reeses-chocolate-peanut-butter-cup-explosion-cookie-bars Have I told you guys how often it is that I genuinely forget there’s anyone reading my blog? I mean, I still know that you read it but at the same time my mind can never seem to wrap itself around the concept that someone is interested in anything I’ve written. But the moment I let my self completely forget, that’s when one of you will drop me the sweetest email or leave the kindest comments to remind me and it usually turns my whole day around. Words are powerful things, man.

reeses-chocolate-peanut-butter-cup-explosion-cookie-bars-2 Okay, so I have to ask, do you think it’s possible to have too much peanut butter and/or chocolate? Because um……there is a little bit of it in these bars and I’m just not seeing how it’s a problem. Fine, so obviously too much of any on thing is not good but what I’m talking about is all of the different forms of those two epic ingredients that are incorporated into these bars.

I feel like there’s been a lot between thesethese, these, and these, and even this cake was optional as a way to use peanut butter. But like I said; can you have too much? Something about the month of September makes me crave peanut butter more so than even the rest of the year. However, I think my recent obsession with it has also been partly due to how oblivious the culture here seems to be about its creamy goodness.

reeses-chocolate-peanut-butter-cup-explosion-cookie-bars-3 It’s not really that Chileans don’t like peanut butter, it’s just that most of them don’t know if they like it because peanut butter is not a common thing here. You’d think by now I’d have realized that I’ll never be able to single-handedly shift the way a whole country eats, but clearly I haven’t given up hope yet ’cause I keep trying anyway.

reeses-chocolate-peanut-butter-cup-explosion-cookie-bars-5 So I’m going to be honest with you, these are not for the faint of heart. I’m talking, serious peanut butter and chocolate heart-attack material here and yet they’re so irresistible. Indulge at your own risk. The name sort of says it all I think, dangerous. I’m almost wondering if I should feel guilty about sharing them. On the flip side, it’s pretty hard to rule them out as completely unhealthy because being happy is a huge part of being healthy and these are guaranteed to make people very happy with every decadent bite. See, so that makes them partly healthy right? Do you see where I’m going with this logic?

reeses-chocolate-peanut-butter-cup-explosion-cookie-bars-6  Haha, okay so maybe we won’t go that far. I’m clearly trying to ease my conscience with things that don’t even make sense. Since we’re all friends here I won’t do any more sugar-coating the fact that these already have too much sugar. Sometimes you just have to live a little, you know? This is one of those times and that’s what these bars are, an experience. An explosive, peanut butter loaded, chocolate stuffed experience. Just do it!


Reese’s Chocolate Peanut Butter Explosion Cookie Bars

Prep Time: 15 minutes

Cook Time: 30 minutes

Total Time: 45 minutes

Yield: 16 servings


    Chocolate Cookie Dough:
  • 1/2 cup (1 stick) butter, softened
  • 1 cup sugar
  • 1 egg
  • 1/2 teaspoon salt
  • 1/2 teaspoon baking soda
  • 1 teaspoon vanilla
  • 1/4 cup cocoa powder
  • 1 2/3 cup flour
  • 1/2 cup semi-sweet chocolate chips or chopped chocolate
  • 1/2 cup chopped reese's peanut butter cups
  • Peanut Butter Filling:
  • 1/3 cup creamy peanut butter
  • 1/4 cup butter, melted
  • 2 1/4 cups powdered sugar
  • 2 teaspoons milk
  • 1/2 teaspoon salt
  • 1 teaspoon vanilla extract
  • Peanut Butter Drizzle:(Optional)
  • 1 tablespoon creamy peanut butter
  • 1/2 cup powdered sugar
  • 1 tablespoon milk
  • 1/8 teaspoon salt
  • 1/2 teaspoon vanilla extract


  1. Preheat the oven to 350 (180C) and grease an 8x8 or 7x11 inch pan with oil.
  2. Chocolate Cookie Dough:
  3. Cream together the butter and sugar in the bowl of stand mixer or a medium mixing bowl. Add the egg and beat until combined then add salt, soda, and vanilla and mix well. Now stir in the cocoa on low until mixed, then add the flour last and continue stirring until your dough comes together. Fold in the chocolate chips and reese's with a large spatula and divide the dough in half.
  4. Spread half of the dough in the bottom of prepared pan (the dough may be a bit sticky to work with so if you are having trouble it can be chilled until easier to handle.) and press into a smooth layer.
  5. Peanut Butter Filling:
  6. Stir together the melted butter and peanut butter in another medium bowl until smooth. Add the salt, vanilla, and milk and mix until combined then add the powdered sugar a little at a time and mix to incorporate into a thick dough.
  7. Scrape the filling mixture out onto the base cookie dough layer and also press it down to form an even peanut butter layer on top of the chocolate dough.
  8. Now scrape out the remaining chocolate dough over the filling layer and crumble evenly over it for the top layer.
  9. Bake the bars for 18 to 22 minutes until the top is starting to darken and brown on the edges. Remove from oven and, if desired, immediately sprinkle some additional chopped reese's over top and press down very gently. Allow the bars to cool completely before cutting.
  10. Drizzle:
  11. If you'd like to add the extra drizzle, whisk together the ingredients in a small bowl until smooth and use a small tipped pastry bag or simply a fork to drizzle over bars.

    These look insanely good!! But I’ll have to save the recipe for a weekend and invite some friends over – I wouldn’t be able to resist having a peace every day if I had these in my pantry…
