Peanut M&M Brownies

I’m always in the mood to bake.  Especially when I don’t have to dirty up my stand mixer.  Especially when it’s cloudy and rainy outside.  Especially when I have no plans for the day.  Especially when I already have pie and cupcakes in my kitchen.  Especially when I am craving chocolate.  Especially when… oh, uhm…  well… I guess whenever really!

Remember those peanut M&M in German colors I found a few weeks ago at the Edeka here in Germany?  Well, I haven’t gotten around to using them yet… until today.  But hmm… what should I put them in?  While browsing Pinterest, I came across a pretty simple recipe for brownies from Buns in My Oven which I used as my inspiration for these brownies. Fudgey brownies are my weakness, so I was sure I’d love this recipe!

Just a little note on these brownies, they are super sweet and call for a lot of sugar.  If you want them less sweet, I’d cut the sugar by at least 1/2 a cup… maybe more.  Also, they are really super fudgey, so if you want more cake like brownies, use only 2 eggs.

PS… These would be really good minus the M&Ms and add a cup of peanuts.  The crunch and saltyness of the peanuts go really well in these brownies… I found myself wanting more peanut in each bite!

Peanut M&M Brownies

Yield: 12 brownies
Prep Time: 10 minutes
Cook Time: 30 minutes
Total Time: 40 minutes


  • 1 cup unsalted butter
  • 1 3/4 cups sugar
  • 1/2 cup brown sugar, packed
  • 3/4 cup cocoa powder
  • 1 Tbsp vanilla
  • 2 tsp espresso powder
  • 1 1/2 cups flour
  • 1 tsp baking powder
  • 1 tsp salt
  • 4 eggs
  • 1 cup chocolate chunk
  • 1-2 cups Peanut M&Ms, divided


  1. Preheat oven to 350 F degrees. Butter a 9x13 baking pan. I also lined the bottom with parchment paper.
  2. In a large bowl, whisk together the flour, baking powder and salt. Set aside.
  3. In a medium sauce pan, melt the butter on low-med heat. Whisk in the sugars and cook 1-2 minutes until the sugar has completely dissolved, whisking constantly.
  4. Add the vanilla extract, cocoa powder and espresso powder and whisk until dissolved, about 2 minutes.
  5. Fold the butter/chocolate mixture into the flour mixture until just combined. DO NOT OVER MIX.
  6. Add the eggs and whisk until combined.
  7. Fold in the chocolate chunks & 1 cup of the M&Ms. Use your spatula to scrape the sides and fold a few times to ensure everything is combined.
  8. Spread batter into prepared baking pan.
  9. Use the remaining M&Ms to place on top of the batter. It's always best when you have a few M&Ms showing on top!
  10. Baking 27-33 minutes or until the edges are firm and the center is still a bit soft. Allow to cool in pan before removing to cut and serve.

I just came across this recipe and cut it out of a mag. The recipe calls for 2 cups of vinegar! The instructions have no mention of vinegar. Hope no one makes these brownies according to this recipe.Ly

Yes, I said Peanut M&M's - the guys in my office are APE for the peanut m&ms and so I put them in brownies for them, and they were a hit!
