Giant Halloween Pumpkin Cookies and Roasted Seeds Recipes

Updated October 2019

Many of us are trying to be more eco-friendly and head towards zero waste, so why not use the whole pumpkin when you’re preparing for Trick or Treat. This recipe for giant Halloween pumpkin cookies will use up all the leftover flesh from your Halloween pumpkin carvings, and I will tell you how to make roasted pumpkin seeds too. They are really yummy and so healthy for you which will, of course, balance out all the cake!

I found an American recipe for these giant Halloween pumpkin cookies last year but it was all in cup sizes. Rather than mess about trying to convert, I found that you could buy the measuring cups very cheaply in large supermarkets.

Giant Halloween Pumpkin Cookie Recipe


1 cup  plain flour (gluten free is fine)
2/3 cup porridge oats
1 teaspoon ground cinnamon
1/2 teaspoon baking soda
1/2 teaspoon table salt
1/4 teaspoon ground mixed spice
3/4 cup  sugar, plus additional for sprinkling
1/2 cup pumpkin puree
1/3 cup vegetable oil
1 tablespoon honey or syrup
1 teaspoon vanilla extract
1/2 cup raisins/sultanas


1. Preheat oven to 180 degrees
2. Stir together the flour, oats, cinnamon, baking soda, salt and spice in a medium-sized bowl.
3. In a separate large bowl, combine the sugar, pumpkin puree, oil, syrup and vanilla; whisk to blend.
4. Stir the dry ingredients into the pumpkin mixture then stir in the raisins (optional).
5. For each cookie, drop 1 generous tablespoon of batter onto the prepared baking sheet, spacing the mounds about 1 inch apart.
6. Bake the cookies until brown and a bit firm to the touch, 17 to 20 minutes. Place on a rack to cool.

How to Make Roasted Pumpkin Seeds

Pumpkins are so cheap this year but rather than waste all the insides why not make some tasty treats and healthy snacks with the seeds.

1. Scoop out all the pumpkin inners.
2. Separate the seeds from the pith.
3. Spray a baking tray with a little spray olive oil
3. Spread the seeds out on a baking tray, sprinkle with a little salt and pepper if desired,  and roast at the same time as you make the cookies.
4. Roast the pumpkin seeds from 10 minutes to half an hour depending on how crispy you like them.

Roasted pumpkin seeds really are a delicious healthy snack.

  1. Do you know the best way to measure 1/3 cup please? My cups are spoons and I only have 1, 1/2, 1/4 and 1/8 so I have to use guesswork for thirds!

  2. This is a great idea! I’m not the best at pumpkin carving, but wondered what is the best tool to scoop out pumpkin flesh? I was using a spoon and it was quite difficult!

    • I use a big tablespoon to scoop out the pithy bits with the seeds in, then pick out the seeds with your hands.

      The flesh can be very tough so it’s easier to cut the pumpkin up into 1/4 or 1/8 with a large sharp knife, then peel the skin off like you would a melon. Depending on what recipe you are using, chop the pieces up and put through a grater in a food processor. Then puree if necessary.


  3. Loving all these recipe posts. Currently going through some hellish tummy symptoms and may actually be intolerant to certain foods I’ve been gorging on for years that I thought were healthy – including pumpkin and sunflower seeds! Gutted!
