These Black Bat Brownies are rich, chocolatey treats with a fun twist! They’re perfect for Halloween or anytime you want a spooky, delicious dessert.
With their dark color and fudgy texture, they make a creepy yet tasty snack. I love serving them with a scoop of ice cream on the side—because why not add a little extra delight? 🍦
Key Ingredients & Substitutions
Unsalted Butter: Fresh butter gives the brownies a rich flavor. If you’re in a pinch, you can use margarine or coconut oil, but the taste may change a bit.
Granulated Sugar: Regular sugar works best, but you can try brown sugar for a slightly different texture and flavor. It makes the brownies a bit chewier!
Cocoa Powder: Unsweetened cocoa is key for that rich chocolate taste. If you don’t have it, Dutch-process cocoa can be a good substitute, but avoid sweetened varieties.
Peanut Butter: Creamy peanut butter is great for drizzling, but if you’re allergic or prefer something different, nut-free alternatives like sunflower seed butter work too!
How Can You Achieve the Perfect Brownie Texture?
Getting that fudgy texture in your brownies can be tricky, but here’s how to master it! The key steps are in the mixing and baking times.
- Mix butter and sugar thoroughly, but don’t over-mix once you add the dry ingredients. This keeps the brownies from being too tough.
- Monitor the baking time closely. Check for doneness with a toothpick; it should come out with a few moist crumbs, not clean.
- Let them cool completely before cutting; this helps them set and creates clean edges.
By following these tips and techniques, your Black Bat Brownies will be a hit at any spooky gathering! Enjoy baking!

Black Bat Brownies
Ingredients You’ll Need:
For the Brownies:
- 1 cup (2 sticks) unsalted butter
- 2 cups granulated sugar
- 4 large eggs
- 1 teaspoon vanilla extract
- 1 cup all-purpose flour
- 1 cup unsweetened cocoa powder
- 1/2 teaspoon salt
- 1/2 teaspoon baking powder
For the Topping:
- 1/2 cup creamy peanut butter (for drizzling)
- 1 cup chocolate ganache or chocolate frosting (can be melted dark chocolate mixed with a little cream)
For the Bat Decorations:
- Black gumdrops or black fondant balls (for bat bodies)
- Black edible wafer paper or black fondant (rolled into thin wings)
- Edible white and black candy eyes
- Edible glitter or sanding sugar (optional, for wings sparkle)
How Much Time Will You Need?
This recipe will take about 15 minutes to prepare and around 25-30 minutes to bake. After baking, you will need to let the brownies cool completely before adding the toppings and decorations, which takes about 30 minutes. In total, plan for about 1 hour and 15 minutes from start to finish!
Step-by-Step Instructions:
1. Preheat the Oven:
Start by preheating your oven to 350°F (175°C). While it heats, grease a 9×9-inch baking pan and line it with parchment paper, leaving some paper hanging over the sides. This will help you easily lift the brownies out later.
2. Make the Brownie Batter:
In a microwave-safe bowl, melt the butter completely. Let it cool slightly. Then, stir in the granulated sugar until everything is well mixed. Add the eggs one at a time, whisking well after each addition. Finally, mix in the vanilla extract.
3. Combine the Dry Ingredients:
In another bowl, sift together the flour, cocoa powder, salt, and baking powder. This will help ensure there are no lumps in your brownies.
4. Mix Wet and Dry Ingredients:
Gradually fold the dry ingredients into the wet mixture until everything is fully combined and smooth. Be careful not to over-mix!
5. Bake the Brownies:
Pour the brownie batter into your prepared baking pan and smooth out the top with a spatula. Bake them in the preheated oven for 25-30 minutes. A toothpick inserted in the center should come out with a few moist crumbs—that’s your cue not to overbake!
6. Cool and Prepare Toppings:
Once baked, let the brownies cool completely in the pan. While they cool, prepare the chocolate ganache or frosting. If you decide to make ganache, gently heat some cream and pour it over chopped chocolate; stir until smooth.
7. Assemble the Brownies:
Spread the chocolate ganache or frosting evenly across the cooled brownies for a delicious layer of chocolate goodness!
8. Add the Peanut Butter Drizzle:
Warm the peanut butter so it’s easy to drizzle. Use a spoon or piping bag to swirl it over the chocolate layer in fun patterns.
9. Decorate with Bats:
Now for the fun part! Roll black gumdrops or fondant into small balls for the bat bodies. Cut the black edible wafer paper or fondant into wing shapes. Optionally, dust them with some edible glitter for a magical touch! Attach candy eyes to each bat body with frosting or edible glue. Insert the wings into the bodies, then place a bat on top of each brownie piece.
10. Serve and Enjoy:
Once your bats are in place, it’s time to slice the brownies into squares and serve! Enjoy these spooky treats at your next Halloween party or anytime you desire a deliciously wicked dessert!

Can I Use a Different Type of Sugar?
Yes! While granulated sugar is recommended for a classic sweetness, you can substitute it with brown sugar for a more caramel-like flavor. Just keep the same amount as the recipe calls for, but keep in mind that it might make the brownies slightly denser.
What Should I Do If My Brownies Are Dry?
If you find your brownies are too dry, it may have been due to overbaking. Be sure to check for doneness at 25 minutes by inserting a toothpick; it should come out with a few moist crumbs. If they do turn out dry, serve with a scoop of ice cream or whipped cream to add moisture!
How Can I Store Leftover Brownies?
To store leftovers, place them in an airtight container at room temperature for up to 3 days. For longer storage, you can refrigerate them for up to a week. Just make sure to let them come to room temperature before serving for the best taste!
Can I Make These Brownies Gluten-Free?
Absolutely! You can substitute the all-purpose flour with a gluten-free flour blend. Make sure the blend is designed to replace regular flour in baking, and your brownies will still turn out delicious!
