IT IS PUMPKIN WEEK here at RMK! I must say this has got to be one of my top theme weeks that I look forward to each year. I love fall and pumpkin week always tells me that fall is here. Now, I have some delicious pumpkin recipes lined up like these 3 Ingredient Pumpkin Brownies. I’m even including a flashback recipe that is one of my favorite pumpkin recipes for you.

To start off, we are beginning with an easy one. This recipe makes brownies using 3 ingredients – a brownie mix, some cinnamon, and a can of pumpkin. You mix those 3 things together and bake for 25 minutes at 350 degrees. It’s baking in a 9 x 9 inch pan. This results in a dense fudgy brownie!

Then, they get taken up a notch further by topping them with a simple buttercream recipe with cinnamon. This is added to it to highlight that warm cinnamon spice that pairs perfectly with pumpkin. The frosting is made by beating some butter and powdered sugar together along with some cinnamon, vanilla, and a little milk.

Three shouts for these 3 ingredient pumpkin brownies and three shouts for pumpkin week. I hope you enjoy all of the recipes!

  1. Me again. I tried this recipe and couldn’t believe how rich and decadent the brownies are, especially for such an easy recipe. This is definitely a keeper. Thank you!

  2. This sounds so good but I just want to be clear. We put the dry brownie mix in straight from the box…we don’t add the eggs or whatever we would if we were making up the mix as regular brownies?
