all ingredients for apple sour cream slice, laid out on a table.

Plain flour – plain (all-purpose) flour forms the shortbread crust. Be sure to weigh the flour for the perfect base. Too much or too little flour can alter the texture or cause it to crumble. Weights have been included below, for accuracy.
Rice flour – mixes with the plain flour to make the perfect, crisp and golden shortbread base for the slice. Cornflour can be used instead, but I recommend rice flour for best results.
Icing sugar – also called confectioners’ sugar or powdered sugar, icing sugar adds sweetness and texture to the shortbread crust. This slice is not overly sweet, so it’s important to use the exact amount of icing sugar.
Butter – helps to bind the shortbread base. It needs to be chilled, straight from the fridge to form a perfect, flaky and tender crust. I recommend using real, salted or unsalted butter rather than margarine or butter substitutes, for best results.
Canned pie apples – are used for the apple layer. Canned pie apples are pre-stewed with no added sugars and are ready to use straight from the can, making them a quick and convenient option. They can be found in supermarkets in the canned fruit section. Of course, you can also use homemade pie apples or stewed apples if you have an excess of apples on hand. Just be sure to drain any excess liquid before adding them to the slice, or the slice will be overly wet.
Sour cream – for the topping layer. Use regular, full fat sour cream for best results. Light or low-fat sour cream won’t set as firmly.
Cinnamon – ground cinnamon is used to flavour the apple filling. And it’s also used to make cinnamon sugar, which is sprinkled over the sour cream layer before baking.

Expert tips

Line the baking tin. Lining the tin with baking/parchment paper makes it easier to remove the slice from the pan. Leave the edges of the paper long, to help lift the slice from the tin when it has fully set. The base is more fragile when warm, so if you want to eat it right away, cut the slice while still in the tin and remove individual pieces one at a time.
Use chilled butter straight from the fridge to make the shortbread. As with making pie dough, cold butter will produce a more tender crust. Use a food processor where possible, to speed up the process and avoid warming the dough with your hands.
If you don’t have a food processor, rub the butter into the flour with your fingertips and mix until a soft dough forms. Try to keep the butter and dough as cool as possible.
Instead of apples, you can swap for canned pears, or even peaches or apricots.
This slice is not overly sweet. There is no added sugar in the pie apples and only a sprinkle of cinnamon sugar on the sour cream layer. If you prefer the slice a little sweeter, mix 2-3 tablespoons of caster sugar into the apple layer or through the sour cream before layering it onto the slice.
Drain the apples first, to ensure there isn’t a lot of liquid, or the slice will be wet.
The slice should chill for at least 2-3 hours before slicing, to firm up completely. Serve it chilled – it tastes even better after a day or two in the fridge!

FAQs

Can you freeze apple sour cream slice?

I have tested this slice and the freezer and found that it does not freeze well. The sour cream layer tends to become grainy and overall, the slice loses some of its texture. It is not suitable for freezing. I recommend making it on the day (or day before) you want to serve it, and store it in the fridge.

How to store it;

Keep the slice chilled in the fridge in an airtight container for 4-5 days.
