Yesterday was Sweetest Day – do you celebrate/acknowledge it? I think I read once that it’s a Hallmark holiday only celebrated in the Midwest. So maybe you’ve never even heard of it. It’s something like Valentine’s Day.

Yesterday we also celebrated one of my bestie’s 30th birthday. She asked me to make her a birthday treat, which I was happy to do.

I wasn’t sure what to make but then I remembered I could stalk her Pinterest boards and see what she had her eye on.

Ah, the ease of stalking with social media.


Below is a list of the ingredients you’ll need to gather to make this recipe. Scroll all the way down for the full recipe card.

  • Brownie Mix – Use your favorite brownie mix (I like Ghirardelli Double Chocolate, if I had to pick) or make brownie batter from scratch.
  • Peanut Butter Chips – These should be easy to find in the chocolate chip section of the market.
  • Mini Chocolate Chips – Semi-sweet or whatever your favorite are.
  • Creamy Peanut Butter – I usually use Skippy Natural.

How to make Mini Brownies

Baking brownies in a mini muffin pan makes making mini brownies really easy.

First, remember to spray the mini muffin pan with non-stick spray before you start so they’ll pop out easily.

Mix up your favorite brownie mix according to the package instructions, or make them from scratch, then evenly distribute the batter amongst the 24 wells (use a mini cookie scoop to make it easy!).

Bake for 13-15 minutes at 350 degrees or until the centers are set. 

Once the brownie bites come out of the oven, gently indent each brownie with the back of a teaspoon or your thumb (they don’t have to be pretty, you’re going to fill them with peanut butter) to make a well for the peanut butter sauce. 

Put the peanut butter in a microwave safe bowl and heat for 45 seconds then give it a stir. The peanut butter should be thin & runny. 

Spoon about a teaspoon of the melty peanut butter into each brownie and sprinkle with mini chocolate chips and peanut butter chips.

Serve & enjoy!

How long to cook brownie bites

Baking Chocolate Peanut Butter Brownie Bites only takes 13-15 minutes at 350 degrees.

I’ve been on quite the brownie and chocolate and peanut butter kick lately. It’s counterproductive to my gym efforts but oh so good. I need to start making some dinners, preferably some healthy ones.

I planned on making the brownie portion of these from scratch but I ran short on time (read: I spent too much time wandering around ULTA) so I used a Ghirardelli Double Chocolate box mix.

Using the mix makes it a very quick recipe that looks pretty impressive and tastes really good.
