There is only one ingredient in this recipe that you probably won’t find in your pantry at home. That ingredient is cannabis butter. If you’re not sure how to make it or want to learn how we have a comprehensive guide to making cannabis butter here that will help you.

The recipe we have here also calls for 3 cups of white sugar. If you’d like, you can also infuse this recipe by using cannabis sugar. This ingredient is much harder to make than cannabis butter so if you are just a beginner, we recommend that you use cannabis butter. However, we have a guide here to making cannabis sugar. You can also make weed brownies with a few other ingredients which we will talk about further down in this post.

  • Oven
  • 9×13 Baking Dish
  • Mixing Bowls
  • Wire Rack
  • Toothpick


  • 1 Cup Cannabis-Butter *Melted
  • 3 Cups White Sugar
  • 4 Eggs
  • 1 Tablespoon Vanilla Extract
  • 1 1/2 Cups All Purpose Flour
  • 1 Cup Unsweetened Cocoa Powder
  • 1 Teaspoon Salt
  • 1 Cup Semisweet Chocolate Chips


  • To make these delicious weed brownies you will only need a few things. You will need an oven, 9×13 inch baking dish, some mixing bowls, a wire rack and a toothpick.
  • First, preheat the oven to 350 degrees Fahrenheit (175 degrees Celsius). Then lightly grease the 9×13 inch baking dish or line it with aluminum foil. This will ensure the brownies do not stick to the pan.
  • Next in a large mixing bowl combine the melted cannabis-butter, sugar, and vanilla. Then beat in the 4 eggs one at a time while thoroughly mixing after each one. Ensure the mixture is well blended.
  • Now using a separate mixing bowl, sift together the all-purpose flour, cocoa powder, and salt. Once it is sifted together, gradually stir the flour mixture into the egg mixture until its well blended.
  • Optional* stir in the cup of chocolate chips. This step is optional depending on your preferences.
  • Now once the batter has been thoroughly blended, spread it into the prepared 9×13 inch baking dish.
  • Place the dish in the preheated oven. To check when the weed brownies are done, insert a toothpick and if it comes out clean they're ready (can easily pull out), usually 35-40 minutes. Remove the baking dish from the oven and place on a wire rack to cool off before dividing it up into the desired serving sizes.

Cannabis-Infused Brownies Potency Calculator

To find the potency of your weed brownies, you’re going to first need to know the potency of your cannabis butter. If you don’t know the potency of your cannabis butter, head over to our cannabutter guide. At the bottom of that post, there is a calculator that you can use to estimate the potency of your activated ingredient.

Another important thing to note about potency calculations:

Calculating the potency of your edibles accurately is not an easy task. There are many variables involved. Some of these include the amount of cannabis that was actually infused into the cannabis butter, what the exact percentage of THC the cannabis you used was, and even the amount of cannabinoids that are burned off when you cook the brownies. In short, there’s a lot of places that your estimate can go wrong, and if there is an error at the beginning of your calculation, that error will be carried throughout and your result will be way off. It’s important to understand that the potency calculator is just to help you estimate the potency.

Other Ways to Make Weed Brownies

Depending on the ingredients that a recipe calls for, you can make weed brownies with a wide variety of ingredients. Cannabis brownies are just regular brownies except there is an activated ingredient being used in place of a regular ingredient.

If you have a brownie recipe that you would like to infuse with cannabis, you can! Let’s suppose that the recipe you have uses milk. If you were to make cannabis milk, you could then infuse your brownie recipe! You will need to find an ingredient from your recipe that matches with one of the ingredients we have linked to below. Each one of the ingredients is linked to guides on how to make them at home.

Another way to make cannabis brownies is by adding decarboxylated cannabis directly to the brownie mix. We definitely do not recommend this as the resulted brownies will be repugnant. It is best to infuse an ingredient with decarboxylated cannabis rather than use the cannabis directly. The last thing you want is cannabis leaves stuck in between your teeth.

Can I Make Weed Brownies With Store Bought Brownie Mix?

As we mentioned earlier, you can make pot brownies with whatever recipe you’d like! You will just need to swap out a regular ingredient with a cannabis-infused ingredient. If you are going to use a store-bought mix, we recommend using this Ghirardelli Brownie Mix. Although it really does not matter which brownie mix you use, you just need to make sure you can add a cannabis ingredient to it.

When using a store-bought brownie mix, we recommend that you choose one with a strong flavour. What we mean by this is that if you were to use a vanilla brownie mix, it would not cover the taste of cannabis nearly as well as a dark chocolate mix.

If you use the mix that we recommend, you would substitute the 1/2 cup of vegetable oil with a half cup of cannabis-infused vegetable oil. We have a comprehensive guide here to making cannabis vegetable oil.

How to Dose Pot Brownies

When it comes to cannabis edibles, there is always uncertainty on how to properly dose. The best way to dose cannabis edibles is to start small. In the case that you don’t know the potency of your cannabis butter, it’s important to start by eating a very small amount and wait for the effects. Keep taking these small portions until you find the correct dosage for you. Everyone’s size and preference will be different so discover your personal amount needed!

Another important thing to note, make sure to wait for at least 4 hours before you decide that the brownies are not strong enough. In some cases, edibles can have a delayed onset. After you understand how much of a brownie you need, reference this point for future use. Then you will know exactly how much you need for the next time moving forward.

Will my Brownies Taste Like Weed?

Depending on how potent your cannabis butter is, your brownies may taste like cannabis. This recipe does a pretty good job of masking the taste but it’s possible for the brownies to retain some of the cannabis flavours.

Brownies do a better job than most recipes when it comes to masking the flavour of cannabis. Weed gummy bears, for example, are not as good at covering the flavour because there are only a few ingredients being used.

Will Cooking Weed Brownies Make my House smell?

There will be a strong smell of cannabis when you decarboxylate and infuse cannabis into an ingredient. The smell from this can last for a few hours or even up to a couple of days.

However, if you have already decarboxylated and infused your ingredient, the smell will not be nearly as bad. If you use fans and allow the kitchen to air out while you cook the brownies, it is possible for the kitchen to be smell free an hour after cooking.

How Long Does it Take For Weed Brownies to Have an Effect

Weed brownies, like other cannabis edibles, usually produce effects at around one hour after consumption. The main problem with consuming weed edibles for the first time is that everyone’s body is different. What we mean by this is that for some people edibles can have an effect after 30 minutes and for others, it can take up to four hours. Weed brownies will have an effect depending on each individual’s digestive system, if they have eaten other food recently, and many other factors. The point we’re trying to make is that there is not a defined time of when cannabis edibles will have an effect.

Since we know that in some cases it can take up to four hours for the brownies to have an effect, it’s important to eat them one at a time. Let’s suppose that someone eats a brownie, waits 45 minutes, and then decides that the edible did not work. Since this person believes the edible did not have an effect, they eat another one. However, the first brownie had a delayed onset and now this person has just consumed way more cannabis then they would have liked to. Most people experienced with cannabis will be able to tell you a personal story similar to the example we just gave. It’s important to wait the full four hours before you decide to have another brownie!

Why Didn’t My Weed Brownies Work?

While looking around on the internet at some other weed brownie recipes, we noticed that a few of the top ones will not even work. Here’s how the other recipes go:

chocolate chips weed brownies divided into six separate slices on top of a cooking table. A bowl of rice lays across from them.

The recipe that we noticed calls for combining cannabis and butter in a pan, and then adding this combination directly to the brownie mixture.

I should probably clarify what I mean when I say they won’t work. So, if you try one of these other recipes (which I will not mention by name) the brownies will probably look and taste great! However, the problem is that these brownies will not allow you to feel the psychoactive effects of cannabis. The problem with these recipes is that they do not take into consideration the most important part of making cannabis edibles, which is activating the THC. We have a great post here that goes into detail about the importance of decarboxylation.

Important Things to Know About Making Cannabis Edibles

So if this is your first time making cannabis edibles, there are a few important things you should know:

  1. You cannot just add cannabis directly to recipes. Cannabis needs to be decarboxylated first. We have a post here designed specifically to explain this.
  2. If you’re going to add decarboxylated cannabis to a recipe, this will definitely work. But, it will taste exponentially better if you use an activated ingredient instead.
  3. The potency of your edibles is entirely in your control. If you would like to reduce the potency of your edibles, you can substitute a portion of regular butter in place of cannabis butter. This is the easiest way to make edibles less potent.

Although edibles can seem a little overwhelming at first, they’re much easier than you’d think. If this is your first time making edibles, make sure to comment and let us know how they went!
