How to Make the Fudgy Brownie Base
Let's go over what ingredients you'll need to make these pumpkin frosted brownies and the basic steps for making them. For the detailed recipe, including the pumpkin buttercream frosting recipe, scroll down.
Ingredients needed. All-purpose flour, salt, baking powder, unsweetened cocoa powder, vegetable shortening, granulated sugar, dark chocolate, eggs, water, and semi-sweet chocolate chips.
Whisk the dry ingredients together. I know some skip this step, but it really is an easy one that helps to blend all the dry ingredients together before you add them to the rest of the batter.
Melt the chocolate. I prefer to melt it in the microwave in a heat-proof bowl or measuring cup. Heat it for 45 seconds to 1 minute, full powder, stirring in between.
Blend the shortening and sugar together. Get it to that light and fluffy-looking consistency. And yes, you can substitute the shortening for unsalted butter. I did not test this recipe using any oil.
Add the remaining ingredients. This includes eggs, melted chocolate, vanilla extract, water, and chocolate chips. The chocolate chips are optional and should be folded in with a spatula. Mix together until just combined. Do not over-mix the batter.
Bake the brownies. 25-28 minutes at 350ºF. Brownies will be done when an inserted toothpick comes out with just brownie crumbs. Not wet batter. Be careful not to over back them.
Let them cool completely. Brownies will continue to bake as they cool down. Cooled brownies are easier to cut, and the pumpkin frosting won't melt, either.

Tips for Making Pumpkin Buttercream Frosting
Use room-temperature butter. It should be soft enough to leave an imprint without applying too much pressure. The butter shouldn't be so soft that it's almost melting as you unwrap it. This helps blend it well with the pumpkin puree, spices, and powdered sugar.
Store leftover pumpkin puree in the refrigerator. You won't use all of the pumpkin puree from the 15-ounce can. Place any leftovers in the refrigerator to use with my pumpkin pie, pumpkin cinnamon cookies, one bowl chocolate chip pumpkin bread, or chocolate pumpkin cake roll recipes!
Sift the powdered sugar. An important tip that will keep any stubborn lumps out of your beautiful looking—and tasting— pumpkin frosting! I don't recommend skipping this.
Double the recipe (for frosting lovers). If you like a thicker layer of frosting on top of your brownies, then I recommend doubling this recipe.

Hi! I'd love to try this recipe but we don't get shortening where I live. Can it work with oil?
Jennifer says
Hi Jade! I haven't made them using oil, but you can use butter as a substitute. It would be the same measurement as the shortening.
