Why this recipe works
This vegan and gluten-free oat flapjack recipe is perfect if you have ripe bananas lying around that need using up. These 5 Ingredient Chocolate Flapjacks are so incredibly versatile. They are perfect for breakfast bars, a dessert or even a healthy snack for on the go!
I was inspired to create this recipe as my Vegan Snickers Flapjacks were so popular! However, I wanted to create another recipe, that was equally as good but used more of everyones favourite ingredient… chocolate! Paired with my Christmas Hot Chocolate (is it too early to be mentioning Christmas yet!?) these 5 Ingredient Chocolate Oat Flapjacks will transform your flapjack world!
For another healthy snack on the go check out my Healthy Energy Balls.
I added this recipe into my Best 33 Vegan Desserts and 35 Gluten Free Desserts round up!
Ingredients to make chocolate flapjacks
- Oats – I’ve used gluten free rolled oats here as I am gluten free, however standard rolled oats or porridge oats would also work just as well. If you have any spare, try making my Oat Crumble Topping or Protein Overnight Oats.
- Cacao powder – this is essentially chocolate in it’s raw form, before any sugar or milk is added to it. It is bitter, but rich and full in flavour and contrasts against the other sweeter ingredients well. If you have some spare then try making my Homemade Nutella.
- Chocolate – the hero ingredient in these 5 Ingredient Chocolate Flapjacks, what’s not to love about chocolate?! I’ve used vegan chocolate for this recipe as I am dairy free. You can also try my Gluten Free Banana Pancakes.
- Maple Syrup – this adds sweetness but also adds a stickiness that helps to combine and hold all of the ingredients together for the Chocolate Flapjacks.
- Bananas – ripe bananas work perfectly for this recipe as they are softer, so mash more easily. If you have any spare then try my Breakfast Banana Bars
See recipe card for full information on ingredients and quantities.
Substitutions
- Maple syrup – this could be swapped for either honey or agave syrup.
- Gluten free rolled oats – I use gluten free rolled oats as I am gluten free. However, standard rolled oats or porridge oats will work exactly the same with these oat flapjacks!
- Cacao powder – This could be excluded and replaced with chocolate chips or extra chocolate chunks!
- Chocolate – I have used vegan chocolate in this recipe, but standard chocolate would work well too. If you don’t like chocolate, these are still really tasty without it.
Variations
- Kid friendly – If you have kids, these 5 Ingredient Chocolate Flapjack are perfect for them to get stuck in and bake something delicious. However, if you have a child that would prefer cookies over flapjacks, then you have to check out these Chunky Chocolate Chip Cookies. They are seriously good! Plus, they’re vegan, gluten free and refined sugar free too!
- Deluxe – To take these 5 Ingredient Chocolate Flapjacks to the next level, serve them fresh out of the oven with some whipped coconut cream to keep it vegan and dairy-free or alternatively a scoop of your favourite ice-cream.
How to make chocolate flapjacks
Step 1: Firstly, preheat your oven to 180C / 360F. In a large mixing bowl, mash the bananas together using the back of a fork.
Step 2: Add the other 4 ingredients to the mashed bananas.
Step 3: Mix to combine the ingredients together. Once you have formed your homemade chocolate flapjack mixture, line a square baking tin with baking paper. I use a 9×9 baking tin.
Step 4: Add the chocolate flapjack mixture into the baking tin and press down with a fork. Hint: I aim for about 1cm depth. Make sure to compress down firmly to hold them together. Place in the pre-heated oven at 180C for 15 minutes.
Step 5: Remove from the oven and allow to cool outside of the baking tray for 10 minutes before slicing into squares. This helps the flapjacks firm up a little and helps with slicing into squares.
Leftovers
Allow these 5 Ingredient Chocolate Flapjacks to cool and store in an air tight container for up to 3 days. You can also freeze these to have on another day just like my 3 Ingredient Oat Cookies. Simply bake and then make sure they are cold. Cut them into squares and place into an air tight container suitable for freezing. Defrost naturally or microwave to defrost for on the go.
Recipe FAQs
Can I freeze these 5 Ingredient Chocolate Flapjacks
You can also freeze these to have on another day. Simply bake and then make sure they are cold. Cut them into squares and place into an air tight container suitable for freezing. Defrost naturally or microwave to defrost for on the go.
Can I eat these Chocolate Flapjacks straight away?
Yes, but you will need to wait 10 minutes (I know the temptation is strong!) Simply, remove from the oven and allow to cool outside of the baking tray for 10 minutes before slicing into squares. This helps the flapjacks firm up a little and helps with slicing into squares.
What if I don’t have cacao powder at home?
Fear not! You could either add some hot chocolate powder, or you could just simply add chocolate chips or additional chocolate chunks!
What if my bananas aren’t ripe?
Ripe bananas are preferable in this recipe, however if you can’t wait that long, just ensure the bananas are mashed really, really well!

Roughly 100g per banana so 400g for 4.

Could you post the measurements in US cups, ounces also. It’s hard to get accurate measurements on the conversion charts.
In some recipes I don’t know if it’s volume or weight. Would be so much easier.
ThanksReply

I made this today and it was just a easy as the recipe suggested. I am vegan and gluten free and they were great, I didn’t use turned oats but general Porridge GF Oats and it still worked well. Will look at some other recipes of yours for sure.Reply

Really wanted to love these…followed the recipe, but they were incredibly dry.
I did use frozen banana pieces, if thats what made the difference. Gutted as yr snicker like flapjack recipe was amazing!Reply
- James says
Sorry about that Julie, it’s not happened to me or I haven’t had anyone mention that to me. The frozen banana may have had a negative impact on the recipe.

Substituted the choc chips for almonds and normal oats ( not gluten free )
The wonderful thing with many of these recipes you don’t have to be vegan to recreate with similar ingredients to still get a fabulous result !

Hello. From Arizona USA. Just found you and love what I’ve been seeing. I haven’t tried anything yet but soon. First on the list is your “”No-Meat Ball w/tomato sauce” Still trying to make heads or tails of some of the different words you use. One question. How is this a flapjack. In the US that refers to a pancake..I’m calling it Yummy looking Desert!
