Lately I have realized that I am easily distracted or disorganized…or both.

I have been losing receipts and putting things down then forgetting where they are.
Those are the times I pound around the house blaming one of the kids for moving it.
But then I find it, and realize that I am the one who moved it.
The thing is our house isn’t that big and I don’t have huge messes everywhere.
Yes, there are some things that could be a little better organized.

It is just this mom brain of mine that needs some more help.

Just a few weeks ago, we were coming home from somewhere.
I don’t remember…I have forgotten that already.

Anyway, my husband had some cash from something and he handed it to me.
Joking around he laughed and said “Can I trust you with this?” It wasn’t a lot.
But it’s money.  I can be trusted with that always.  Wink, wink!!!

Well, I put it in a pocket in my purse that I don’t ever put money in.
Don’t ask.  I don’t know why either.
Fast forward a few days and my husband wants the money for something.
Do I remember where I put it?  Of course not.

I search my purse, my wallet, my jeans pocket…the van.
No money anywhere.
It’s gone.  Disappeared. Vanished.

About a week later, I was digging in my purse.  Yes, the very same one I searched earlier.
Any guesses what I found in the inside pocket, under some missing receipts.
The money.
It was there the whole time…probably laughing at me.

I can tell you one thing that I will never lose!!!
Especially brownies with a fluffy peanut butter nougat filling,
oh, and a hidden marshmallow center!!!
You didn’t think I would forget to tell you about the center, did you???

Of course not.  These were way too good to forget about.
Plus, I only have one refrigerator so they were kind of hard to lose.

Don’t make these unless you have somewhere to take them or someone to give them too!
They are super addicting!!!
I kinda really wish I had lost them…my jeans wish I had too :-)


Peanut Butter Marshmallow Brownie Cups

Prep Time: 30 minutes

Cook Time: 12 minutes

Yield: 48 mini brownie cups

Peanut Butter Marshmallow Brownie Cups

Brownie cups that have a hidden marshmallow cream center and topped with a peanut butter mousse are the perfect after dinner dessert.


1 box brownie mix (for 9×13 pan)
1/2 cup marshmallow cream
1 2/3 cups peanut butter chips (10 oz. bag, Reese's)
1 1/2 teaspoons shortening, divided
1 container Cool Whip (8 oz.)
1/4 cups chocolate chips
mini Reese's Pieces


  1. Prepare the brownie mix according to the 2 egg direction on the back of the box. Spoon 1 teaspoon into greased mini muffin tins.(I like to use Baker's Joy to grease the pan.) Bake for 12 minutes at 350*. Let the brownies cool in the pan for 2 minutes, then use a wooden tart shaper or spoon to push the centers in. Let cool 2 more minutes in the pan, then remove to wire rack and cool completely.
  2. In a small sauce pan over low heat, melt the peanut butter chips and 1 teaspoon shortening. Stir until completely smooth. Beat with mixer for 1 minute. Add the Cool Whip and beat one more minute.
  3. Spoon a small amount of marshmallow cream into each brownie cup. Spoon the whipped peanut butter mixture into a piping bag or plastic bag and swirl it on top of the marshmallow. Refrigerate until set.
  4. In a microwave safe bowl, heat the chocolate chips and 1/2 tsp. shortening for 20 seconds. Stir and repeat until melted and smooth. Place in a plastic bag and cut the tip off. Drizzle over brownie cups and top with a mini Reese's pieces. Keep refrigerated. Makes 48 mini brownies.


I use a butter knife to go around the outside of the brownie cup, making it easier to remove from the pan.

    Your story reminds of me of when I put on the first pair of jeans in the fall and find money in the pocket!!! It’s like Christmas! Speaking of Christmas, finding that marshmallow fluff surprise inside those gorgeous little cups!!! Truly yummy recipe!

    Oh gosh, I’m always forgetting stuff, especially when I’m stressed out. Seems then, my brain is just operating one lone synapse at a time and I can’t remember anything! At least you found your money! Phew, I would have freaked! Also freak-out worthy, are these brownie bites! Love the hidden marshmallow center and anything that includes Reese’s Pieces, one of the most underrated candies in my book!

    So glad I’m not alone with the Mommy Brain. I need lists and notes and I still forget stuff at the grocery store. I go in for milk, and come out $100 less and with NO milk… Sigh. At least you really can’t loose these. Literally! Can’t loose them even after 10 laps around the neighborhood. Besides, they look too good to loose.

    Distraction and disorganization are 2 wonderful characteristics when it comes to money-cuz eventually you will find it and then it’s like Christmas! Just like these treats :) (oh, just make sure you don’t keep the money in a totally inconspicuous place-lol)

    Hi. Nice blog. However, I have to say… The picture with the bitten cupcake is extremely gross. Why in the world would anybody want to see your teeth marks? Please reconsider your ideas for pictures. It would be best if you not put people through the torture of seeing such a nasty picture with your horse-like teeth marks. Thanks. O_O

    Could you possibly use a portion of creamy peanut butter in place of the chips? I have 3 jars of the stuff so I really hate to purchase peanut butter chips unless it will affect the taste or consistency of the final product. These look amazing!!!

    • says

      Ok, my first thought is yes, it will work, but it will not be the same consistency. The peanut butter chips actually work with the Cool Whip to create a nougat type filling. I would heat the peanut butter until it is creamy, then whisk in the Cool Whip. It should still set back up as the peanut butter cools, but it will still be softer. You should be able to pipe it into the brownie cups with no problem. Keep me posted on how they turn out!
