Pumpkin Sheet Cake with Brown Butter Frosting

To Make the Cake:

1. Preheat the oven to 350 degrees F. Grease a 9x13-inch cake pan with cooking spray and line with a sheet of parchment (this makes it easier to remove it from the pan) and set aside. Alternatively you can make cupcakes and cake pans
2. In the a medium bowl, whisk together the flour, sugar, baking powder, pumpkin pie spice, baking soda and salt.
3. In the bowl of a stand-up mixer (or a large bowl using an electric mixer), whisk together the eggs, neutral oil, pumpkin puree and vanilla extract until smooth.
4. Add the dry ingredients and mix until just combined. Pour the batter into the pan and smooth it out using an offset spatula or butter knife. Transfer to the oven to bake for 25 to 30 minutes, or until a skewer comes out clean. Allow to cool in the pan for about 10 minutes and then invert it onto a cooling rack. BE CAREFUL IT'S A BIG CAKE.

To Make the Brown Butter Frosting:

1. If you’ll notice in the recipe it calls for the butter to be divided so! Two sticks (1 cup) are going to be room temperature. One stick (1/2 cup) of the butter is what we’re going to brown.
2. Go ahead and start by adding the room temperature butter to the bowl of a stand-up mixer with the paddle attachment (OR a medium bowl using an electric mixer).
3. Cube up 1/2 cup of the butter (1 stick). In a small saucepan, set over medium heat, add the cubed butter. Once it’s melted, it will begin to foam up and bubble a bit. Allow it to cook until you begin to see lightly browned specks beginning to form. Give it a stir and cook until it’s browned. You should also start to smell its nutty aroma. Remove it from the pan and continue to stir to cool it down.
4. Transfer it to a small bowl (freezer-safe) and place it in the freezer to chill, for about 10 to 15 minutes. We want it to be around room temperature butter. After it gets to that room temperature butter-firmness (it can be a bit softer—that’s ok), transfer it to the bowl with the other room temperature butter.
5. Sift in the powdered sugar and add the vanilla extract, salt and heavy cream. Beat the frosting for about 3 minutes. The fluffiness from the heavy cream really lightens up this frosting so be sure to beat it for the full 3 minutes.

To Assemble the Cake:

1. Pour all of the frosting on the cooled sheet cake and spread it around, creating cute swoops as you go. Top it with some sprinkles and cut it up and slice! Cake will stay moist for about 3 days when wrapped properly.
