My four and a half year old has just discovered caramel. As such, everything has to be caramel flavoured and this Gluten-Free Caramel Cake was his special request. Gosh was it a good idea. We’ve now made it several times and we are refusing to get tired of it.
This caramel cake is so easy to whip up. Perfect for mini bakers to help out with but it also totally delivers on flavour and texture. It’s one of those everyday cakes that is suitable for any occasion. We have been snacking on it in between meals or with a scoop of peanut butter ice cream for dessert. Oh la, we have been spoilt.

Why you'll love this Gluten-Free Caramel Cake
- The multi-layered caramel flavour is achieved by using brown sugar, oat flour and teff flour.
- It’s not too sweet. Yes there’s tonnes of caramel taste but without the sickly sweetness.
- It takes no more than 15 minutes to mix up the sponge and 35 minutes in the oven. The icing takes 10 minutes. This is a quick cake to make.
- The icing develops a slight crunch on top which gives way to the creamy caramel. Such an amazing contrast to the sponge.
- There is no need to whip up your own caramel (although you are perfectly welcome to), instead use tinned Carnations Caramel or dulce de leche to make the icing super quick.
- You can serve this cake to a crowd or bring to a gathering as it makes lots of delicious little squares of cake.

Gluten-Free Flours
Along with the use of the brown sugar it’s the gluten-free flours which give the cake so much of its caramel flavour. Therefore I wouldn’t really recommend any substitutions here otherwise it would alter the taste of the cake.
- Oat Flour – The butterscotch flavour of the oat flour really brings out the caramel notes of the cake. It’s a light fluffy flour which gives a lovely texture too.
- Teff Flour – This is a lovely pairing with the oat flour, it accentuates the caramel taste whilst also giving its own earthy rich flavour.
- Sweet Rice Flour – This flour is integral to the structure of the cake. Its sticky tendencies keeps the cake together and gives it bounce. Plus its delicate flavour is not overwhelming.
How do you make Gluten-Free Caramel Cake?
- Cream brown sugar and unsalted butter until light and fluffy.
- Add the eggs one at a time, followed by the vanilla extract.
- Whisk up oat flour, teff flour, sweet rice flour, baking powder and salt then mix into the rest of the batter.
- Pour into a lined and greased 13x9 inch cake tin and bake for 35 minutes.
- Remove from the oven and cool before icing.
How do you make caramel icing?
- Warm butter and milk until just beginning to simmer.
- Remove from the heat and whisk in icing sugar, followed by caramel, vanilla extract and salt until smooth.
- Pour over the caramel sponge and leave to set for at least 2 hours.
Baker’s tips
- Make sure the butter is at room temperature before creaming with the sugar, so remove it from the fridge at least an hour before using (it also depends on how warm your kitchen is).
- Sift the brown sugar before using as it has a tendency to clump.
- Use medium eggs.
- Use a deep large rectangular cake tin.
- Test the cake to make sure it’s fully baked by inserting a cocktail stick, it should come out clean without any moist sponge clinging to it.
- You can use homemade caramel in the icing but tinned Carnations Caramel or dulce de leche is perfect here.
- Store this cake at room temperature in an airtight container. It will keep well for about 3 days before it starts to dry out. I use this rectangular cake container.
- You can freeze this cake with or without the icing, but wait until the cake has completely cooled and the icing totally set. It will keep for at least a couple of months in the freezer.

Variations to Gluten-Free Caramel Cake
- Dark Chocolate Chips! - The intensity of the bittersweet chocolate chips would contrast amazingly well with this caramel cake.
- Swap the caramel icing for a chocolate ganache. Stir together 200g chopped dark chocolate into 150g warm double cream with a pinch of salt until smooth then spread over the cooled caramel cake.
- Add some nuts. Stir in some chopped hazelnuts or pecans into the cake batter before pouring into the cake tin. You could also sprinkle them on top of the caramel.
- Caramel Apple Cake. Dice up some peeled granny smiths and stir through the cake batter before pouring into the cake tin.

Notes
Cake

- Sift the brown sugar before using as it has a tendency to clump.
- The eggs used in this recipe are medium size, 60g with shell and 50g without shell. If you can't get hold of medium eggs I suggest you weigh the amount.
- Test the cake to make sure it’s fully baked by inserting a cocktail stick, it should come out clean without any moist sponge clinging to it.
Icing
- I use Carnations Caramel but you can use dulce de leche or any thick caramel sauce.
- Icing recipe adapted from Handle The Heat’s Salted Caramel Apple Sheet Cake.

- You can freeze this cake with or without the icing, but wait until the cake has completely cooled and the icing totally set. It will keep for at least a couple of months in the freezer. Wrap up well in cling film and tin foil then let defrost overnight before unwrapping and icing.

Do you use a scale and weigh your ingredients? And do you have a conversion table for America weights and measures? Your recipes look delicious!!
Georgina Hartley says
Hi Nelda, yes I do weigh my ingredients - it's so important for gluten-free baking to achieve accurate results - especially as different brands of the same gluten-free flours can have vastly different volume amounts. That said, I have added the US Customary Measurements to this recipe - although do read the caveat in the notes section. Let me know if you try the recipe!
Lynn Matthews says
I made this the texture was like sand it just crumbled any ideas why?
Georgina Hartley says
Hi Lynn, that's not good. Please can I check that you used sweet rice flour rather than regular rice flour?
Juliana says
Hello Georgina!!
I have a question... What happens if I decrease the butter & sugar half the quantity? Should I decrease the flour as well? ... I wanna use my teff flour and I really like this recipe but I wanna make it a bit healthier for my diet... 🙂
Thank you so much 😀
Georgina Hartley says
Hi Juliana, this recipe wouldn't work if you were to decrease only the amount of butter and sugar. They are needed for the structure of the cake. You would have to decrease all the ingredients by the same amount - and then you are just getting the same cake but smaller. Sorry I can't be of more help for your query!!
Penny Vere says
I have a mouth full of dental fillings from eating my favorite treat, caramel when I was a kid. This is such a better option and really satisfies that caramel craving. Thanks for another great recipe Georgina!

You are very welcome!
