What do I need to use to make the frosting for these peanut butter bars?

You’re going to need creamy peanut butter, salted butter, vanilla, heavy whipping cream, and confectioners sugar to make the frosting. It’s easy to put the frosting together by combining the peanut butter and unsalted butter, beating them until fluffy before adding the rest of the ingredients, beating everything together to create the perfect frosting.

How long do the bars need to bake in the oven?

After pouring your batter into the baking dish, place it in the oven and bake the bars for a minimum of 25 minutes. You may need to leave them in a bit longer, depending on your oven and how crispy you like them. You can leave them in the oven for a maximum of 30 minutes.

Do I need to let the bars cool before I frost them?

Yes, be sure to let the bars cool down before you frost them. Remove them from the oven, set them off to the side, and wait for them to cool down. Place them on a cooling rack if you have one available to use. While you’re waiting, you can prepare the frosting and then spread it on top of the bars.

Can I add anything on top of the bars?

You can add anything you’d like on top of the bars, such as chocolate sprinkles, mini chocolate chips, or even a bit of chocolate syrup. Drizzling a bit of chocolate syrup over the peanut butter frosting will add even more flavor to these bars. It’s perfect for true peanut butter lovers.
