Why you’ll love Oreo Magic Bars
Just 5 Ingredients – A decadent easy dessert made simple with just a handful of ingredients. Find them all in your cupboard or at your local grocery store.
A year-round treat – These make the best Christmas cookie bars for your holiday dessert trays, cookie exchanges, and potlucks. They’re also great for the summertime, birthdays, and dinner parties.
Freezer-Friendly – Make them, serve them, then store the rest for up to 3 months. It’s easy enough to make a couple of batches and freeze the bars of one for a later occasion. Or just because you crave something sweet one day!
Equipment you’ll need
- Mixing Bowls – Pick one that is microwave safe (like glass) so you can melt the butter.
- Food Processor – I have a mini food processor and it does just fine (& saves cupboard space!).
- Baking Pan with lid – for easy transport & storage.
Ingredients
Below is a list of the ingredients you’ll need to gather to make this recipe, why you need them, and possible substitutions. Scroll all the way down for the full recipe card with measurements.
- Butter – I use salted butter to balance out the sugary sweetness. Melted butter helps to bind the cookie crumbles to form the crust.
- Oreo Cookies – Instead of the traditional crust made with graham cracker crumbs, we’re using crushed Oreos with their creamy center! Reserve 5 cookies for later. Crumble the rest in a food processor to fine crumbs.
- Sweetened Condensed Milk – Condensed milk is cow’s milk that has been cooked down to remove the water, with sugar added. Make sure you’re not using plain evaporated milk. You want the extra sweetness. This is what binds the bars together and gives every bar a nice gooey, chewy bite. You’ll find it in the baking aisle in a can or you can make homemade sweetened condensed milk.
- Chocolate Chips & Peanut Butter Chips – Once melted, the chocolate and peanut butter chips add to the melty gooeyness and of course give major chocolate and peanut butter flavor.
How to make Oreo Magic Bars
This section shows you how to make this recipe, with process photos showing the steps to help you visualize it. For full instructions, including amounts and temperatures, see the recipe card below.
- Step One: Crush the Oreos into a fine crumb using a food processor or add them to a large zip-top and pound them with a rolling pin.
- Step Two: Melt the butter in a microwave-safe bowl and pour it into the cookie crumbs. Stir to combine and then transfer the crumbs to the bottom of the prepared 8×11 baking dish. Press it down into an even layer with a spatula or the bottom of a measuring cup.
- Step Three: Pour the can of sweetened condensed milk over the crust, spreading it evenly. Then, sprinkle the chocolate and peanut butter chips evenly across the top.
- Step Four: Arrange the reserved broken cookies evenly over the top then bake the Oreo magic bars for 20-25 minutes in a preheated 350° oven.
- Step Five: Once gooey, bubbly, and golden, remove them from the oven and allow them to sit and cool at room temperature for about 15 minutes before slicing them into bars.
What to serve with Oreo Magic Bars
As you can imagine, these bars are pretty decadent all on their own, but if you want to get a bit excessive, a scoop of ice cream would take these over the top!
If you’ve got extra Oreos you want to use up, you could also serve them alongside an easy Oreo Dip, Oreo Cheesecake Cookies, or an Easy Oreo Dirt Cup. What a fantastic array of desserts that would be!
Tips & Suggestions
- Butterscotch chips can be used in place of peanut butter chips.
- To switch it up, try white chocolate chips instead of semi-sweet.
- Add toasted coconut for another layer of flavor.
- For extra crunch, add slivered almonds, walnuts, pecans, or peanuts on top.
- Toffee bits would be great too!
- Top with mini marshmallows for even more of a gooey topping.
- Use different Oreo flavors to change the overall taste – using golden Oreos for the crust would be a fun twist.
- If you prefer thinner bars, use a 9×13 baking dish.
How to store Oreo Magic Bars
How to store leftovers
The great thing about these bars is that they don’t need to be kept in the fridge. They will stay fresh in an airtight container on the counter at room temperature for up to 5 days.
Can I freeze Oreo cookie bars?
Definitely! I recommend cutting them first, that way you can just thaw a few at a time rather than thawing the entire batch at once.
Layer the cookie bars in a freezer bag or freezer-safe container. Place a piece of parchment paper or wax paper in between the layers so they don’t freeze stuck together. Thaw them in the fridge overnight or on the counter for a couple of hours.
FAQs
Nope! The cream helps to bind the Oreo crust and provides additional sweetness.
It’s best to allow the bars to cool before slicing. When they’re still warm (and gooey and delicious) it’s easier for them to fall apart. To get the clean lines, use a sharp knife and wipe it clean with a wet paper towel in between each slice.
When using an 8 x 11 baking dish, this makes about 15 bars. You can get a greater number of bars when using a 9×13 dish, however, they’ll be thinner. Of course, it all depends on how big or small you make them.
That’s totally up to you! These bars are amazing either way. I’d say cool them to slice them then if you want to warm them up a bit, pop them in the microwave for a few seconds.
