Gooey CBD Brownies: Baking With CBD

Hi, I’m Vicky. I take care of content for ULU – and in my spare time I’m an avid baker. I’ve been baking for over 10 years, and I used to run a small baking business out of my kitchen. (I even made my own wedding cake!)

One of my absolute favourite things to bake are brownies. I love a warm, gooey chocolate brownie with fresh raspberries, or a chilled one to grab on the go. And when it comes to brownies, I’m really picky! I don’t like eating brownies where the batter is pretty much raw in the middle, and I don’t like them when they’re too cakey! A good brownie should be the perfect mix between the two. And this recipe definitely fits that profile.

Over the last 10 years, I’ve been perfecting my brownie recipe. I’ve been tweaking and adding to it every so often. And I’ve been testing any recipe tweaks on anyone I can force-feed (although I’ve never had anybody who wasn’t excited to eat more of my brownies.)

I’ve also been experimenting with CBD recipes more recently. I take CBD oil every day to help with anxiety and sleep – and I’ve noticed some amazing benefits. So, I like to bake and cook with CBD as a novel way to supplement by daily CBD oil drops. And these brownies are a great way to get into cooking and baking with CBD in general.

Now, I believe this brownie recipe is perfect. I’ve had lots of people tell me that these brownies are the best they’ve ever tried! No exaggeration. I am constantly bombarded with requests to make these brownies at any event, gathering or birthday.

So, here is my famous CBD brownies recipe (with some FAQs included at the end of the recipe)


Gooey CBD Brownies Recipe

This recipe uses a 26cm by 20cm baking tray and makes around 15 square brownies.

  • 300g dark chocolate
  • 150g butter (plus a little extra for greasing the tray)
  • 350g brown sugar
  • 4 eggs
  • 120g plain flour
  • 2 teaspoons vanilla extract
  • 2 tablespoons cocoa powder
  • 30 drops of ULU 10% concentration CBD oil
  • 2 tablespoons mayonnaise (yes – really! Please see FAQs below)
  • Tin foil

CBD Brownies Method

Combine 300g dark chocolate and 150g butter and gently melt. You can do this by heating a saucepan full of boiling water, and then sitting the bowl of chocolate and butter on top of the saucepan – the steam from the hot water will melt the chocolate. Make sure to stir continually while the chocolate melts and only keep heat on medium to low to avoid the mixture becoming too hot.

Once melted, remove the bowl from the saucepan and allow to cool slightly. But not so much that the mixture hardens

Whisk the 4 eggs with a fork to combine yolk and egg whites and then add to the cooled chocolate and butter mixture. Stir until combined.

Sift together the flour, brown sugar and cocoa powder and then add to the chocolate, butter and egg mixture until combined.

Add 30 drops of ULU 10% concentration CBD oil. (This provides approximately 2 drops of CBD /3.2mg of CBD per brownie. You can experiment with different oil concentrations and number of drops if you like!)

Add the vanilla extract and the mayonnaise and stir until combined. (If you’re thinking ‘why mayonnaise?’ please see FAQs below!)

Grease a 26cm by 20cm baking tray and gently pour in the brownie mixture. This will make around 15 fairly thick square brownies. (It’s okay to use a larger tray, however you’ll need to bear in mind that the cooking time will need to be lowered as the brownies will not be as thick.)

Cook at 180° Celsius / 356° Fahrenheit / Gas mark 4 for 20 mins. Remove brownies after 20 mins and cover the tray with tinfoil. (This stops the top of the brownies from burning and becoming too chewy.)

Return brownies to oven and cook for a further 20 minutes. Insert a toothpick or sharp knife into the centre of the brownies. There should be a little wet batter clinging to the toothpick or knife, but they should both come out clean when inserted into the edges of the brownie tray.

Wait until cooled completely to cut into squares or rectangles!

Serve and enjoy your gooey CBD brownies.

Recipe FAQs

Why on earth is there mayonnaise in this recipe?

Ok, this is something that gets a lot of disgusted reactions from people I share the recipe with – especially if they can’t stand mayonnaise. But you’ll have to trust me on this one. And in fact, lots of people are starting to realise the benefits of including mayonnaise in their baking!

Mayonnaise is simply made up of oil and eggs. So, when added to this CBD brownie recipe, all it does is make the brownies extra gooey and moist. No, you won’t be able to taste the mayo! I’ve tested this on everyone who has tried my brownies, trying to get them to guess the unusual ingredient, and not one person has ever guessed mayonnaise. – Not even people who absolutely hate mayo.

Will I taste the CBD?

CBD is known for having a very particular, almost grassy taste. And lots of people avoid cooking or baking with CBD because they think it will spoil the taste of the recipe. But honestly, there is a lot of dark chocolate and cocoa powder in these brownies. And this completely overpowers any other tastes. So, no – you won’t be able to taste any CBD.

Will I feel any effect from the CBD?

I regularly use CBD for anxiety, and I have noticed such an improvement in my mood and anxiety levels! CBD also has powerful anti-inflammatory properties, so it’s great for chronic pain. However, it isn’t a quick fix. You’ll need to take CBD regularly to notice any benefits. So, no – you won’t notice any benefits or feel any effects from one brownie. But this recipe is a bit of fun – and cooking or baking with CBD is a great as a novelty way to take cannabidiol alongside daily oil drops or capsules.

Will these brownies get me high?

Nope! All ULU CBD products contain untraceable levels of THC (the chemical compound in marijuana that causes a high.)  None of our CBD products cause a high and these brownies won’t either!

Can I use a higher/lower CBD concentration?

You can absolutely use any CBD oil concentration you like in these brownies. I’ve used the ULU 10% CBD oil drops enriched with GABA as these are my personal favourite! However, you can include any CBD oil drops with any concentration you have to hand. You can also decrease or increase the number of drops you use in this recipe for a higher or lower dose.
