Bloody Halloween Cookies
There’s just something about a themed treat that I love.
I remember last Halloween, seeing a bunch of cool-looking cupcakes and treats made with these little candy knives and bloody axes. So, when I spotted a package of these candy butcher knives at the grocery store, I scooped one up along with some red gel to make my own version of a “Killer” Halloween cookie.
- These Spooky Halloween Cookies are super easy to put together since they are made with a box of Pumpkin Spice Quick Bread Mix, bananas, and a few more ingredients. The addition of a mashed banana gave the cookies an extra little pop of sweetness that really went well with the pumpkin spice flavors.
- The pumpkin cookies are soft on the inside and taste just like a slice of pumpkin bread! They’re good as is, but I added a thick layer of my favorite cream cheese frosting that absolutely put them over the top taste-wise. (Vanilla would be good too if you are not a fan of cream cheese frosting.)

Ingredients in Pumpkin Banana Halloween Cookies
(Ingredients at a glance, grab the full recipe in the printable recipe card below.)
- Pumpkin Spice Quick Bread Mix | 14 to 15 oz box. If you can’t find a quick bread mix you can use a box of yellow cake mix with 1/3 cup pumpkin puree and a tbsp of pumpkin pie spice.
- Butter | Melted
- Egg | large
- Very ripe banana | About one large banana.
- Your favorite frosting | I used cream cheese, but vanilla would be yummy too.
- Red decorator gel
- Candy knives (I found my little meat cleavers at either Walmart or Safeway)
How to make Bloody Knife Halloween Cookies
- Preheat oven to 350. Lightly grease a cookie sheet.
- In a large bowl, stir together bread mix, egg, butter, and banana until everything is combined and a dough forms.
- Scoop a tablespoon size of dough and roll into a ball, place two inches apart on the cookie sheet. Use a spatula to flatten cookie.
- Bake cookies for 10 minutes or until the centers look set. (Don’t overcook the cookies – they will dry out fast.)
- Remove cookies from pan and let cool.
- Thickly frost with your favorite frosting, add red gel to the cookie and place a candy knife in the center.
- Enjoy!
This recipe makes about 24 cookies and works great with just sprinkles too!
The kids loved how the treats looked and my missy even went so far as to make a box and put in two of her cookies to take to her teachers. (My son didn’t want to share and ate all his allotted cookies, lol.)
I regret only buying one box of these candy knives, but we made do with sprinkles for the rest of the cookies. (You just can’t go wrong with icing and sprinkles!)
Recipe Tips:
- Bake cookies for 10 minutes or until the centers look set. (Don’t overcook the cookies – they will dry out fast.) Ovens can vary in their temperature ranges. I recommend setting your timer for 8 minutes and checking to see if they are ready.
- You can use store-bought cream cheese icing or make your own. My foolproof cream cheese icing recipe is:
- 6 oz cream cheese, softened
- 3 tablespoons butter, softened
- 1 1/4 cups powdered sugar
- 1/2 teaspoon vanilla
- Beat frosting ingredients with fork until smooth.
- If baking cookies in batches, don’t place cookie dough onto a hot baking sheet. Be sure to let the baking sheets cool to room temperature first.
How to Store Leftover Cookies
Let the frosting on the cookies set completely before storing. In an airtight container, layer the cookies between sheets of wax paper to prevent them from sticking together.
