I always associate these cookie bars with the warmth of the holiday season and family traditions. I remember how comforting it felt to watch a pan of these bake in the oven, filling the kitchen with sweet, buttery aromas. What I love most is how every batch feels a little different, yet still familiar and cozy.
Why You’ll Love This Recipe
I love this recipe because it’s simple, reliable, and endlessly customizable. I don’t need fancy tools or complicated steps, and I can adjust the toppings based on my mood or what I already have at home. The layers come together effortlessly, and the result is always rich, gooey, and satisfying.
Ingredients
(Tip: You’ll find the full list of Ingredients and measurements in the recipe card below.)
2 cups graham cracker crumbs
1 cup butter, melted
1 cup chocolate chips
1 cup Heath Bar bits
1 cup chopped nuts
1 cup M & Ms
1½ cups sweetened shredded coconut
1 (14-ounce) can sweetened condensed milk
Directions
I begin by preheating the oven to 350°F and lightly greasing a 9×13-inch baking dish. I combine the graham cracker crumbs with the melted butter and press the mixture firmly into the bottom of the pan to create an even crust.
I then build the layers in order. I sprinkle the chocolate chips evenly over the crust, followed by the Heath Bar bits, chopped nuts, and M & Ms. I finish by spreading the shredded coconut evenly across the top.
To complete the magic, I slowly pour the sweetened condensed milk over the entire pan, making sure it covers all the layers evenly. I bake the bars for 30 minutes, though I often bake them closer to 40 minutes because I prefer the coconut lightly toasted. Once done, I let the bars cool completely before cutting them into squares.
Servings And Timing
I usually slice this pan into 16 bars. The preparation takes me about 10 minutes, and baking takes 30 to 40 minutes. I always allow at least 1 hour of cooling time so the bars set properly and hold their shape.
Variations
I enjoy swapping the nuts for chopped pretzels when I want extra crunch. Sometimes I replace the M & Ms with chopped chocolate bars or dried fruit for a different texture. I’ve also used white chocolate chips or butterscotch chips for a sweeter variation that still works beautifully.
Storage/Reheating
I store these cookie bars in an airtight container at room temperature for up to 3 days. If I want to keep them longer, I refrigerate them for up to 7 days. When I want them warm and gooey again, I heat a bar in the microwave for about 10 seconds.
FAQs
Can I make these cookie bars ahead of time?
I often make them a day ahead because they set better and are easier to cut after resting overnight.
Can I customize the toppings?
I absolutely can. I treat this recipe as a base and adjust the toppings to suit my taste or pantry.
What pan size should I use?
I always use a 9×13-inch baking dish for the best thickness and even baking.
Can these bars be frozen?
I freeze them regularly. I wrap individual bars tightly and freeze them for up to 2 months, then thaw them at room temperature.
How do I know when they’re fully baked?
I look for golden-brown coconut on top and bubbling around the edges, which tells me they’re ready.
