The peppermint slice holds a special place in Australian hearts — that perfect trinity of biscuit base, mint cream, and chocolate coating found in every country bakery and school fête. Our cannabis version elevates this nostalgic treat while maintaining the exact flavour profile that makes mums across the nation guard their secret recipes. The combination of rich chocolate and cool mint creates the perfect canvas for cannabis infusion, with the layers helping to distribute the cannabutter evenly throughout each piece.

This recipe uses cannabutter in both the base and the peppermint layer for consistent dosing across all 16 pieces, delivering approximately 10.5mg THC per slice when made with standard-strength cannabutter. The mint flavour beautifully complements cannabis while the chocolate layers provide rich coverage of any herbal notes.

Prepare your 20x20cm slice tin by lining with baking paper, leaving overhang for easy removal. This makes lifting the finished slice much easier.

Crush the biscuits in a food processor or by placing in a sealed bag and bashing with a rolling pin until you have fine-medium crumbs. Mix with cocoa powder and coconut in a large bowl.

Combine the cannabutter and regular butter, ensuring both are at room temperature for easy mixing. Pour over the biscuit mixture and stir until evenly coated and mixture holds together when pressed.

Pro tip: Test if your base is ready by pressing a handful — it should hold its shape without crumbling.

Press the base mixture firmly into your prepared tin using the back of a spoon or clean hands. Ensure even thickness across the entire base. Refrigerate for 30 minutes to set.

Beat the remaining room-temperature cannabutter until light and fluffy. Gradually add sifted icing sugar, beating well after each addition until smooth and creamy.

Add peppermint extract and food colouring (if using), then enough milk to create a spreadable consistency. Taste and adjust peppermint — you want a fresh mint flavour that’s not overpowering.

Pro tip: Start with less peppermint extract and build up — it’s easier to add more than to fix an overpowering mint flavour.

Spread the peppermint mixture evenly over the chilled base using a palette knife or offset spatula. Work quickly as the mixture can firm up. Return to fridge for another 30 minutes.

Melt the chocolate and butter together using a double boiler or microwave in 30-second bursts, stirring between each interval. Candy Thermometer can help ensure you don’t overheat the chocolate.

Pour the melted chocolate over the peppermint layer, using a spatula to spread evenly right to the edges. Tap the tin gently to release air bubbles and create a smooth surface.

Refrigerate for at least 2-3 hours or until chocolate is completely set. Use the baking paper to lift out of tin, then cut into 16 even pieces using a sharp knife warmed under hot water.

Pro tip: Warm your knife under hot running water and wipe clean between cuts for perfectly neat slices.

Perfect Peppermint Balance

Start with less extract than you think you need — peppermint can quickly overpower the delicate cannabis flavour. You can always add more.

Temperature Control

Keep your cannabutter at room temperature throughout — cold butter won’t incorporate properly, while warm butter will make the layers too soft.

Clean Cuts

For professional-looking slices, score the chocolate top lightly before it’s completely set, then finish cutting when fully chilled.

Half-Strength Option

Replace half the cannabutter with regular butter to create milder 5mg slices — perfect for beginners or daytime treats.

Storage Success

These slices actually improve after a day in the fridge as flavours meld together. Store in airtight containers between parchment layers.

Label Everything

Always label your container with contents, THC dose per piece, and date made. Keep away from unsuspecting family members.

Method Duration Notes
Room temperature 3 days Airtight container, cool location
Refrigerated 1 week Best for maintaining texture
Frozen 3 months Wrap individually in parchment

  • Duration: Effects can last 4-8 hours.
  • Do not drive or operate machinery after consuming cannabis edibles.

Can I use half cannabutter and half regular butter?

Absolutely! This is perfect for beginners or those wanting milder effects. Replace 15g of cannabutter with regular butter to create ~5mg slices instead of ~10mg. The texture and flavour remain identical.

How long do these peppermint slices take to kick in?

Cannabis edibles typically take 30-120 minutes to take effect, with peppermint slices usually on the faster end due to some absorption beginning in your mouth. The high fat content helps with THC absorption but also means effects can creep up gradually.

Do I need to decarboxylate my cannabis first?

Yes, always decarboxylate before making cannabutter. Raw cannabis contains THCA which needs heat activation to convert to psychoactive THC. If you’re buying pre-made cannabutter, this step is already done.

How should I store these cannabis slices?

Store in an airtight container in the fridge for up to one week, or freeze individually wrapped pieces for up to 3 months. Always label with contents, dose per piece, and date. Keep away from children and pets.

What if I accidentally eat too much?

Stay calm and find a comfortable place to rest. Drink water, try some black pepper (it can help reduce anxiety), and remember that while uncomfortable, cannabis overdose isn’t dangerous. Effects will pass in 4-8 hours. Call 13 11 26 for Poisons Information if concerned.

Can I substitute coconut oil for cannabutter?

Yes, cannabis coconut oil works well in this recipe. Use the same amount but note that coconut oil may make the layers slightly firmer when chilled. The tropical flavour also pairs beautifully with mint and chocolate.
