The Best Pattypan Squash Brownies Recipe with Frosting

Pattypan Squash Brownies

Delicious Patty Pan Squash Brownies Recipe with Frosting

This is one of my favorite brownie recipes. My kids love these brownies, I don’t think they even know there is pattypan squash in the brownies, or maybe they just don’t care because the brownies are that good!

The recipe uses two cups of shredded pattypan squash and is a great way to use up some of that summer bounty.

If you aren’t familiar with pattypan squash it looks like a flying saucer. If you are using a different variety of squash or zucchini, you should squeeze out the excess moisture.

I used a Kitchen Aid shredding attachment to shred the squash because I’m lazy like that. I cut the squash into four pieces (from the top) scooped out the seeds and then feed the squash into the kitchen aid shredding attachment skins and all.

I used natural applesauce instead of oil. The batter was just moist enough and the brownies turned out delicious! Glad I had extra patty pans to shred and freeze. I will be making these often

Something missing from this recipe. I added two eggs cause batter was way too thick. Not enough liquid to wet all ingredients. Hoping it comes out ok.

I just made these brownies. The batter was very dry when it was all combined. I added water (1/4 cup) until the batter moistened a bit. Spread and patted into the pan. Honestly, I didn't expect much. I've never had a batter like that for any of my baking. 20 minutes later...delicious brownies! I am shocked and pleasantly surprised. I find them sweet enough without the frosting. This recipe really does work! It was so quick to toss together. It gives me a reason to plant patty pans again next year. My go to Patty Pan Brownie recipe. Thanks so much for posting!
