers. Distribute the M&Ms across the top, pressing them slightly into the mixture to ensure they adhere.
Step 5
Bake in the preheated oven for 25-30 minutes or until the edges are golden brown. Allow the bars to cool completely in the pan before lifting them out and slicing them into bars.
Storage Options
Store these cookie bars in an airtight container at room temperature for up to a week. For longer storage, you can freeze them. Place layers of parchment paper between the bars and store them in a freezer-safe container for up to three months. To enjoy, let them thaw at room temperature for about an hour or warm them quickly in the microwave.
Variations & Substitutions
Get creative by adding a drizzle of white chocolate on top for extra sweetness. For a healthier twist, substitute half of the butter with unsweetened applesauce. You can also experiment with different candy mixes or omit the coconut to suit dietary preferences.
Serving Suggestions
These bars are perfect as a festive dessert at birthday parties or holiday gatherings. Serve them alongside a scoop of vanilla ice cream for an extra indulgent treat, or pack them as a sweet surprise for your kids’ lunchbox.
Frequently Asked Questions
Can I make these cookie bars gluten-free? Absolutely! Simply replace the graham cracker crumbs with gluten-free crumbs. You can find gluten-free graham crackers at most health food stores or online. Ensure that all other ingredients are certified gluten-free.
What can I use instead of sweetened condensed milk? For those looking to cut down sugar or avoid condensed milk, a homemade condensed milk made from evaporated milk and sugar alternatives can be a suitable substitute. Although it might slightly alter the taste and texture, it still provides a gooey, delicious layer.
How can I make these cookie bars vegan? To adapt this recipe for a vegan diet, use a plant-based butter and replace the sweetened condensed milk with a coconut milk version available at most specialty stores. Substitute the chocolate chips with vegan-friendly options.
