Recipe Overview

Prep Time: 15 minutes
Cook Time: 18-21 minutes
Total Time: Approximately 45 minutes
Yields: 1 9×13 inch pan
Serves: 24

Ingredients

1/2 cup butter or margarine, softened
1/2 cup white sugar
1/2 cup brown sugar
1 large egg
1/3 cup peanut butter
1/2 teaspoon baking soda
1/4 teaspoon salt
1/2 teaspoon vanilla extract
1 cup all-purpose flour
1 cup oats, preferably old fashioned
1 1/2 cups milk chocolate chips

For the Frosting:

1/2 cup powdered sugar
1/4 cup peanut butter
2-3 tablespoons milk

Equipment Needed

9×13 inch baking pan
Mixing bowls
Electric mixer or whisk
Measuring cups and spoons
Spatula

Instructions

Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking pan thoroughly. This will prevent the bars from sticking and make removal easier.
In a large mixing bowl, cream together the softened butter (or margarine), white sugar, and brown sugar until the mixture is light and fluffy. This usually takes about 3-5 minutes with an electric mixer. Proper creaming is crucial for a tender texture.
Add the egg, 1/3 cup of peanut butter, baking soda, salt, and vanilla extract to the creamed mixture. Mix everything well until thoroughly combined. Make sure there are no streaks of peanut butter or unincorporated egg.
Gradually add the flour and oats to the wet ingredients. Mix until just combined. Be careful not to overmix, as this can lead to tough bars. A few streaks of flour are okay at this stage.
Spread the batter evenly into the prepared 9×13 inch pan. Use a spatula or your fingers to ensure the batter reaches all corners of the pan and has a uniform thickness.
Bake in the preheated oven for 18-21 minutes, or until the edges are golden brown and a toothpick inserted into the center comes out with just a few moist crumbs. Keep a close eye on the bars during the last few minutes of baking to prevent them from burning.
Once the bars are done, remove them from the oven and immediately sprinkle the milk chocolate chips evenly over the hot surface. Let the bars stand for a few minutes, allowing the chocolate chips to melt from the residual heat.
After a few minutes, spread the melted chocolate evenly over the bars using a spatula. This creates a smooth, glossy chocolate layer.
Set aside the bars to cool completely. Cooling is essential before frosting, as warm bars can cause the frosting to melt and become runny.
While the bars are cooling, prepare the frosting. In a mixing bowl, combine the powdered sugar, 1/4 cup of peanut butter, and 2 tablespoons of milk. Mix until smooth. If the frosting is too thick, add the remaining tablespoon of milk, one teaspoon at a time, until you reach a creamy, spreadable consistency.
Once the chocolate layer has completely cooled and set, spread the peanut butter frosting evenly over the chocolate.
Cut the bars into squares and enjoy!

Expert Tips & Tricks

For chewier bars: Slightly underbake them. Remove them from the oven when the center still looks a bit soft. They will continue to set as they cool.
For a more intense peanut butter flavor: Use a natural-style peanut butter, but be sure to stir it well before measuring.
To prevent the chocolate from cracking when cutting: Use a warm knife. Dip the knife in hot water and wipe it dry before each cut.
Make ahead tip: The bars can be baked and cooled a day in advance. Store them in an airtight container at room temperature. Frost them just before serving.

Serving & Storage Suggestions

Serve these Peanut Butter Oatmeal Chocolate Bars as a delightful dessert, a satisfying snack, or a sweet treat alongside a cup of coffee or a glass of milk. For an extra special touch, serve them slightly chilled.

To store, keep the bars in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate them for up to a week. You can also freeze them for up to 2 months. To freeze, wrap the bars individually in plastic wrap and then place them in a freezer-safe container or bag. Thaw at room temperature before serving.
