Small Batch Cannabutter Slow Cooker: 4-Hour Crock Pot Guide

Slow Cooker Water Bath Cannabutter: Step by Step

This slow cooker water bath cannabutter process takes about 4 hours hands-off:

1. Weigh the ghee: Measure approximately 113g (one stick equivalent) of ghee. If it’s too firm, microwave for 30 seconds to soften — you don’t need it fully liquid, just soft enough to work with.
2. Add cannabis to jar: Place your decarbed cannabis in the mason jar, then spoon or pour the softened ghee on top. Seal the lid.
3. Set up the water bath: Add about 2 inches of water to the bottom of the slow cooker. Place the sealed jar in the water. The water doesn’t need to cover the jar — just enough to create a stable heat bath.
4. Cook on HIGH for 2 hours: Put the slow cooker lid on and set to HIGH. After about 2 hours, switch to LOW for the remaining 2 hours. This reduces the risk of overheating.
5. Shake every hour: Using an oven mitt, carefully remove the jar every hour and shake it to agitate the cannabis and ghee. This helps even infusion. Return it to the water bath each time.
6. Strain after 4 hours: Remove the jar (it will be warm/hot — use the oven mitt). Open and pour through a fine sieve into a second container, pressing the plant matter with a spatula to extract all the butter. For a clearer result, do a second strain through cheesecloth.
7. Mold and set: Pour the strained cannabutter into a butter mold or small container. Refrigerate for 30+ minutes until fully set. Pop out and store in an airtight container.

Small Batch Cannabutter With Eighth: Dosage Notes

When making small batch cannabutter with eighth (3.5g), the potency depends heavily on the THC% of your cannabis. As a rough guide: if your flower is 20% THC, that’s 700mg of THC in 3.5g. After infusion losses (~30%), you’d have roughly 490mg across ~113g of butter. That’s about 4.3mg per gram of butter, or around 8–10mg per tablespoon — a moderate single dose. Always test a small amount first before using in recipes.

Cannabutter Crock Pot Method Tips

A few tips for the best results with the cannabutter crock pot method:

• Don’t skip decarbing — raw cannabis won’t get you high. Decarboxylate at 240°F/115°C for 40 minutes before adding to butter.
• Temperature matters — if your slow cooker runs hot, switch to LOW earlier (after 1–1.5 hours on HIGH). You can also start on LOW for the entire 4 hours.
• Color isn’t everything — Fordee’s butter came out lighter than expected due to the strain used. Light-colored cannabutter can still be very potent.
• Don’t skip straining — plant matter left in the butter makes it taste grassy and can cause digestive issues.
• Save the scraps — the plant material left in the strainer still has some residual butter. Don’t toss it — scrape it out and add it back to the batch.
