Trust me and make a pan of these Marshmallow Blondies with Reese's for dessert right away. The gooey marshmallow pockets and Reese's Pieces will make every single bar disappear in a hurry.
The first time I made these Reese's peanut butter blondies was years ago for a family get-together. As soon as they cooled and I cut them, the pan was empty in 5 minutes flat.
I wish I had videoed everyone hovering around just waiting for that first cut. It was madness trying to get a square!!! There was no way I could photograph them then.
Everyone raved about these bars and wanted the recipe, so I couldn't wait to share it here, too. I knew this recipe would be a winner because of how much you guys love these Reese's Peanut Butter Pudding Cookies.
Baking with Reese's Peanut Butter Cups and Reese's Pieces may be my favorite thing to do. You can't go wrong with adding either one. I mean, just look at these Reese's Rocky Road Brownies and these Ultimate Reese's Cheesecake Brownies!
Each bite of these peanut butter blonde brownies has a pocket of marshmallow cream. Add in some Reese's Pieces and chocolate chips, and it becomes one of the best blonde brownies ever!
You are going to love how soft and chewy these peanut butter bars are. If you want them to keep that soft texture, make sure you DO NOT overbake the bars. They will still taste good, but the edges will be dried out and crumbly.
How to Make Marshmallow Blondies
These peanut butter blondies are seriously so easy to mix up. Once you mix together the batter and spread it in a pan, they take less than 30 minutes to bake. If you love them, try out these butterscotch pecan blondies as well.
- Beat together the butter, peanut butter, and sugar until creamy. Add the eggs and vanilla and beat again. (full recipe at bottom)
- Add the dry ingredients and mix until combined. Stir in chocolate chips and Reese's Pieces.
- Spread half the batter in a greased pan. Drop spoonfuls of marshmallow fluff on top and spread out gently.
- Drop spoonfuls of the rest of the batter on top and then spread out with a spatula.
- Sprinkle more chocolate chips and candies on top. Bake and cool.
My biggest suggestion when you make blonde brownies is not to overbake them. Let me say that again...do not overbake these bars!
The dough will look wobbly and undone when you take it out of the oven. Just trust me, and do not keep them in the oven longer than 30 minutes. Once they cool, they will set up, and you will be able to cut them into big or small bars.
We prefer them a little underbaked, so I usually bake ours for about 25 or 26 minutes.
BruCrew Tip: If you're making these blonde brownies (or any other ones) for a bake sale, bake them for the full 30 minutes so they're not too gooey and can be cut into neat bars.

Recipe
Marshmallow Blondies
Trust me and make a pan of these Marshmallow Blondies for dessert right away. The gooey marshmallow pockets and Reese's Pieces will make every single bar disappear in a hurry.
Ingredients
- ½ cup unsalted butter
- 1 cup packed light brown sugar
- ½ cup creamy peanut butter
- 2 large eggs
- 1 teaspoon vanilla extract
- 2 teaspoons baking powder
- ½ teaspoon table salt
- 1 ½ cup all purpose flour
- 1 cup chocolate chips, divided
- 1 cup Reese's pieces, divided
- 1 cup marshmallow cream
Instructions
- Preheat oven to 350°F. Spray a 9x13 glass pan with nonstick spray.
- In a large mixing bowl, beat the butter, sugar, and peanut butter until creamy. Add the eggs and vanilla and beat again.
- Stir together the baking powder, salt, and flour. Slowly add to the butter mixture until just mixed in.
- Add ¾ cup chocolate chips and ¾ cup Reese's pieces and stir gently. Spread half the batter in the prepared pan.
- Drop the marshmallow cream by spoonfuls on top of the batter. Gently spread it out with a spatula.
- Drop the rest of the cookie dough on top by spoonfuls. Carefully spread out the dough using a spatula. Sprinkle with the remaining chips and candy.
- Bake 25-28 minutes. Do not overbake the brownies. The pan of dough will still look undone and wobbly when you take it out. It will set up as it cools.
- Let the blondies cool completely before cutting into bars.
Notes
- If you use a metal pan, the bake time will be around 20-22 minutes.

These look good. But, did I overlook something? Ingredient list says one cup of the chips and Reese’s pieces, divided. The instructions say to use 3/4 cup of each, and I don’t see where to use the remainder. Thanks.
Jocelyn
No, you didn't miss anything, I did. I am so sorry about that. You will sprinkle the remaining chips and candy on the top of the dough before baking. I hope you enjoy the bars!
