Base and crumble topping:
190g rolled oats.
220g plain flour.
1/2 tsp baking powder.
Pinch of salt.
1/2 tsp ground cinnamon.
165g light brown sugar.
1 tsp vanilla extract.
2-3 medium sized cooking apples.
50g granulated sugar.
Small amount of water.
250ml Whole milk.
1 tsp Vanilla extract.
60g egg yolks.
50g caster sugar.
30g plain flour.
Before you get started on the recipe, you’ll want to start by doing some prep. Preheat your oven to 180˚c/350˚f, weigh up all of your ingredients and prepare any equipment you may need, such a large mixing bowl and spatula.
Before you get started on making the crumble or apple elements, you will want to make the creme pat layer which goes in the centre.
To start on the creme pat, simply take a pan and place in the milk, place on the hob. over a medium heat and allow to come almost to a boil. While you wait for that to come to a boil, in a operate bowl place the egg yolks and sugar, whisk them together until they are lighter and fluffier in colour and consistency. You can then add in the flour to the egg mixture, whisk until its fully incorporated into the mixture.
Once your egg mixture is done and the milk has come to a boil, simply pour around 1/3 of the milk into the egg mixture and whisk well until fully incorporated. This to help temper the temperature of the picture, if you add all of the hot milk straight in, you will more than likely scramble the mixture. So add your first 1/3 to temper the mixture, then you can go ahead and add the rest steadily as you continuously whisk the mixture.
Transfer the mintier into the pan and place back on the heat over a medium heat and continuously whisk this well, mostly as it will cook out the flour, thicken and happens very quickly. The last thing you want to happen is for it to catch on the bottom.
Now that the creme pat has formed and is thick, transfer into a bowl, covering with clingfilm touching the surface of the creme pat, so a skin doesn’t form. Allow cool fully before you use it.
The apple filling is super simple and tastes so much better than the stuff you can buy elsewhere. Simply peel, core and cut your apples into roughly equal sized pieces and add them into a pan with sugar and water, stir together, then place on the hob over a medium heat, allowing to cook for a little before interacting with the pan again.
The mixture should be broken down, so a apple sauce with chunks and apple still – not smooth at all! Allow to cool fully before you use it.
Start by melting together the butter, light brown sugar and vanilla extract (this can be done in a microwave or in a saucepan on the hob), while thats melting, combine the dry ingredients together in a large mixing bowl.
This is really simple but into the dry ingredients, pour the wet and mix until, fully incorporated. All of the oats should be coated in this mixture, they should have taken on a golden brown colour.
Now this is where you need to divide the mixture – into 1/3 and 2/3. The 2/3 is for the base of the apple bars and the other 1/3 is for the crumble topping.
Take a 9×9 inch square baking tin, line it with parchment and place in the 2/3 of crumble mixture, pressing down and spreading into a roughly equal layer. Bake in your preheated oven for 15 minutes
Then remove from the oven and top with the apple filling, spreading until as level as can be, topping that with the creme patisserie, again spreading out as level and possible. Now sprinkle over the 1/3 of the crumble mixture, giving even coverage, then place back into the oven and bake for a further 15-20 minutes (or until the filling is bubbling around the edge)..
Remove from the oven and cool fully before slicing up and enjoying. These can be enjoyed cold or slightly reheated for a more enjoyable crumble bar experience.
