Ummm… you’ll have to excuse me for a moment, but I’m currently in the midst of a full-blown “PB Explosion” and it’s utterly distracting. If I seem a little out of sorts, blame these brownies! I might just turn into Marsha or Jan from The Brady Bunch, much like in that famous Snickers commercial. But unlike those characters, it’s not because I’m “hangry.” Oh no. It’s because these brownies are so incredibly, sinfully delicious that I find myself declaring, “I want it NOW,” with all the dramatic urgency of Veruca Salt from Willy Wonka.

It seems I’m quite taken with these crazy characters right now, and honestly, who wouldn’t be? We all have those moments of delightful madness, especially when faced with peanut butter frosted brownies generously loaded with glorious Reese’s Peanut Butter Cups. It’s almost torture to simply look at them without immediately indulging. So, there’s only one logical solution: embrace a little craziness, hum a happy tune, and absolutely devour them! Yes, that’s exactly what you should do.

Essential Ingredients for Your Peanut Butter Brownie Creation

Crafting these sensational Reese’s Peanut Butter Cup Brownies requires a few simple yet essential ingredients that promise a maximum flavor payoff. Here’s what you’ll need to get started:

For the Brownie Base (9×9 inch pan)

  • One Box of Milk or Fudgy Chocolate Brownie Mix: Choose your favorite brand of brownie mix. The beauty of this recipe lies in its simplicity; a quality boxed mix serves as a fantastic foundation. Ensure you have all the additional ingredients specified on your chosen brownie mix package, such as eggs, oil, or water.

For the Irresistible Peanut Butter Buttercream Frosting

  • Unsalted Butter (Room Temperature): Using unsalted butter allows you to control the overall saltiness of the frosting. Bringing it to room temperature is crucial for achieving a smooth, creamy consistency when mixing.
  • Creamy Peanut Butter: Opt for a creamy, classic peanut butter, like Jif or Skippy, for the best results. The smooth texture of these varieties will blend perfectly into the buttercream, providing that signature rich flavor.
  • Confectioners’ Sugar (Powdered Sugar): This fine sugar is essential for creating a light, airy, and smooth frosting without any granular texture.
  • Vanilla Extract: A touch of pure vanilla extract enhances all the other flavors, adding warmth and depth to the peanut butter buttercream.
  • Salt: Just a pinch of salt is vital for balancing the sweetness of the frosting and truly bringing out the rich peanut butter flavor.
  • Milk of Choice: You’ll need a few tablespoons of milk to adjust the frosting to your desired consistency. Whole milk often yields the richest frosting, but any milk you have on hand will work.
  • Mini Reese’s Peanut Butter Cups (or Chopped Larger Cups): These are the stars of the show! Mini cups can be used whole, or if you prefer larger cups, simply chop them into bite-sized pieces. They provide incredible texture and concentrated bursts of peanut butter and chocolate flavor.

Crafting Your Peanut Butter Frosted Brownies with Peanut Butter Cups!

Creating these sensational brownies is a straightforward process that yields incredibly delicious results. Follow these simple steps for a dessert that’s sure to impress:

Step-by-Step for the Brownie Base

  1. Prepare Your Brownie Mix: Begin by preparing your chosen brownie mix according to the package instructions. Make sure to use a 9×9 inch baking pan to achieve the perfect thickness for your brownies. Once mixed, bake the brownies as directed on the box.
  2. Cool Completely: This is a crucial step! After baking, allow the brownies to cool completely on a wire rack before attempting to frost them. Rushing this step will cause your beautiful peanut butter buttercream to melt and slide off, creating a messy, rather than magnificent, dessert.

Step-by-Step for the Peanut Butter Buttercream Frosting

  1. Cream Butter and Peanut Butter: In a large mixing bowl, using an electric mixer, cream together the room temperature unsalted butter and creamy peanut butter for 1-2 minutes. Mix until the mixture is light, fluffy, and well combined. This ensures a smooth base for your frosting.
  2. Add Vanilla and Salt: Incorporate the vanilla extract and salt into the butter-peanut butter mixture. Beat for another minute to thoroughly combine these flavor enhancers.
  3. Gradually Add Confectioners’ Sugar: With the mixer on low speed, gradually add the confectioners’ sugar, one cup at a time, until it is fully incorporated. Continue beating until the frosting is smooth and lump-free.
  4. Achieve Perfect Consistency with Milk: Slowly add 2 to 3 tablespoons of your milk of choice, one tablespoon at a time, beating after each addition. Continue until the frosting reaches your desired creamy and spreadable consistency. If it’s too thick, add a tiny bit more milk; if it’s too thin, a spoonful of extra confectioners’ sugar can help.
  5. Frost Your Brownies: Once your brownies are completely cool and your frosting is perfectly smooth, generously spread the peanut butter buttercream over the entire surface of the brownies. Use an offset spatula or the back of a spoon to create attractive swirls.
  6. Adorn with Reese’s Cups: Finally, scatter the mini Reese’s Peanut Butter Cups, or your chopped larger cups, generously over the frosted brownies. Press them gently into the frosting to secure them.
  7. Enjoy Your Masterpiece: Slice, serve, and savor every indulgent bite! These brownies are best enjoyed fresh, but leftovers (if there are any!) can be stored in an airtight container at room temperature for a few days, or refrigerated for longer freshness.
