This wholesome Apple Crumble Cake combines the warmth of cinnamon, the sweetness of apples, and the nutty crunch of almonds in the crumble topping.
We’re right on the cusp of shifting from winter to new season summer produce. Every year, I find it’s about now that the once crisp, bursting with flavour apples I’ve been buying are just not tasting so great. Some just don’t have the flavour, others are floury and not enjoyable to eat. But I never throw them, I just re-invent them like I’ve done here with this Apple Crumble Cake.
Truth is, once cooked and combined with other flavours they are quite delicious. If the apples are particularly floury, I’ll often mix them with a stronger flavoured fruit like rhubarb or berries of some kind and they are transformed. So like so many of my recipes, this soft buttery cake is a great base for experimenting with fruits and flavours.

Health Benefits
This Apple Crumble Cake recipe is not only a delicious treat but is also healthier than many apple cakes. Made with wholemeal spelt flour, it provides more fibre, vitamins, and minerals compared to refined flours, supporting digestive health and helping to stabilise blood sugar levels. The apples add natural sweetness and are rich in antioxidants and dietary fibre. Coconut sugar or rapadura, used as a sweetener, is less processed and has a lower glycemic index than refined sugars, making it a better choice for sustained energy. Additionally, the flaked almonds offer healthy fats, protein, and vitamin E, contributing to health and overall vitality.
Ingredients in this Apple Crumble Cake
The ingredients in this Apple Crumb Cake are thoughtfully chosen to create a balance of taste, texture and nutrition.
- Wholemeal spelt flour – Higher in fibre and nutrients compared to refined wheat flour.
- Melted Butter – Adds richness and moisture to the crumble and cake.
- Coconut sugar or rapadura – Natural, unrefined sweeteners with a lower glycemic index.
- Natural yoghurt (or plain greek yogurt) – Provides a tangy flavour, creamy texture, and beneficial probiotics.

- Fresh Granny Smith apples – Tart, fibre-rich, and full of antioxidants (you can also use other apples like gala apples or pink lady apples but I think Granny Smith taste best).

How to make this easy Apple Cake
To make this Apple Crumble Cake, start by preheating your oven and lining a slice tin with baking paper. Begin with the crumble by mixing the butter, sweetener, spelt flour, and cinnamon in a food processor or by hand until a heavy crumb forms. Fold in the flaked almonds and set the mixture aside. For the cake, mix the melted butter with yoghurt, sweetener, and egg until creamy and well combined. Add the cinnamon, baking powder, bicarbonate of soda, and sea salt, mixing thoroughly. Gently fold in the flour until just combined. Pour the cake batter into the prepared baking dish, spread the diced apple evenly over the top, and finish by sprinkling the streusel topping, pressing it down slightly. Bake for 35-40 minutes, or until a skewer inserted into the middle comes out clean.

Serving suggestions and how to store it

To store, allow the cake to cool to room temperature and then to chill fully in the fridge, which helps achieve clean, crumb-free slices. Once chilled, slice the cake and snap freeze the pieces on a tray before transferring them to an airtight container for longer storage. Alternatively, separate slices with baking paper and freeze airtight. This method ensures the cake stays fresh and easy to enjoy whenever you like.
