Haunted Halloween Brownie Brittle is the perfect crispy, chocolatey treat to delight your family and friends on October 31st and through the Halloween season.
Preheat the oven to 325°. Completely line a large rimmed baking sheet (18×13 works well, if you don't have that size use two smaller pans) with a piece of parchment paper.Do not skip this step! The recipe will not work without the parchment paper. The brittle will be ONTO the pan without it!
In a microwave safe bowl melt together the butter, vegetable oil, and the bittersweet chocolate squares, for about 30 seconds. Give it a good stir to make sure the chocolate is completely melted.
Stir all the cocoa powder into the melted chocolate mixture. Set aside.
In a stand mixer fitted with the whisk attachment (or handheld mixer), whisk the egg whites, on medium-high speed, until they are really frothy, about 4 minutes. Add the vanilla extract and sugar to the egg whites and whisk another 15 seconds.
Pour the melted chocolate mixture into the egg white mixture and mix for another 20-30 seconds.
In a separate bowl stir together the flour, baking soda and salt.
Pour the flour mixture into the batter and fold it in with a spatula or wooden spoon until it is combined.
Pour the batter onto the parchment paper lined baking sheet. Using a spatula spread the batter across the parchment paper until it is really, really thin, about ¼ inch thick at most. It will be like you are painting the batter on the parchment paper!
Make sure you get the batter spread thin enough so it bakes crispy!
Sprinkle the mini chocolate chips across the batter.
Bake for 10 minutes.Remove from the oven and working quickly sprinkle on all your edible Halloween decorations (candy corn, sprinkles, eyeballs, etc...) giving them a light press with a spatula to make sure they stick.
Place the pan back in the oven for another 5-8 minutes. If the edges aren't browning at 5 minutes continue baking until the 8 minute mark.
As soon as the brittle comes out the oven it will still be soft, score it with a knife or pizza cutter (into shapes that you want the individual pieces to be).
Then let it cool for about 15-20 minutes to dry and get crispy.
Break it apart into bite sized pieces.
Enjoy your Haunted Halloween Brownie Brittle!!
Storing
Keep your brownie brittle in an airtight container at room temp for up to a week.
Notes
Rimmed Baking Sheet - You will want to use an 18x13 rimmed baking sheet to make your Haunted Halloween Brownie Brittle. If you do not have that size, you can use two smaller baking sheets and divide the batter between the two pans.
