Decisions, decisions. They suck sometimes. I’m not talking about choosing between chocolate and vanilla, cookies and brownies, or cheese and no cheese. I’m talking about change. Change is good. Change is scary. Change is risky. And sometimes when the decisions leave you restless and confused inside, you don’t know which way to jump. Being an adult is hard. But you know what isn’t hard? These Fudgy FlufferNutter Swirl Brownies. There are no decisions here. Chocolate, peanut butter, and marshmallow fluff are in one fudgy brownie. See? No decisions. Just make them, eat them, and pretend the real world doesn’t exist.

I love making brownies because you only need one pot to make the batter. That also means you can whip up brownies at last minute with little effort. Easy decision. The hardest part is deciding how many to eat. Another decision that you don’t have to make is whether you should swirl in peanut butter or marshmallow fluff. Just swirl in both! You’re definitely going to need a glass of milk to go with these decadent treats (except I don’t like drinking a straight-up glass of milk, so I opt for morning coffee).

There’s a saying that if you can’t make a decision, flip a coin because when it’s in the air, you’ll know how you want it to land. Maybe I’ll flip some brownies.

On second thought, I’ll just eat them.

Yields 16

Fudgy Fluffernutter Swirl Brownies
Save Recipe


1/2 cup (1 stick) unsalted butter
1 1/2 ounces unsweetened chocolate, chopped into pieces
1/4 cup unsweetened cocoa powder
1 1/4 cup granulated sugar
1/4 teaspoon sea salt
1 teaspoon vanilla extract
1 egg
3/4 cup all purpose flour
1/2 cup peanut butter chips
1/4 cup marshmallow fluff
1/4 cup creamy peanut butter


  1. Preheat the oven to 350°F. Line a 9x9 with parchment paper (alternatively, grease with cooking spray).
  2. In a medium saucepan, melt the butter and chocolate until smooth. Remove from the heat and whisk in the cocoa powder, sugar, and salt (at this point the batter will be thick and granular). Whisk in the vanilla then the egg. Whisk in the flour then stir in the peanut butter chips (batter will be super thick). Scrape the batter into the baking pan and smooth the top with a spatula.
  3. In a microwavable-safe bowl or cup, warm the marshmallow fluff for 15 seconds or until easy to spread. Spoon onto of the brownie batter and swirl around with a knife. Repeat with the peanut butter.
  4. Bake 25-30 minutes or until the edges just begin to pull away from the sides of the pan and a toothpick inserted into the center comes out clean (it may have some peanut butter - that's ok). Let the brownies cool completely in the pan before cutting into squares.

    But these brownies make it a bit more bearable…

    like…a lot more. Because these brownies are like miraculous

  6. haha yea please let’s just eat these until we are in our own little world

  7. Decisions are hard. And not fun sometimes, even when you know they are for the best! But the decision to stuff my face with these brownies- well that wouldn’t be hard! LOL

  8. These brownies totally have my name written all over them! They look absolutely delicious! Thanks for the link, too!

  9. I hate change. I HATE making decisions. That’s what my husband is for. ;)

    LOVE the brownies!

  10. These brownies sound brilliant. I’m definitely giving this a try. Yum!!!

  11. Ha, I totally eat my way around being an adult. These look perfect for such occasions.

  12. I lovvvvvvve fluffer nutter anything! The combination of peanut butter and marshmallow fluff is amazing. What a great idea to add these to brownies. I can’t wait to try this recipe!

  13. I think I found the brownies I’m going to make for Memorial Day. These look beyond delicious. Yummo!

  14. As I get older I think I’m ever so slowly getting better at embracing change. And I’m more than happy to embrace these brownies asap!!

  15. Haha, that’s right, instead of picking one, it’s even better to include both ingredients. :D More the merrier. :) These brownies look really pretty. It’s going to be tough to decide how many I’m allowed to eat… Maybe forget about it for these brownies! ;)

  16. I hate being an adult *stamps feet*. Weeeeell, maybe I shouldn’t take it that far. It is pretty awesome that I have a kitchen fully stocked with bakeware and sugar. Having the freedom to whip up these uber decadent brownies whenever I want is definitely a perk. I love change too, which is why I’ve had four different jobs in the last five years. Anyhoo, enjoy more brownies until you figure it out because I know that you will :)

  17. Carla, I feel like much of the major life decisions have been taken out of my hands, are beyond my control, so I guess the smaller ones don’t seem to really get to me like they used to. That being said, I’m now going to scan your index for a brownie recipe I can make in a loaf pan, since my son requested a mint chocolate chip ice cream cake on a brownie base (I usually do an Oreo pie crust like I did while working at Baskin Robbins).
