Gluten-Free Rhubarb Apple Coffee Cake that will knock your socks off. Incorporating rhubarb with apples into the body of this two-layer coffee cake with a subtle cinnamon essence.

The base of this gluten-free coffee cake is a buttery crumble topped with a light sponge cake filled with rhubarb and apples. When you combine the two layers, every bite is filled with so much deliciousness. This gluten-free cake is sooo good and moist, with rhubarb and apples throughout.

Why rhubarb and apples combination?

Rhubarb stalks taste like green apples, and when raw, they are very sour. Apples are sweet and go hand in hand with the tart rhubarb. When rhubarb is cooked, it tastes sweeter and makes for a delicious dessert.

did you know rhubarb is a vegetable?

Rhubarb is one of the earliest crops in the springs and is a vegetable. It looks similar to the celery, and the colours vary from crimson red, light pink or mostly green. The taste of the rhubarb is not usually affected by the colour.

The various colours make desserts look pretty. In this rhubarb apple coffee cake, I used red and pink colours…because they look pretty 🙂

Is rhubarb healthy?

Rhubarb is a low-calorie vegetable and is an excellent source of vitamin K. Half a cup of rhubarb provides more than one-third of recommended dietary intake of vitamin K.




This vegetable is also known for its powerful antioxidant properties and fiber. Add the apples to the mix, and this coffee cake has many health benefits.

I must confess this recipe originated in my grandmother’s kitchen, and I always have fond memories enjoying this cake. To make this coffee cake, I followed my grandmother’s recipe, except I made it gluten-free. The gluten-free rhubarb apple coffee cake turned out exactly the same as I remember it 😀
