I am not quite sure what got into me that I decided to make these brownies. But let me just be clear. These are trouble…

Like really tight pants kind of trouble.

Peanut Butter Cup Brownies

Rich, gooey, peanut butter+chocolate=my kryptonite.

Peanut Butter Cup Brownies

I kept seeing these little mini peanut butter cups around.

And eventually, I couldn’t hold back any longer. I had to bake them into something!

So I folded them into this super rich brownie batter and slathered them in peanut butter chocolate ganache. nuff said.

Peanut Butter Cup Brownies, makes 12
1 ¼ sticks of butter, cut into small pieces
1 ¼ cups sugar
¾ cup cocoa powder
2 tsp water
1 tsp vanilla
½ tsp salt
2 large eggs
1/3 cup plus 1 TBS AP flour
8 oz reese’s peanut butter cup mini’s
Peanut Butter Ganache:
2/3 cup cream
2 cups dark chocolate pieces
2 Tbs peanut butter

Preheat the oven to 325 degrees.

Prepare an 8×8” pan with tin foil (two sheets creating an x with a 2 inch overlap of foil) and then spray the foil with cooking spray.

In a medium saucepan, melt the butter until no longer foaming and the butter has browned, about 5 minutes.

While you are waiting for the butter to brown, combine the sugar, cocoa, water, vanilla and salt in the bowl of a mixer.

Add the hot butter and scrape all of the browned bits into the bowl of the mixer and then whip to combine.

With the mixer on medium, add the eggs one at a time.

Then add the flour to combine.

Add the peanut butter cups and briefly mix in.

Transfer the batter to the prepared pan and smooth with a dampened spatula.

Bake 25 minutes and remove from oven. Let cool.

When they have cooled enough to handle the pan, place it in the freezer at least 20 minutes.

To make the ganache:
In a small sauce pan, heat the milk and peanut butter until almost boiling.

Meanwhile, place the chocolate pieces in a medium heatproof bowl.

Dump the hot milk over the chocolate and leave for about 5 minutes.

IMG_0036

When you have let the chocolate and milk sit and they look melted, whisk vigorously with a metal whisk until thick and glossy.

Let the ganache cool for a bit.

Spread the ganache evenly over the brownies. Place in the freezer for about an hour.

Use the foil to pull the brownies out of the pan (ignore the misleading picture. USE THE FOIL, or you will have a mess on your hands!!) and place on a cutting board. peel the foil off while the brownies are frozen.

Trim the edges off of the brownies.

Slice into pieces and enjoy!

    Holy cow.
    Way better than my chocolate/peanut butter recipe: Unwrap Ghiradelli dark chocolate square. Insert into peanut butter jar. Scoop up about a teaspoon of peanut butter. Eat. Repeat.

    So last night I thought those were hazelnuts not PEANUT BUTTER CUPS!!
    I am so glad I didn’t know it was peanut butter, Charlie and I would have eaten all of them.

    What brand of chocolate morsels do you use?

    8:44 am on September 23rd, 2011
  31. Heather Christo says:

    Those chocolate morsels are Ghirard- but the price just went up 4$ to 17$ a lb!!! (what a price jump, huh?) So, I am going to switch to Dilletant bulk (a local Seattle Chocolate co.)

  32. Mark Christensen says:

    Heather, am I in love with you or the brownies? Man those look amazing! I think my wife would be mad at me if I made those. But I may have to risk it. ;) My 8 year old son Isaac grabbed a box of Hershey’s brownie mix at the store and made brownies from a box on his own today. I thought for a boy that was a great start. He was very nervous. OH! I almost forgot…. Check out my blog, I have pictures up of the appetizers I made for that networking event. I got a ton of compliments. Oh, and I was only asked to do the food, nothing else.

    Can you check the butter measurment? I made these last night off the Tasty Kitchen website and they turned out awfully greasy. Bon Appetit recipe looks like 1 1/4 sticks of butter not cups of butter. Thanks!

    Pure trouble! But trouble that I would REALLY like to get in to…

    Oh my!

  36. Angie says:

    These are so tasty! Unfortunately, in your recipe you didn’t state when the eggs are added in. I added them before the flour (but after the whole mixture had cooled a bit). Very nice!

    2:51 pm on February 13th, 2012
  37. Angie says:

    Also, I use the heavy duty extra long aluminum foil and so only needed to use one sheet.

    2:53 pm on February 13th, 2012
  38. Heather Christo says:

    thanks Angie, but it says to add eggs one at a time after the butter! Glad they turned out well for you!
