Ingredient Notes and Substitutions
The base for these Halloween brownies comes together really quickly in one bowl!
- Butter- this recipe uses unsalted melted butter.
- Eggs- this recipe calls for large eggs and they can be either cold or room temperature.
- Cocoa powder- for the darkest, richest brownies, use a high quality dutch process cocoa powder. It can be substituted for regular cocoa powder, but your brownies will not be as rich or as dark.
- Flour- all-purpose flour will make our brownies extra soft and tender.
- Oreos- the edible "dirt" of the dirt and worms. Scrape out the middle filling and just use the chocolate cookie. You can crush them in a plastic bag to get them finely crushed.
- Gummy worms- any brand will work, I do not recommend substituting for sour worms.
Expert Tips
- Always spoon measure your flour when baking-This means using a spoon to fluff the flour first, then spoon it into your measuring cup. This will give the most accurate results when baking without a kitchen scale.
- Cook the pudding until VERY thick- the pudding should be super super thick before taking it off the heat. If it is too thin, it will separate out of the buttercream when mixing.
- Cool the brownies before decorating- frosting the brownies while they're still warm will melt the buttercream.
- Don't over bake the brownies- check the brownies by inserting a tooth pick into the center and pulling it out. It should have just a few crumbs on it and not be completely clean.

Step 8: In a kitchen aid stand mixing bowl, add the soft butter. Using the paddle attachment, beat the butter on medium low for 2 minutes until smooth.
Stop the mixer and add the cooled thick chocolate pudding into the butter 1 tablespoon at a time whipping well after each addition. Do not add more than 1 tablespoon at a time or it will separate from the butter. When all of the pudding has been added, whip the buttercream on high for 2 minutes or until it's light, fluffy, and pale in color.

Decorating
These Halloween brownies are super fun to decorate with the edible "dirt" and gummy worms. They end up tasting exactly like the classic dirt and worms cups you had when you were younger, and if you never had that growing up you are in for such a treat.
Remove the brownies from the baking pan by lifting up the sides of the parchment paper. Use a small offset to loosen the sides if they stick to the pan. Spread the pudding buttercream evenly over the top of the brownies with a spoon or offset spatula.
Scrape the filling from the middle of 3-4 Oreos. Crush the cookies into crumbs and then sprinkle them evenly over the top of the pudding buttercream layer. Cut the brownies into 9 portions and finally top the brownies with gummy worms.
