    Gluten Free Halloween Mummy Brownies

    Need this to be gluten-free, and looking for a delicious homemade brownie recipe?

    Try my Easy Gluten Free Brownies - it’s my favorite brownie recipe.

    That recipe - like the one used to make these spooky Halloween brownies - also turns out thick, decadent, fudgy brownies. You’d never know they were gluten free!

    They’re perfect as an inclusive treat when some of the little Monsters you’ll be hosting at your Halloween party are celiac or gluten intolerant!

    Once you make and cool that batch of chocolate brownies, come back here and continue with the frosting recipe (naturally gluten free), and decoration tutorial.

    Just be sure that the candy eyes you use are gluten free, and you’ll have fun Halloween treats for everyone!

    Ingredients and Equipment

    If you do any baking normally, you’re likely to have almost everything you need to make this delicious recipe, on hand!

    Ingredients

    This recipe uses super basic ingredients that you’re sure to find in any grocery store.

    Chewy Brownies

    Dark Brown Sugar
    Granulated Sugar
    All purpose flour
    Cocoa powder
    Baking Powder
    Salt
    Butter
    Large Eggs
    Pure vanilla extract

    If you want black cupcakes, you can add a bit of Black Gel Food Coloring with the wet ingredients, I usually don’t bother.

    Decoration

    Butter
    Pure vanilla Extract
    Salt
    2 cups Confectioners sugar / Icing sugar / Powdered sugar
    Milk
    Candy Eyeballs

    A hand holds a pastry bag fit with a coupler and flat tip.

    Equipment

    If you’re reasonably able bodied, you can make these delicious brownies with just a bowl and a wooden spoon and a bowl, no need for an electric mixer or stand mixer (at least until you make the frosting, anyway!).

    No shame in using a mixer, though. I just can’t be arsed to wash the beaters, if a spoon is an option!

    Aside from that, you’ll want a 9 x 13 pan. I like to use a nonstick cake pan (Lined with parchment), as I like the straighter sides and the texture it gives my brownies.

    That said, many people swear by glass pans for brownies. Glass takes longer to heat up, which means a longer baking time... but it also means it’s not as prone to overcooking.

    When it comes to making the perfect brownies, the big thing is to not overbake them. If it’s your first time making this - or any - brownie recipe, I recommend testing it for doneness 5 minutes early, just in case.

    Overcooked brownies will still TASTE good, but they’ll be dry.


    Decorating Equipment

    As for decorating, you’ll want a Piping Bag fit with a Decorating Coupler and a narrow Basketweave Tip.

    Wilton has a few that would work well, it's just a matter of your taste.

    I like their #46 or #47 , but you can use anything from 44-48.

    How to Make Fun Halloween Brownies

    The full recipe follows in the recipe card at the end of this post, this is a pictorial walk through.

    Homemade Brownies

    Preheat oven to 350°. Prepare 9 x 13 inch pan with pan spray or shortening, line with parchment paper.

    A 9 x 13 baking pan lined with parchment paper.

    In large bowl, combine all of the dry ingredients. Set aside.

    In a smaller bowl, whisk together melted butter, eggs, and vanilla extract.

    Add wet ingredients mixture to the flour mixture, stir until dry ingredients are well incorporated.

    Use a rubber spatula to spread batter into prepared pan, Bake for 30 min in the center of the oven.

    Brownies are done when knife inserted into center of the brownies comes out just barely clean - but don’t OVER cook them.

    Let cool completely to room temperature before proceeding.

    Frosting

    In a small bowl, whip butter until smooth. Add Vanilla and salt, mix until well incorporated.

    Slowly add the powdered sugar a little bit at a time, until incorporated completely.

    Beat on high for 1 minute - mixture will be very, very thick and probably crumbly. Lower mixer speed to lowest setting, and slowly add ½ of the milk. Beat until smooth.

    Add remaining powdered sugar and remaining milk - alternating - and continue to beat until smooth.

    Once incorporated, check for consistency. Add more milk or sugar to achieve the consistency you want or need.

    Decorating

    If you’d like, you can use a bit of White Gel Food Coloring to whiten the frosting a bit - the butter and vanilla tend to make it off-white.

    Which is fine when we’re talking about mummies, really. Pristine white gauze after thousands of years in a tomb? I don’t think so.

    Anyway.

    Fit a large piping bag with a coupler and a flat tip, fill with frosting. Make sure to avoid air pockets as much as possible.

    Use the parchment paper to carefully lift the slab of brownie out of the pan. Be careful to support it and not allow it to bend / break as your transfer it to a flat cutting surface.

    Use a sharp knife to cut the brownie slab into 12 rectangular pieces - 3 x 4.

    Use the flat side of the piping tip to pipe strips of icing across the top of the brownies at random angles, as shown.

    Pipe a couple dots to act as glue, and secure a couple Candy Eyes in place.

    Brownies can be stored in an airtight container for several days, if needed.

    Halloween Brownie Variations

    Dairy Free Halloween Brownies

    Need dairy-free brownies? Swap out the butter for your favorite plant based alternative (Vegetable oil works in the brownie itself).

    White Chocolate Mummies

    For a variation on the frosting, melt ½ cup white chocolate chips, and allow to cool slightly.

    Beat melted chocolate into the frosting, tint whiter if desired.

    The Easy Way

    Prefer to use a box mix?

    You can make the same basic idea of these with a boxed brownie mix and canned frosting. If you do this, follow the directions on your boxed mix to make the actual brownies.

    Also: Be sure to check the box of brownie mix that you use. If it’s not a 9 x 13 pan used, you’ll want to adjust the cutting however you need to, in order to get nice rectangles.
