Making your own cannabutter at home is a rewarding experience. It lets you control the quality and potency of your edibles. Using a slow cooker simplifies the process and helps you avoid the guesswork. In this guide, I’ll walk you through everything you need to know to make perfect cannabutter with ease.
Why Use a Slow Cooker for Cannabutter?
Slow cookers are fantastic for infusing butter with cannabis. They maintain a steady, low temperature that prevents burning and preserves cannabinoids. This method is hands-off, so you can set it and forget it while it works its magic.
Here’s why I recommend a slow cooker:
Consistent heat: Keeps the temperature low and even.
Less monitoring: No need to stir constantly.
Better flavor: Slow infusion reduces the grassy taste.
Easy cleanup: Most slow cooker inserts are dishwasher safe.
Using a slow cooker also means you can make larger batches without worrying about scorching your butter. This is perfect if you want to prepare edibles for multiple occasions.

How to Make Slow Cooker Cannabutter Step-by-Step
Let’s get into the practical steps. Here’s what you’ll need:
Ingredients:
1 cup unsalted butter
1 cup water
7-10 grams of decarboxylated cannabis (adjust based on potency preference)
Equipment:
Slow cooker
Cheesecloth or fine mesh strainer
Glass jar or container for storage
Grinder
Instructions:
Decarboxylate your cannabis
Preheat your oven to 240°F (115°C). Break up the cannabis into small pieces and spread it evenly on a baking sheet. Bake for 30-40 minutes, stirring every 10 minutes. This activates the THC and CBD.
Prepare the slow cooker
Add the butter and water to the slow cooker. The water helps regulate temperature and prevents the butter from burning.
Add the cannabis
Stir in the decarboxylated cannabis. Mix well to ensure even infusion.
Cook low and slow
Set your slow cooker to low. Let the mixture cook for 4-6 hours. Stir occasionally to prevent sticking. Keep the lid slightly ajar to allow some moisture to escape.
Strain the mixture
After cooking, strain the butter through cheesecloth into a glass container. Squeeze out as much butter as possible from the cannabis.
Cool and store
Let the butter cool at room temperature, then refrigerate. The butter will solidify, and any remaining water will separate. Drain off the water before using.
Tips for Success:
Use unsalted butter for better flavor control.
Don’t skip decarboxylation; it’s essential for potency.
Keep an eye on the slow cooker temperature; it should stay between 160°F and 200°F.
Label your cannabutter with the date and potency estimate.

Can You Infuse Cannabutter Too Long?
Yes, you can. Infusing cannabutter for too long or at too high a temperature can degrade cannabinoids and terpenes, reducing potency and flavor. The slow cooker method helps avoid this by maintaining a gentle heat.
Here’s what to watch for:
Overheating: Temperatures above 200°F can burn cannabinoids.
Extended cooking: Infusing beyond 8 hours may cause a bitter taste.
Evaporation: Too much water loss can lead to scorching.
If you notice a strong burnt smell or the butter turns dark brown, it’s a sign you’ve infused too long or too hot. Stick to 4-6 hours at low heat for the best results.
How to Use Your Cannabutter
Once you have your cannabutter, the possibilities are endless. Here are some ideas to get you started:
Baking: Use it in brownies, cookies, or cakes.
Cooking: Substitute it for regular butter in savory dishes.
Spreading: Melt it and spread on toast or popcorn.
Sauces: Add it to pasta or vegetable sauces for a cannabis twist.
Remember to start with small amounts when trying new recipes. The potency can vary, so it’s best to test your tolerance gradually.
Storing and Preserving Your Cannabutter
Proper storage is key to maintaining freshness and potency. Here’s how to keep your cannabutter at its best:
Store in an airtight container in the refrigerator for up to 2 weeks.
For longer storage, freeze in small portions using silicone molds or ice cube trays.
Label containers with the date and dosage estimate.
Avoid exposure to heat and light, which can degrade cannabinoids.
By following these tips, you’ll have high-quality cannabutter ready whenever you want to create delicious cannabis-infused treats.
Making your own cannabutter with a slow cooker is simple and rewarding. With patience and care, you can create a potent, flavorful base for all your favorite edibles.
