Peanut Butter and Chocolate Pebbles Ooey Gooey Brownie Bars

I am excited to partner with Post Pebbles as a Blogger Ambassador on this tasty and delicious recipe!

I am so glad that summer is here giving us time to reconnect as a family and make some great memories over these next couple months. One of our favorite things to do together is bake. I love recipes that can involve the kids and this recipe for Ooey Gooey Peanut Butter and Chocolate Brownie Bars certainly fits the bill.

We are big fans of Post’s Pebbles cereals and they recently came out with a brand-new flavor – Peanut Butter and Chocolate Pebbles! That’s right – peanut butter and chocolate!

When I opened the box (and this is no exaggeration) and smelled the cereal, my nose did a happy dance. Seriously. There was no doubt, this new flavor had to be used in an ooey gooey bar and they couldn’t be easier to make.

How to make Ooey Gooey Peanut Butter and Chocolate Brownie Bars

You are going to start with an 8×8 baking pan of brownies. I think that the store-bought mixes are more that good for this dessert. You’ll simply make the brownies according to the directions on the box.

Remove the brownies from the oven and, while hot, add spoonfuls of the marshmallow cream on top of the brownies. The heat of the brownies will melt the marshmallow cream and make it easy to spread.

If you find that it isn’t melting all the way, cover the pan with a sheet of foil or a silicon lid for a minute or two. This will trap the heat and help melt the marshmallow cream.

For the top layer, microwave the butter in a large bowl for 15-20 seconds, until melted. Add the 3 cups of mini marshmallows and stir to thoroughly coat. Microwave for another 45 seconds and stir until smooth. If marshmallows aren’t completely melted, microwave for another 20 seconds and re-stir.

Mix in 3 cups of Peanut Butter and Chocolate Pebbles and toss until completely coated. Drop spoonfuls of the Pebbles mix over the melted marshmallow cream layer and spread out evenly. I find it helpful to coat a disposable glove (or a sandwich baggie) with a little cooking spray and gently press down on the Pebbles mix to spread it out.

Allow the bars to cool completely before cutting. Remember, these are ooey gooey bars and the amazing gooey center can spread a bit when you cut the bars. Just have some extra napkins handy!

These Ooey Gooey Peanut Butter and Chocolate Brownie Bars have definitely become a new family favorite. I know your family will love them just as much as we do!

    WOW, these are decadent. You could probably cut them a lot smaller than 24 to a pan. And they weigh a ton. I made them for a bake sale, and two brownies to a bag was super heavy compared to my other brownies. Great flavor. I used about half a can of frosting, and frosted them warm so it melted evenly across the top just to make them look pretty as I’m not a huge frosting fan. But you definitely need to frost them as they look goofy if you don’t
