Easy & delicious homemade vegan peanut butter frosting. In this recipe, coconut oil and peanut butter are combined to make the most incredible dairy-free frosting ever! Serve it on top of brownies, use it to frost a cake, or eat it with a spoon!
If I had to choose one food to eat for the rest of my life, it would be peanut butter. No big surprise. I currently have an embarrassing number of open jars of peanut butter in my pantry.
When a good friend gave me this recipe for Homemade Vegan Peanut Butter Frosting I just about died. I usually like plain peanut butter, but this changed my mind.
What I love about this Homemade Vegan Peanut Butter Frosting recipe is that it’s made with just a handful of ingredients that you probably already have on hand, and it comes together in 5 minutes.
Compared to other frosting recipes, this one is much healthier! It’s vegan, gluten-free & dairy free and if make your own powdered sugar (recipe here) it can be refined-sugar free too!
Vegan Peanut Butter Frosting: Ingredient s& Substitutions
- Peanut Butter: I use a firm peanut butter for this recipe, like a natural peanut butter that is no stir. If you use a peanut butter that is liquid at room temperature you may need to add more powdered sugar to get it to firm up, and/or omit the almond milk all together.
- Coconut oil. vegan butter or regular butter can be used in place of coconut oil.
- Almond milk: coconut milk or any other non-dairy milk works in this recipe. I have even used non-dairy creamers with fantastic results.
- Salt: I love the sweet/salty flavor of this frosting. You can always add a little at a time and adjust it according to your taste. If you’re using a salty variety of peanut butter you many need to add less.
How to make Vegan Peanut Butter Frosting
Combine peanut butter & coconut oil
Make sure the coconut oil is softened to room temperature, then either mix by hand or using a hand-held mixer or standing mixer, beat until they are combined.
Room temperature coconut oil. The coconut oil needs to be room temperature or slightly melted (not too warm), if it is hard then it will not mix well into the peanut butter and you will be left with chunks of coconut oil in your frosting.
Once the coconut oil and peanut butter are combined and smooth, add the vanilla, powdered sugar and salt and beat until you reach the desired consistency.
Add almond milk slowly. The amount of almond milk needed depends on the type of peanut butter used. Some people have reported not needing it at all. Please add it carefully so the frosting does not become too runny. If that does happen, add more powdered sugar and mix until you reach the desired consistency.

Recipe FAQs
You can remedy this two ways – 1) add more powdered sugar. 2) if the ingredients are too warm it will become runny, so you can chill it in the refrigerator to firm it up a bit.
I usually make a half recipe to frost brownies and a full to frost a cake. So yes, this recipe halves very well.
I decorate cakes often, here’s a list of the equipment I use to create these roses:
Piping bags – I have both reusable and disposable piping bags and use them all the time.
Piping tips and couplers – I recommend a great starter tip and coupler set. However I always make this rosette style cake with a Wilton 1M tip and large coupler.

Notes
- This makes A TON of frosting. I halve this recipe for an 8×8” pan of brownies or if I’m making it just for my family.
- I recommend starting with a small amount of almond milk and increasing it until you reach your desired consistency. Some very liquidy peanut butters may require no almond milk at all!

Even my husband can’t stay away from this when I make it, and he’s not really a peanut butter guy (which at first I thought was his only flaw. However, his indifference towards my favorite food means I don’t have to hide it in the back of the pantry share…so it’s just another one of the many reasons he’s perfect for this lady right here).

I needed to make a vegan filling for my pancakes and this recipe was the perfect match. But I don’t understand why salt is added to something sweet or dessert. I did this without the salt and result was amazing, thanks!!
Whoa! I’m so thankful there’s a peanut butter frosting out there that’s dairy free! 🤤 Heavenly!
Easy and delicious!!
The taste is amazing but the texture was more like cookie dough instead of frosting! I’m not sure what I did wrong. The coconut oil was at room temperature. I’m wondering if it would have worked better to melt it just a bit before mixing.
