No Bake Chocolate Oatmeal Cookie Bars raw ingredients that are labeled

These sweet treats pack a seriously chocolatey punch, combining the richness of chocolate with the satisfying crunch of oats.

And because they’re not baked, they stay soft and gooey, so every bite is melt-in-your-mouth delicious.

You’ll need:

½ cup of milk
2 cups of granulated sugar
1 cup of unsalted butter
1 cup of semisweet chocolate chips
¼ cup of chopped pecans
3 cups of quick oats
½ cup of graham cracker crumbs
½ teaspoon of vanilla extract

Substitutions And Additions

NUTS: While this no-bake oatmeal bars recipe calls for chopped pecans, you can substitute this for many different kinds of nuts. If you prefer, you could use chopped almonds, walnuts, cashews, or macadamia nuts instead.

CHOCOLATE CHIPS: As with the nuts, you can substitute semisweet chocolate chips. You could use milk chocolate chips, white chocolate, butterscotch, or peanut butter chips instead.

GRAHAM CRACKER CRUMBS: You can make your own graham cracker crumbs by placing them in a Ziploc bag and using a rolling pin to crush them. You can also opt to buy store-bought graham cracker crumbs if you prefer.

Once you make the cookie bar mixture on the stove, you will press it into a baking pan to let it set before you are ready to dig in.

OUR RECIPE DEVELOPER SAYS

This is a fantastic recipe to make and freeze. Make a double batch of this great treat and keep the extras for later.

STEP ONE: Spray a 9×13-inch baking dish with nonstick cooking spray.

STEP TWO: Add milk, sugar, and butter to a medium saucepan. Bring to a boil, constantly stirring. Allow to boil for one minute, and then remove the mixture from the heat.

STEP FIVE: Pour the mixture into the prepared pan and spread in an even layer. Allow to completely cool, about 1 to 2 hours. Then, slice into cookie bars and serve!

PRO TIP:

Make sure you don’t skip the cooling time for the bars. They need time to set and it will make them much easier to cut after they cool.

How To Serve No Bake Chocolate Oat Bars

These delicious bars are a great way to satisfy your sweet tooth and fill you up when you need a snack. They resemble a granola bar and will give you a great boost of energy on the go, just like our energy bites.

Some people love to pair these bars with a tall glass of cold milk for that classic and refreshing contrast of creamy and crunchy.

Others opt for something a bit more indulgent, like freshly whipped cream or a dollop of vanilla ice cream.

We think our chocolate chip cookie bars and chocolate peanut butter bars are also the perfect treat! Make sure to add them to the ‘must-make’ list.
