These no-bake oatmeal bars combine a bit of everything we love: they are extremely easy to make, very kid-friendly, have oats for a touch of healthiness, and that magic combination of peanut butter and chocolate. The ingredients are mixed and pressed into the pan, making them great for hot weather. An irresistible snack and dessert.

Though we love the Carmelitas bars and chocolate chip oatmeal bars profusely, the idea of a no-bake snack that combines so many delicious flavors caught my eye immediately.
Things are hectic nowadays, so I love finding one-bowl recipes that make life easier and baking fun. Dumping all ingredients into a bowl and not using the oven. It's still baking, right?
Turning on the oven can be a deal-breaker when the weather gets hot.
It's during those times when these chocolate peanut butter bars with chocolate come into play.
They're especially great to make with kids, and I think the colored sprinkles have something to do with it. My nephew calls them chocolate confetti bars. But that topping is optional, of course.

Ingredient list
- Oats: they give crunch to the top layer. I use old-fashioned rolled oats (traditional oats) because they have more texture, but you can use instant or quick-cooking oats.
- Chocolate cookies: use plain cookies or wafers.
- Powdered sugar.
- Chocolate: use your favorite dark semisweet chocolate for this recipe. I like Callebaut 54% chocolate wafers or Ghirardelli Premium baking bar.
- Peanut butter: the commercial type works best for this recipe, such as Jif or Skippy peanut butter.
- Unsalted butter.
- Cream: heavy, heavy whipping, and double cream, they all work.
- Salt: I like to use kosher salt when baking. But regular table salt works just fine.
- Edible confetti or sprinkles for decoration

Type of peanut butter
Though I'm a big fan of natural products, regular commercial peanut butter, such as Jif or Skippy peanut butter, works better as it has a thicker consistency.
The idea is to make the bars firm enough to cut easily and not make a mess while eating them.
If you use a natural, more fluid peanut butter, you might need to add a tad less to achieve the same firmness. That will depend on each nut butter.

They add crunchiness and a unique flavor depending on the type of cookies you use.
I love chocolate ones, but this recipe is also great with vanilla or coconut cookies. Or be more adventurous and use a spicy one like gingersnaps.
Ganache topping
This adds a layer of chocolate flavor that is amazing if you want more of it. You can omit it, but it complements the oat bars well.
What type of chocolate can you use? I love semi-sweet, but milk chocolate is an option if you like sweeter-than-average snacks. Or a mix of both. Your choice.

Type of oats
- Old-fashioned rolled oats (traditional oats): I use them for everything because they have more texture and make chewier bars.
- Instant or quick-cooking oats: the flakes are smaller and sometimes more powdery, rendering a softer bar with less texture.
Both work fine for this recipe.

Substitutions for peanut butter
- Dulce de leche: the bars will be sweeter, and the flavor different. If you've never tried chocolate and dulce de leche together, you're in for a real treat! You can buy dulce de leche repostero Vacalin online.
- Almond butter or cashew butter: the flavor is mellower than peanut in my opinion. But similar in texture.

Click the stars to Rate this Recipe!
Ingredients
- ¾ cup traditional oats
- pinch salt
- 1 cup ground plain chocolate cookies
- ⅔ cup confectioners sugar
- 3 ounces semisweet chocolate , or ½ cup semi-sweet chocolate chips
- ¾ cup peanut butter
- 6 tablespoons unsalted butter, divided
For the ganache topping:
- 3 tablespoons cream, heavy or double
- 3 oz semisweet chocolate, chopped (or ½ cup chocolate chips)
- Sprinkles for decoration, optional
Instructions
- Have ready a buttered or sprayed 8-inch square pan lined with parchment paper.
- Heat ¾ cup peanut butter and 6 tablespoons unsalted butter until soft to mix them. I use the microwave and a large mixing bowl. If you use a small container, transfer the mixture to a large bowl.
- Stir in ¾ cup traditional oats, pinch salt, 1 cup ground plain chocolate cookies, ⅔ cup confectioners sugar and 3 ounces semisweet chocolate , finely chopped, to the peanut butter mixture.
- Mix well with a silicon or rubber spatula or a wooden spoon until no dry parts remain. It might take a few minutes. The dough will be shiny and dark.
- Put it in the prepared pan, covering it as even and as smooth as possible. You might aid yourself with the back of a spoon that is lightly dipped in water.
- Refrigerate for several hours until it solidifies, and the oats absorb liquid and become chewier.
- When you’re ready to cut the bars, take the whole thing from the pan and transfer it to a board.
- In a bowl heat 3 tablespoons cream with 3 oz semisweet chocolate until melted and smooth. I do it in the microwave in 10-second spurts, whisking well each time and making sure I don't scorch the chocolate.
- Pour it over the bars. You can spread it with a spatula or use a piping bag or fork to make a pattern.
- Sprinkle some confetti over it, if desired, before the chocolate settles.
- Keep leftovers refrigerated and well wrapped.

Oh my! As a Grandmother just now passing these onto my Grandchildren, I am going to be in big trouble with my daughter. These are so good that I only gave them half the pan to take home. Excellent!

I feel you. I'm old-school about my baking too, but with kids and the general craziness of life, you need some good, quick go-to recipes to have on hand. I like these a lot because they fit that bill while still being free from the overly processed baking short-cuts that you see in so many easy/no-bake recipes. Your dulce de leche variation idea sounds fantastic too!
Paula Montenegro says
We have to adapt our baking to craziness, so true!

Aww yeah. Get in my belly, you delicious, chocolatey treat! GET IN THERE! I am going to eat my weight in these.
