Ingredients Notes
For this recipe, you will need graham crackers, butter, sweetened condensed milk, and your choice of toppings such as chocolate chips, coconut flakes, and nuts. If graham crackers aren’t available, digestive biscuits make an excellent substitute. Be sure to melt the butter completely, allowing it to fully combine with the graham crackers for the best base consistency.
Recipe Steps
Step 1
Preheat your oven to 350°F (175°C) and line a 9×13-inch baking dish with parchment paper for easy removal later.
Step 2
Crush the graham crackers into fine crumbs. Melt the butter and mix it with the crumbs until fully coated, then press the mixture evenly into the base of the prepared baking dish.
Step 3
Pour the sweetened condensed milk evenly over the graham cracker crust, ensuring it covers the entire surface for uniform sweetness and binding.
Step 4
Sprinkle your chosen toppings—chocolate chips, coconut flakes, nuts, or a mix—over the condensed milk. Lightly press down to ensure they stick.
Step 5
Bake for approximately 25-30 minutes until edges are golden brown. Cool completely in the baking dish on a wire rack before slicing into bars.
Storage Options
Once cool, store your magic cookie bars in an airtight container at room temperature for up to a week. For longer storage, wrap them individually and place them in a freezer-safe bag for up to three months. To reheat, allow thawing at room temperature or warm briefly in the oven.
Variations & Substitutions
Feel free to swap ingredients to cater to dietary needs—use gluten-free graham crackers or swap condensed milk for a plant-based alternative. For a flavor twist, try adding a layer of peanut butter chips or a sprinkle of sea salt for a sweet-salty contrast.
Frequently Asked Questions
Can I use different kinds of cookies for the base?
Absolutely! If you don’t have graham crackers, digestive biscuits or even crushed Oreos can provide a different but delightful flavor profile to the base of your magic cookie bars.
How do I prevent the bars from sticking to the pan?
Lining your baking dish with parchment paper is key. Leave some paper overhanging the edges for easy lifting once the bars have cooled. This ensures minimal sticking and makes for much easier cleanup.
What is the best way to cut them neatly?
To achieve cleanly cut bars, ensure they’re completely cool before slicing. Use a sharp knife, and for best results, tip the blade in hot water between cuts, wiping it dry to prevent the toppings from sticking.
