Peanut Butter Cup Brownies In A Jar

Peanut Butter Cup Brownies In A JarI made these little beauties for my party on Monday and they were delicious!  Over the top??  Sure, but delicious anyway!  And besides being adorable, they were easy to make!  They consist of brownies, chocolate frosting, peanut butter cups and peanut butter frosting.

Scoop Brownie Mix Into JarsI purchased a 12 pack of 4 oz jelly jars and a brownie mix from Walmart.  I made the brownie batter according to the directions on the package.  Then, I greased the bottoms only of the glass jars and set them on a baking sheet.  Next, I added brownie batter to each jar.  I ended up with extra batter so the recipe could actually make more than 12 desserts.

Brownies Baked In JarsI baked the brownies for about 20 minutes at 350°F .  They were gooey when we ate them so if you like your brownies well done, you will want to bake them for longer.

Frosting On Brownies In JarsOnce the brownies were cool, I piped in store bought chocolate frosting.

Chopped Reese's Peanut Butter CupsI cut a bunch of Reese’s Peanut Butter Cups into small chunks…sorry I didn’t count how many but I think you need a little more than 1 peanut butter cup per jar.

Just put the peanut butter cup chunks on top of the chocolate frosting.

Peanut Butter FrostingTo make the peanut butter frosting, I mixed together 1 container of store bought vanilla frosting and 1 cup of peanut butter.  Then, I mixed in 1 cup of powdered sugar.  After that I added, 3 tablespoons of half-n-half and beat it until it was creamy.

Peanut Butter Cup Frosting In JarsI piped the peanut butter frosting on top of the peanut butter cups.

Peanut Butter Cup Brownies In A JarThe last thing I did was stick 1/4 of a peanut butter cup into the peanut butter frosting.  I stored them in the fridge until I was ready to serve.

Peanut Butter Cup Brownies In A JarThese were seriously delicious but very rich.  They were almost too much to eat in one sitting…not because of the size of the jars but because of how sweet they were!

Peanut Butter Cup Brownies In A Jar

by The Gunny Sack

1 brownie mix
~water, eggs and oil that are called for on the box
Preheat oven to 350°F.  Mix up the brownie batter according to the instructions on the box.  Grease the bottoms only of  4 oz jelly jars (I used 12 but had extra batter).  Put about 2 tbsp of brownie batter into each jar.  I used my cookie dough scoop and just eyeballed it.  Place the jars on a cookie sheet and bake for about 20 minutes for gooey brownies and longer for well done brownies.

Chocolate Layer:
1-16oz container of chocolate frosting
After the brownies have cooled, pipe chocolate frosting into each jar, over the brownies.

Peanut Butter Cup Layer:
About 18 Reese’s Peanut Butter Cups
Cut the peanut butter cups into chunks and place them on top of the chocolate frosting in the jars.

Peanut Butter Frosting:
1-16 oz container of vanilla frosting
1 cup peanut butter
1 cup powdered sugar
3 tbsp half-n-half
Mix together the vanilla frosting and peanut butter.  Add the powdered sugar and mix well.  Beat in 3 tbsp half-n-half until smooth and creamy.  Pipe the peanut butter frosting over the peanut butter cups in the jars.

Top each frosting peak with 1/4 of a peanut butter cup and store in the fridge until ready to serve!

    be nice to be able to print this off. I hate it when I find good recipes and not able to print them off.

    • Thanks for the feedback Rosey! I’ll update the post when I get a chance but for now I would suggest that you copy and paste the recipe onto a blank document and print it off that way. Happy Baking! ~Tonia

    Tonia, Can you tell me how to print this? Usually you have a print icon and I just print out your absolutely wonderful recipes. Thankyou Diana

    • Sorry Diana, this recipe is from my old website and doesn’t have the right formatting yet. I will email it to you so that you can print it. Have a great weekend!

  3. This looks amazing!!! I know a similar one. Make the brownies according to the box. Pour into jars. Then put one caramel in the center of each. Bake. Top with chopped pecans, hot fudge and cool whip. Serve warm. It is very good. Also for people with peanut allergies this is a nice alternative.

  4. I made this & took it to work. Everybody loved it !! Will be a keeper !!!!!

  5. looks delicious, I want

  6. Pinning this yummy looking recipe :) thank you!!

  7. This would be a decent idea if any part of the recipe was homemade. Chocolate and peanut butter is overdone enough, at least make it yourself before you post it online.

    • This would be a decent comment if any of it had been kind. Leaving rude comments is overdone enough, at least make yours original before posting!

      • Amen. I love easy cute recipes but I’m no purist like some. I can happily eat anything if it’s good and boy do these look yummy. :)
