Fudgy Chocolate Brownies with a natural peanut butter swirl. I used to think making brownies from scratch was hard, until I created this recipe. Easy and quick. Great for week night desserts. My kids were a huge fan of these! Bring them to your neighborhood pot luck and make sure to bring the recipe.

I made a half recipe as a test and baked it in a small loaf pan (8.5 x 4.5 inches) for about 14 minutes. The sweetness was perfect for me (it is an "adult" sweetness that I prefer). This recipe produces a cakelike brownie and I prefer fudgy, so next time I would omit the baking powder, use less flour and I'd also increase the peanut butter for the swirl. This is a much easier recipe than those swirl recipes that make you prepare two separate batters that you then swirl together in the pan. Thanks for posting this ... it's a keeper for me!

Really liked this recipe. I liked the mixture of brown & white sugars--something you don't see w/ a lot of brownie recipes! I don't think I did as well w/ the "swirl" but I hope to do better in the future! I used a 9X9 pan & it took 16 minutes to cook. Thanks so much for sharing!!

I cut the sugar back a bit and added closer to a 1/2 cup of cocoa powder. I used 1/3 cup coconut flour to make it gluten free. I also added more peanut butter, melted in the microwave, to make it easy to drizzle on. Really delicious.
