Add your other 4 ingredients and mix until well combined.

I am using gluten-free rolled oats but you could use porridge oats too.

Don’t have all these ingredients, here are a few swaps for you:

Maple Syrup – swap for honey or agave syrup.

Gluten Free Rolled Oats – Use porridge oats instead or non gluten free if ok for you.

Cacao powder – leave it out and just use chocolate chips.

Chocolate – just leave it out.

If you have kids, this recipe is perfect for them to get stuck in and bake something delicious.

They will totally love making the mix and eating them at the end of course!

Flapjack mix

Once you have formed your homemade flapjack mixture simply push into a lined square baking tin. I use this 9×9 baking tin

Once baked they come out the oven smelling incredible.

You will want to dig in straight away of course but you NEED to let it cool for 10 minutes outside of the baking tin. 

This helps the flapjacks to firm up a little and helps with slicing into squares.

You will still get to eat them nice and warm which is how I prefer them.

  1. 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 !
    So simple to make I have shared the recipe with my daughter for my grandchildren to make

  2. Made these for the first time today, so quick and easy, I didn’t have maple syrup so used local honey and it worked well

  3. Another delicious recipes.It was quick to make and my 10 year old son made these flapjack with limited supervision. Happy that my son can enjoy a healthy treat every week.

  4. Fast&easy! More importantly, it tastes amazing and matches the recipes/pics. Add more cacao powder for extra gooey goodness!

  6. Our second batch is in the oven right now. I made them last week and my daughters have been talking about them ever since. They really are delicious! Thanks for the recipe!

  7. Oh my this is heaven! I have a sugar and gluten intolerance and find it hard to find really yummy treats but this one takes the cake! I sometimes warm it up just slightly in the microwave before eatting and it’s to die for. Thank you so much definitely a new regular

  8. 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!
