Mango Oatmeal Crumble Bars Recipe!

Hello lovelies,

One fruit I have been absolutely loving recently is mango. Ive been having it in my smoothies and boy is it good. I’m slightly obsessed, that being said, I’ve never actually baked with it. Disappointing, I know!

So that of course had to change asap! Me being me, I went onto Pinterest to search for inspiration (as I wasn’t 100% sure what I could do with a mango being that I’ve never used it before) and I came across these mango crumble bars. How damn good does that sound?

Therefore, I can’t take credit for todays bake. It was completely inspired by this recipe: – it captured my attention straight away and I just knew I had to give it a go myself.

I’ve fallen well and truly in love with baking crumbles in bar form and the thought of adding mango into the recipe is just *chefs kiss*. Guys, don’t sleep on these bars! If you are a mango loving kinda person, these will be right up your street. I’ve got no other words than: just divine.

So if you’d like to get making these bars yourself, tie your aprons up, get your ingredients ready and let’s get our bake on…

Category: Sweet Treat

Serves: 12

Prep Time: 15 Minutes

Cook Time: 50 Minutes

Overall Time: 1Hour 10Minutes

Ingredients You Need For Crust & Crumble Topping:

  • 113g Of Unsalted Butter
  • 120g Of Plain Flour
  • 96g Of Oats
  • 100g of Granulated Sugar
  • 50g Of Light Brown Sugar

Ingredients You Need For Filling:

  • 1 Fresh Mango, Diced Or Frozen Mango Chunks, Defrosted & Diced
  • 75g Of Granulated Sugar
  • 2tbsp Of Lemon Juice
  • 2tbsp Of Corn Starch

How To Make Crust & Crumble:

  • Firstly, gather together your equipment and ingredients, line a 9inch square tin with parchment paper and preheat the oven to 200C / 180C Fan / Gas Mark 5.
  • Secondly, in a large microwavable bowl place 113g of unsalted butter and in 30 second blasts, blast the butter until its completed melted.
  • Once melted, place the melted butter into a large bowl alongside the 120g of plain flour, 96g of oats, 100g of granulated sugar and 50g of light brown sugar and stir to combine (TIP: the mixture will be dry and sandy with some large, well-formed crumble pieces).
  • Now, place half of the crumble mixture into the prepared lined tin and using a spatula, press the mixture into the bottom of the tin until evenly spread and smooth. Set the other half of the crumble mixture to the side.

How To Make Filling:

  • In a large mixing bowl, add the 1 diced mango, 75g of granulated sugar, 2tbsp of lemon juice and 2tbsp of corn starch and mix together to combine.
  • Now, evenly distribute the mango mixture across the crust.
  • Then, sprinkle the remaining crumble which you’d set aside over the top of the mango filling.
  • Next, place the crumble bars into the oven for around 50 minutes, until the crumble is golden brown and the edges and centre of the bars have set.
  • Finally, take out the oven and allow the bars to cool slightly in the tin before removing from the tin and transferring onto a wire rack to cool down completely.

That’s your Mango Oatmeal Crumble Bars prepared, baked and ready for you to demolish.

I just knew I had to share these with you guys as soon as my family took the first bite. It was ‘umming and arring’ (all the sounds you want to hear) all round and it’s easily become a favourite in this household.

Can we also just take a moment to appreciate how damn easy these bars are to make. It literally takes no longer than 15 minutes to create these bars (excluding oven time ofc) and there’s no hardship about it. It’s quick, easy and the outcome is absolutely delicious. Need I say more.

Let me know in the comments below if you make these bars yourself and if you do, what your thoughts are on them. Are you a crumble in bar form kinda person? Has this changed the game for you when cooking with mango?

Sending you all tons of love & hugs as always,

Elle xo
