Peanut Butter Swirl Brownies


The idea for these brownies came from Martha Stewart's Cookies Cookbook. I did not care for the texture of the brownie in that recipe as it was far too cake like, so like flavoristas tend to do, I came up with my own version.

Then I stumbled upon the BEST brownie mix ever – Ghiardelli's Double Chocolate. I like my brownies ooey and almost gooey and this mix delivers. They actually come out as pictured on the box. Lucky for me they sell it in bulk at Costco here in Boulder. I highly recommend that you have this in your pantry as they are quite simply delcicious.


The peanut butter topping does come from the Martha's  book but I adapted it for these brownies. If you like Reese's Peanut Butter Cups, these are for you.

Peanut Butter Swirl    

I haven't tried it yet, but this filling might also be good as a sandwich cookie filling, think homemade nutter butters.

2 Tbsp. butter, melted
1/2 cup smooth peanut butter (I prefer chunky but the kids don't)
1 tsp. vanilla extract
1/8 to 1/4 tsp. salt coarse sea salt
1/4 cup confectioner's sugar


Make the brownies according to the recipe on the box and pour into your prepared brownie pan.

For the peanut butter swirls, place all the ingredients in a small bowl and mix well.

Using a spoon, (or as I prefer a small  1 oz. ice cream scoop), place dollops of the peanut butter just on top of the batter. Using a sharp small knife, place the tip in the center of one of the peanut butter dollops. Now carefully fan the peanut butter out into the batter. Do this on each dollop making longish type swirlies (as pictured above).

Bake for the time as indicated on the brownie box for the pan size you use. I like to use the larger sizes brownie pan as the peanut butter doesn't spread but sets up where it is on the brownie. The brownie batter also tends to rise up around the peanut butter.

It doesn't hurt to sprinkle a few chocolate chips over the top as well.
