Peanut Butter Swirl Brownies

Peanut butter and chocolate are always a delicious duo, but they're extra-special paired in this tempting treat. Even with a sizable collection of brownie recipes, I reach for this one quite often. The marbled look attracts curious tasters...the flavor brings them back for seconds. - Linda Craig, Hay River, Northwest Territories

    These brownies were soooo yummy. I didn't separate half the mix..I just put all ingredients in the bowl and mixed...i did throw extra chips in there and microwaved about a 1/3 c. of peanut butter..dropped about 12 tbls. on top...took knife and swirled MORE PB on it and put in 13x9 pan (little thinner but soooo good)...only 22 mins.

    For some reason, my brownies came out more of a cake texture rather than the "brownie" texture but peanut butter is my favorite, so I'll probably make it again

    So good! I prefer the pb layer, so I divide the batter not so evenly. I've made these several times. Always a hit.

    These are easy to make & taste fantastic! My only complaint is that mine sunk in the middle - a common occurrence when baking brownies at a high altitude. If I make again, I will make some adjustments & try to fix that.
