No bake desserts are my personal favorite.

What is not to love about them? The oven gets ignored, there is little prep needed, and you satisfy the sweet tooth in no time.

If you’ve made our cornflake bars, caramel slice, or cookie dough bars, then a chocolate slice MUST be next on your agenda!

Why this recipe works

If you are not much of a baker but still enjoy homemade sweets, then my chocolate slice recipe is what you should try next. Made with plain chocolate cookies, oats, dark chocolate, and peanut butter, this chocolate slice turns out sweet, luscious, and so delicious! 

  • Easy and quick. Chocolate slice is the perfect dessert to make if you have leftover chocolate cookies and it doesn’t even matter if they are homemade or not. And while this chocolate slice may take a couple of hours to fully set, making it takes a matter of minutes. 
  • Only 6 ingredients. Unlike most dessert recipes that have a long list of dry and wet ingredients, this chocolate slice recipe only calls for a couple of everyday ingredients. 
  • No bake recipe. Like in a pot de creme, the best part about this chocolate dessert is that it requires no baking. So, there is no room for error even for those who think baking is not their strong suit. 

What I love about this recipe is just how versatile it is! You can serve them at events and parties or make a batch for a cheeky dessert! 

Ingredients needed

This rich and fudgy chocolate slice is made with a few simple ingredients. Here’s everything you will need. 

  • Oats. I use rolled oats for this recipe as they create a chewy texture. 
  • Chocolate cookies. Plain chocolate cookies crushed to a fine crumb. 
  • Sugar. Use confectioner’s sugar for this recipe as it melts a lot easier than granulated sugar. 
  • Dark chocolate. Finely chopped. 
  • Peanut butter. To add sweetness and help bind ingredients. 
  • Butter. Unsalted. 

For the topping:

  • Dark chocolate. As the slice is already pleasantly sweet, using dark chocolate has a fantastic contrast. 
  • Peanut butter. When combined with the melted chocolate, it creates an almost fudge-like texture (like we used for our keto fudge). 
  • Flaky sea salt. Sprinkle over the chocolate slices to decorate them. Salt also enhances the flavor of chocolate. 

How to make a chocolate slice

This chocolate slice recipe doesn’t require any baking which means that it is a breeze to make. Here is how you make this rich chocolate dessert in just a few steps. 

Step 1- Prepare the chocolate base

Put the finely chopped dark chocolate in a microwave-safe bowl. Add the peanut butter and butter. Microwave in 20-second intervals until fully melted. Once melted, add in the rolled oats, chocolate cookies, and confectioner’s sugar. Mix well until fully combined.

Step 3- Set, slice, and serve 

Pour the chocolate peanut butter topping over the chocolate slice and refrigerate until firm. Once frim, allow the chocolate slice to sit at room temperature for a few minutes. Then slice, sprinkle with flaky sea salt, and serve.

Tips to make the best recipe

  • Use a blender or a food processor to crush the cookies into a fine powder. Crushing the cookies by hand will result in inconsistent crumbs and interfere with the final texture of the chocolate slice. 
  • Substitute dark chocolate with milk chocolate if you want a sweeter topping for the chocolate slice. 
  • Remove the chocolate slice from the fridge and allow it to come to room temperature for around 20 minutes before you cut it. This will prevent the chocolate coating from cracking. 
  • Coat your knife with cooking spray to cut perfect slices. Wipe the knife clean after each slice and apply cooking spray again before cutting another piece. 

Storage instructions

To store: As this is a no bake dessert, the bars can be stored at room temperature in an airtight container. They will keep well for at least a week. If you’d like them to keep longer, store them in the refrigerator and they will keep well for at least four weeks. 

To freeze: Place the slice in a ziplock bag and store them in the freezer for up to 6 months.

  1. I clicked on this picture in spite of it saying healthy and I am so glad I did. I need to make this!

  2. My mother has the most plain palate of all the palates. When I make her cake, she always wants white cake with white frosting. Store bought. Nothing else. Needless to say I’ve never experiemented with providing her any food on Mother’s Day, except one time and I definitely learned my lesson. Man I worked HARD on some scratch made red velvet cupcakes but nnooooooo she wasn’t having any! Like you said, her loss!

  3. The best thing about moving to the UK is now I can claim ignorance when it’s Mother’s Day, as we celebrate on a different date! I’m such a good daughter haha

  4. I’m a fan of chocolate in general — I don’t discriminate 😉 And if you got -me- peanut butter cups… well… I’d probably think you were subtly trying to tell me something.

  5. So my mom is pretty much the same way. Just “study hard”. I played soccer my entire life, though, so I never got the join-the-team request ;).

    THESE. I don’t know how you come up with such great healthier versions of things like this! Teach me your ways. Salted vanilla sounds divine <3

  6. Arman, yes, always get your mom something for Mother’s day .. even if it’s a card or something homemade. . these vanilla slice things look great! Beautiful photos!!!

  7. I’ve been thinking about these bad boys since I saw ’em yesterday on your IG. They look so incredible!
    And I’m such a white chocolate fiend, I love that thing to death!

    1. Cheers, Mike- I tried out the paleo version of it and it worked out really well in no bake stuff- As for baked cookies- Well, they turned into a white chocolate waterfall.

      …I didn’t mind.


    Yep. You can assume how that turned out.

    I burnt my mouth. And then broke a tooth.

    I’m the best food blogger ever……..?

  9. I like how all your recipes have a vegan version. I know many people roll their eyes at vegans, but it matters to me and to the animals. Thanks Arman! 🙂

  10. Caramel and white chocolate. Say no more, unless it’s a Happy Mother’s Day to your poor mum, putting up with you and Niki’s shenanigans. You better get her the best present every this year!!

  11. I don’t discriminate with chocolate…usually I go dark, but lately I’ve been feeling milk chocolate. Nothing wrong with white too though. I have to figure out what to get my mom for mother’s day this year – whatever will ship easily.

  12. No bake slice! O goodness….my mouth really is watering! I really never have white chocolate since it’s either not vegan or not soy-free….but it’s okay…I don’t hate it…just strong dark dark ROBUST chocolate is better 😉

    1. Ohhhh try the vegan homemade version I linked- It’s the ONLY one which worked out (the other turned into a damn puddle!)

  13. I used to only eat white chocolate – growing up I hated milk and dark chocolate! Since going paleo I cannot stand white/ milk chocolate but absolutely adore really really dark chocolate, the higher the percentage the better! I reckon these would be good with dark choc too though!
    Also I think everywhere in the world has Mother’s Day coming up bar the UK – we had it in March!

    1. That’s great you enjoy the dark chocolate- I go through phases with it! At the moment, I’m digging it!

  14. Yummy! These sound good. And your Mum sounds like most Mums out there. She is going to miss you when you leave!!
