Can I make these mummy cookies gluten-free?

Yes, absolutely. Simply use oat flour that is certified gluten-free. Oats themselves do not contain gluten but are often processed in facilities that handle wheat, so the certification matters if you are catering for someone with coeliac disease or a gluten sensitivity.

How do I make these healthy Halloween mummy cookies dairy-free?

Swap the Greek yogurt for a thick coconut yogurt in the drizzle and use any plant-based milk such as oat or almond in the dough. The end result is just as creamy and the mummy decoration looks identical.

Can I use a different flour instead of oat flour?

You can try almond flour for a lower-carb version, though the texture will be slightly softer and more fragile. Buckwheat flour also works well and adds an earthy flavour. Plain white flour is not recommended as it defeats the healthier purpose of the recipe.

How long do these mummy cookies stay fresh?

Once decorated, these cookies keep well in an airtight container in the refrigerator for up to 3 days. The yogurt drizzle stays set and the cookies retain their soft texture throughout.

Can children help make these cookies?

This is one of the best baking projects to do with kids. Little hands are great at mashing the banana, shaping the dough into oval mummy bodies and pressing the chocolate chip eyes into place. The piping bag might need adult supervision, but the whole process is fun and low-stress.

Are these cookies suitable for people watching their sugar intake?

Yes. Each cookie contains only about 5 grams of sugar, coming from coconut sugar, banana and a small amount of honey in the drizzle. That is significantly lower than traditional mummy cookies made with refined icing sugar coatings, which can contain 12 to 15 grams of sugar per cookie.

Mummy Cookies Healthy Halloween Treats with Oat Flour and Greek Yogurt Drizzle

Halloween baking does not have to mean a sugar crash before the trick-or-treaters even knock. These healthy Halloween mummy cookies bring all the spooky charm of the classic treat without the usual mountain of refined sugar and white flour. Made with wholesome oat flour, a touch of coconut sugar and real cocoa powder, they are the kind of cookie you can feel genuinely good about handing to kids and sneaking one yourself after bedtime. If you have been searching for mummy cookies healthy Halloween recipes that actually taste amazing, this is the one to bookmark.

The base of these cookies relies on fine oat flour, which brings a naturally mild, slightly nutty flavour and a fantastic boost of soluble fibre compared to plain white flour. Coconut sugar replaces refined white sugar, giving a gentle caramel warmth while landing lower on the glycaemic index. A ripe mashed banana adds natural sweetness and moisture so you can cut back on added fats without sacrificing that soft, chewy bite. Raw cacao powder delivers deep chocolate flavour along with genuine antioxidant benefits. For the mummy wrapping effect, a simple drizzle made from thick Greek yogurt and a tiny squeeze of honey sets into a beautifully white, creamy finish once chilled. Two chocolate chips pressed in for eyes finish the look perfectly and the whole thing comes together in under 40 minutes.

Texture-wise, these cookies sit somewhere between a soft fudge cookie and a brownie bite. They are dense in the best possible way, with a tender crumb that holds together well for little hands. The yogurt drizzle adds a subtle tang that cuts through the richness of the cocoa, creating a genuinely balanced flavour. Serve them on a dark plate lined with orange parchment for full Halloween drama, or stack them in a clear bag tied with black ribbon for a crowd-pleasing party favour. They also pair wonderfully with a small glass of oat milk or a warm mug of herbal tea for the grown-ups at the table.

From a nutritional standpoint, each cookie comes in at around 95 calories with over 2 grams of fibre and a notable protein contribution from the Greek yogurt drizzle and oat base. Compared to a traditional mummy cookie made with butter, white flour and powdered sugar coating, you are looking at roughly 40 percent fewer calories per serve and significantly less sugar. They are naturally gluten-free as long as you use certified gluten-free oat flour, and the recipe is easily adapted to be fully dairy-free by swapping the Greek yogurt for a thick coconut yogurt. No artificial colours, no preservatives and no ingredients you cannot pronounce. Spooky on the outside, nourishing on the inside. That is the spirit of healthy Halloween baking done right.

Ingredients

Serves:18

1.5 cups fine oat flour (certified gluten-free if needed)
3 tbsp raw cacao powder (or unsweetened cocoa powder)
1 tsp baking powder
0.3 tsp fine sea salt
0.5 tsp ground cinnamon
1 large ripe banana (well mashed, about 100g)
3 tbsp coconut sugar
3 tbsp coconut oil (melted and cooled)
1 large egg (room temperature)
1 tsp vanilla extract
2 tbsp unsweetened almond milk (or any milk of choice)
0.5 cup thick full-fat Greek yogurt (or thick coconut yogurt for dairy-free)
1 tsp raw honey (or maple syrup for vegan)
36 pieces dark chocolate chips (2 per cookie for the eyes, 70 percent cocoa minimum)

Instructions

1
Preheat your oven to 175 degrees Celsius (350 degrees Fahrenheit). Line a large baking sheet with parchment paper and set aside.
Make sure your oven is fully preheated before the cookies go in. This helps them set with the right texture from the start.
2
In a large mixing bowl, whisk together the oat flour, raw cacao powder, baking powder, sea salt and ground cinnamon until evenly combined and no lumps remain.
3
In a separate medium bowl, mash the ripe banana until completely smooth. Add the coconut sugar, melted coconut oil, egg, vanilla extract and almond milk. Whisk everything together until the mixture is uniform.
A very ripe banana with lots of brown spots gives the most natural sweetness and the smoothest texture.
4
Pour the wet ingredients into the dry ingredients and stir gently with a spatula until a soft dough forms. Do not overmix. The dough will be slightly sticky, which is normal.
5
Scoop heaped tablespoons of dough onto the prepared baking sheet, spacing them about 4 cm apart. Use slightly damp fingertips to shape each portion into a rough oval, like a small wrapped mummy body.
An oval shape gives you more surface area for the drizzle wrapping lines, making the mummy effect more convincing.
6
Bake for 11 to 13 minutes until the cookies are set around the edges but still look very slightly soft in the centre. Remove from the oven and allow to cool completely on the baking sheet for at least 10 minutes before moving.
They will firm up as they cool. Pulling them too early can cause them to break apart.
7
While the cookies cool, stir together the Greek yogurt and honey in a small bowl until smooth. Transfer the mixture to a small piping bag or a zip-lock bag with a tiny corner snipped off.
If the yogurt feels too thin, drain it through a fine mesh sieve lined with a cloth for 10 minutes to thicken it up.
8
Once the cookies are completely cool, pipe thin zigzag lines of the yogurt mixture across each cookie to create the mummy bandage effect. Work quickly and confidently for the most natural look.
9
Press two dark chocolate chips near the top of each cookie for the mummy eyes, pointed side down into the yogurt drizzle so they stick.
Do this immediately after piping while the yogurt is still soft enough to hold the chips in place.
10
Transfer the decorated cookies to the refrigerator for 15 minutes to allow the yogurt drizzle to firm up slightly before serving.

Pro Tips

✓
Use a piping bag with a very small round tip for the neatest mummy bandage lines. The thinner the lines, the more realistic they look.
✓
Make sure your banana is genuinely ripe. Green or just-yellow bananas will not provide enough natural sweetness.
✓
Do not skip the chilling step after decorating. The yogurt firms up nicely in the fridge and makes the cookies much easier to handle.
✓
Batch these cookies ahead of time. The bases freeze well and can be decorated fresh on the day of your party.
✓
For extra chocolatey depth, add a small handful of dark chocolate chips directly into the dough before baking.

Frequently Asked Questions

Variations

•
Pumpkin Spice Mummy Cookies
Replace the mashed banana with 80g of pure pumpkin puree and add half a teaspoon of nutmeg and a quarter teaspoon of ground ginger to the dry ingredients. This gives a warm, autumnal flavour that is incredibly festive.
•
Almond Butter Mummy Cookies
Add 2 tablespoons of smooth almond butter to the wet ingredients for a richer, nuttier cookie base. This also increases the protein content per cookie and adds a lovely depth of flavour alongside the cocoa.
•
Vegan Mummy Cookies
Replace the egg with a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water, rested for 5 minutes). Use maple syrup instead of honey and coconut yogurt for the drizzle. Every other ingredient is already plant-based.
•
Double Chocolate Mummy Cookies
Stir 3 tablespoons of dark chocolate chips into the dough before baking alongside the cacao powder base. This creates pockets of melted chocolate inside each cookie and makes them feel extra indulgent while still keeping the nutrition profile clean.

Substitutions

•
Oat flour → Almond flour (Use the same quantity by weight. The cookies will be slightly denser and more moist. Reduce almond milk by half as almond flour absorbs less liquid.)
•
Coconut sugar → Maple syrup (Use 2 tablespoons of maple syrup in place of 3 tablespoons of coconut sugar. Reduce the almond milk slightly to compensate for the extra liquid.)
•
Ripe banana → Unsweetened applesauce (Use 80g of unsweetened applesauce. The banana flavour will not come through, giving you a more neutral chocolate cookie base.)
•
Coconut oil → Light olive oil or avocado oil (A neutral-flavoured oil works well here at the same quantity. Avoid strongly flavoured oils as they can overpower the cocoa.)
•
Greek yogurt (drizzle) → Thick coconut yogurt (Ensure the coconut yogurt is a full-fat, very thick variety. Thin yogurts will not pipe well and will slide off the cookie rather than setting.)
•
Dark chocolate chips (eyes) → Cacao nibs or raisins (Two cacao nibs or small raisins pressed into the yogurt work just as well for a no-refined-sugar, fully natural finish.)

🧊 Storage

Store decorated cookies in an airtight container in the refrigerator for up to 3 days. Place a sheet of parchment between layers to prevent sticking. If storing undecorated cookie bases only, they can be kept at room temperature in an airtight container for up to 2 days or frozen for up to 6 weeks.

📅 Make Ahead

The cookie dough can be prepared up to 24 hours in advance and stored covered in the refrigerator. The baked cookie bases can also be frozen undecorated for up to 6 weeks. Thaw them at room temperature for 30 minutes, then decorate with fresh yogurt drizzle just before serving for the best presentation.
