Quick Answer: Make RSO-infused butter or coconut oil in just 5 minutes — no decarbing needed! Melt 1 stick of butter (or 4oz coconut oil), warm your RSO syringe in hot water for 5–10 minutes, then stir in your RSO until fully combined. Use immediately in recipes or let cool to harden. A simple, potent base for any homemade cannabis edible!
Have you ever wanted to make infused butter or coconut oil but didn’t want to deal with the lengthy process of infusing it with cannabis flower? This RSO infusion method is quick and easy; have your butter ready in 5 minutes!
Step 1. Pick out your RSO
There are so many amazing brands out there that offer a wide variety of options to choose from! Take your time deciding whether you want to go for an indica, sativa, or hybrid strain, or if you lean more towards a CBD strain of RSO. It's all about finding what works best for you and your preferences!
Step 2. Soften RSO
Just place the syringe in a cup of hot water for about 5-10 minutes. This will help the RSO become less solid and flow much more easily when dispensing it from the syringe.
Step 3. Melt your butter or coconut oil.
In this tutorial, we used butter but If you don't eat butter, coconut oil is a great substitute. When it comes to using butter, we suggest using 1 stick for every 1 gram of RSO that you plan to use. However, if you opt for coconut oil, we recommend using 4 ounces for every 1 gram of RSO. However, that is totally up to you, depending on your tolerance and how you plan to use it. See below for our dosing guide for more information! Now, here's what you need to do: Start by melting your butter or coconut oil slowly. We used a microwave and heated it in 10-second intervals for 30 seconds or until melted. Once it's completely melted, set it aside and get ready for the next step.
Step 4. Mix in the RSO
Just go ahead and mix in your RSO syringe all the way into the melted butter or coconut oil, and give it a gentle stir. Once everything is fully mixed, you can either let it sit to harden or add it directly to your recipe if it calls for melted butter.
Now you’re done! It’s that easy! See below for a dosing guide!
RSO infused Dosing guide:
If your 1 gram of RSO is 70.0% THC, that would equal 700mg of THC. Simply move over the decimal point one number to the right to find your total THC mg count. Use this calculation to determine how much THC is in your butter or coconut oil. If you have a low tolerance, you can always choose to use a small amount instead of the whole syringe to make your edibles less strong.

FAQ RSO Infused Butter & Coconut Oil
Why is RSO a better option than cannabis flower for making infused butter?
RSO is a game-changer for home cannabis cooking! Unlike infusing with raw cannabis flower — which requires hours of slow heating to activate and extract the THC — RSO is already fully activated and concentrated. That means no decarbing, no straining, no mess, and no waiting. The whole process takes about 5 minutes from start to finish, making RSO-infused butter one of the fastest and most reliable methods for making cannabis edibles at home.
How much RSO should I use per stick of butter or per cup of coconut oil?
The recipe recommends using 1 stick of butter for every 1 gram of RSO, or 4 ounces of coconut oil for every 1 gram of RSO. That said, these ratios are flexible depending on your personal tolerance and how potent you want your finished edibles to be. If you're newer to cannabis edibles or have a lower tolerance, start with less RSO and work your way up gradually over time.
How do I calculate how much THC is in my RSO-infused butter?
It's simpler than it sounds! Check the THC percentage on your RSO product label. If your 1 gram of RSO is 70% THC, that equals 700mg of THC total — just move the decimal point one place to the right from the percentage. That 700mg is now spread across your entire batch of butter or coconut oil. Divide by the number of servings in your recipe to get the approximate dose per portion.
Is there a difference between using butter vs. coconut oil with RSO?
Both are excellent fat-based carriers that bind to RSO effectively — the main difference is practical. Butter adds a rich, classic flavor that works beautifully in baked goods and savory dishes. Coconut oil is the better choice for vegan and dairy-free recipes, and its naturally high MCT fat content makes it particularly effective for CBD and THC absorption. For neutral-flavored applications, coconut oil is often the preferred pick.
Does RSO-infused butter need to be decarbed or heated further after mixing?
No — that's one of the biggest advantages of using RSO! RSO is already decarboxylated during its production process, meaning the THC is fully activated and ready to go the moment you mix it into your fat. You don't need to apply any additional heat beyond melting the butter or coconut oil. Just stir thoroughly and your infused fat is immediately ready to use in any recipe.
How should I store RSO-infused butter or coconut oil?
Store it in an airtight container in the refrigerator for up to two weeks, or in the freezer for longer-term storage. Always label it clearly as cannabis-infused with the approximate THC content noted on the container — this is important for both safety and accurate dosing when you use it in future recipes. Keep it out of reach of children or anyone who might mistake it for regular butter or oil!
