Vegan Oreo Brownies

Vegan Oreo Brownies

If you’re not a vegan then you might not know that Oreo biscuits are suitable for vegans. Yes that’s right, these delicious chocolate sandwich biscuits are completely free from animal products! They are known as “accidentally” vegan, which is a group of products that were not made to be suitable for vegans, but by chance they are. This often happens because retailers use cheaper ingredients (for example oil instead of butter), so most accidentally vegan products are not exactly the healthiest of options! But hey, vegans need junk food too! I decided to make Vegan Oreo Brownies and drizzle on some dark chocolate for good measure, the perfect treat!

Step by step…

To start, I made the flax eggs. I whizzed up 2 tbsp linseeds in my Nutribullet, added 4 tbsp water and put the mixture in the fridge for 10 minutes. Linseeds and flaxseeds are the same thing, but they are called linseeds in the UK and flaxseeds in the US. You can get golden ones, or brown ones, and either are suitable.

For the brownie batter I put the plain flour, caster sugar, cocoa powder, baking powder and salt in a bowl and stirred it together.

In another bowl I whisked up the almond milk, flax eggs, vegetable oil and vanilla extract.

I poured the wet ingredients into the dry ingredients and whisked it all together.

Then I poured the batter into a lined baking tray, and covered it with the broken up Oreo pieces.

I baked it for 35 minutes, then left the Vegan Oreo Brownies to cool completely.

You can slice the Vegan Oreo Brownies up before or after drizzling on the chocolate, it doesn’t make a difference. I melted the dark chocolate and put it into a small piping bag then snipped off the end and drizzled it all over. Make sure to use a dark chocolate with a high cocoa percentage so that it is suitable for vegans (I used Green & Blacks 70%) Check the label, if it says ‘may’ contain milk then that is ok as this warning is for people with allergies and doesn’t mean the product contains milk.

Vegan Oreo Brownies

The Vegan Oreo Brownies were so yummy and didn’t stick around for long! I got the thumbs up from my sister who is vegan, and I really enjoyed them too (I even stole my boyfriend’s piece, whoops! Guess I’ll be making another batch soon!) They are really moist and fudgey, they taste super chocolatey and indulgent, and the pieces of oreo and chocolate drizzle are absolutely scrumptious! Any oreo fan is sure to love these, and they’re so easy to make too!

Are Oreos vegan?

There has been some debate over whether Oreos are vegan, with the company themselves saying “Oreos have milk as cross-contact and therefore are not suitable for vegans”. However, Oreos do not contain any animal derived products so they are suitable for vegans. If you have a serious dairy allergy though, you may need to avoid them. Of course, as with everything, it’s up to you whether you eat them or not.

    Wow these look amazing!! Def pinning for later! Love a good vegan brownie making an espresso batch this morning!! Somehow chocolate bakes taste so much better vegan, maybe it’s the dark chocolate yum!!

    Had to read the bit about the may contain warning a couple of times as it sounded like ‘may contain’ makes it suitable for those with allergies… It’s not what you meant I just hadn’t had coffee!!

    1. I’ve updated that sentence to make it clearer! Thanks for letting me know and I hope you try this recipe!

  3. have baked these 3 weeks in a row every weekend, I do a mix of dark brownies and white brownies with choc chips in it.. my kiddos love it. I also use stevia instead of sugar. Its a family hit. Thank you

    1. Hi Iliana, this is the conversion:
      250 g Plain flour – 2 cups + 1 tbsp
      350 g Caster sugar – 1 + 3/4 cups
      90 g Cocoa powder – 3/4 cups
      1 tsp Baking powder
      1 tsp Salt
      1 tsp Vanilla extract
      250 ml Almond milk – 1 cup
      2 Flax eggs see instructions
      250 ml Vegetable oil – 1 + 1/4 cup
      154 g Oreos broken up – This is one packet, or one ‘roll’
      65 g 70% Dark chocolate – 1/2 cup dark choc chips

      I’m assuming you are ok with the tsp/tbsp amounts?

    1. Hi, yes I don’t see why not. I’ve never made them with oat milk but I think it would work fine, please let me know how it goes!

    1. Yes of course, althought they would no longer be vegan if you use any milk from an animal

  6. Hi Kat
    I have just recently come across your website and found this recipe – they are without doubt amazing! They have gone down a treat in our house! I just wanted to ask how long will they last and should they be stored in an airtight container? Thank you! Paula

    1. Hi Paula, I’m so happy to hear this! Yes store them in an airtight container in a cool place and they will last 3-4 days.

    1. Hi Sharon, I’ve not had this feedback before, did you bake it in a smaller tin? If so, the mixture will need longer in the oven. As they’re vegan, if they’re a bit gooey in the middle it’s not bad as there isn’t any raw egg in them, and also brownies can be quite tasty when gooey (well I like them this way!)

  7. 5 stars
    Will definitely be making these again! They turned out incredible, really enjoyed the recipe- I used egg replacer (from holland&barett) as i didn’t have any flax and it still turned out amazing! 5 stars for sure!

  8. 5 stars
    I’ve been looking for a good vegan brownie recipe as I’m allergic to eggs and this turned out amazing! The oreos gave such a good crunch.

    Thanks so much Kat!
