Instructions

INSTRUCTIONS FOR THE PUMPKIN BARS:

Preheat the oven to 350 F and line a jelly roll pan with parchment paper.

Add in the flour last and whisk until combined (you can also mix all the dry ingredients separate and then add to the wet ingredients, I prefer to just use one bowl for convenience)

Pour the batter into the parchment-lined jelly roll pan and spread evenly in the pan with a spatula.

    Oh man, moist, perfectly sweetened, delicious pumpkin “cake”! This was a home run recipe in my house. I made this to ring in the fall season and everyone who tried it voted for it to be a dessert on the Thanksgiving table! 10/10.

    Recipe is delicious and soft and tasty. We did increase the sourdough by another 1/4 cup and decreased the oil by 1/4 cup and it came out the same. Soft, moist, delicious and earned a spot in our holiday wish list!
