This delicious apple slice is the ultimate comfort food. It has a buttery sweet shortcrust base, a lush apple and cinnamon filling and is topped with a crispy, German-style brown sugar streusel topping. Thermomix and food processor recipe included.
This recipe has been a family favourite for a long time. I first started making the slice before I had my Thermomix so the recipe includes instructions for making this in the food processor or TM.
I've mentioned before that I'm a very lazy cook. I'm reminding you now because although this is technically a three-layer slice it is so easy that you just have to make it! The layers are simply added one after another and then the sliced is baked off for 45 minutes.
Serve the apple slice straight out of the oven with custard and ice cream for a lovely warming dessert or refrigerate and serve cold for morning tea. This is a very versatile sweet! Regardless of whether you eat it hot or cold, I'm sure it will become a firm favourite.
Apple Streusel Slice Substitute Ingredients
One of the things I love most about this recipe is that the ingredients are usually in my pantry ready for a craving to strike.
Salted Butter
I use salted butter because it gives just the right amount of saltiness against the sweet ingredients. If you only have unsalted butter you can substitute this but please add a pinch to ¼ of a teaspoon of salt.
Green Apples
Green apples are more start than red and tend to hold their shape a little better. If you have some red apples that need using you can swap them for the green apples but maybe add a tiny bit more lemon vest to cut through the sweetness.
Lemon Juice & Zest
Sorry, there is no substitute ingredient for this. You can leave it out but the slice will be a bit sweeter.
The remainder of the ingredients should be fairly straightforward, but feel free to ask if you have any questions.
Frequently Asked Apple Slice Questions
I have used White Wings Gluten Free flour with a little more butter. The results were good although the slice wasn't as firm as regular flour.
The slice will be soft when it first comes out of the oven. It will cool and become firmer.
Place the slice in an airtight container and store it in the fridge,
The slice can be kept for a week in the fridge.

could you leave the egg out of the pastry for an egg allergy? would you just add a bit of water instead for the liquid?
Julie Carlyle says
Hi Sharon
Thank you for your question. The egg does help bind the pastry and enable it to hold together when it is cut. I haven't tried it without an egg but you can always give it a go and let me know what happens, it may just work 🙂
Happy Cooking

Sarah says
This was a hit! So easy to make, and super delicious. I had a heap of apples to use up and was searching for recipes when I came across yours. I didn't have any apple sauce, but used two grated apples to fill in the gaps between the apple chunks and it worked perfectly. Thanks for the delicious recipe!
india says
hi is it possible to do this recipe without a food processor? thanks!
Julie Carlyle says
Hi India, Yes it's possible. You will just need to rub the flour and butter together as you do for a scone recipe and then mix through the remaining base ingredients.

Hi Cathy, I am so pleased you liked it and the recipe was well received at the office 🙂 I love hearing comments like yours, it inspires me to make more recipes 🙂

I made this today and I had to let you know that it's the nicest apple slice I've ever made!
The recipe worked exactly as stated and I didn't make too much of a mess when I cut it into squares either, even though it was still quite warm (couldn't wait for it to chill) 🙂
So melt in the mouth. Thank you for such a lovely recipe.
