Gluten-free vanilla loaf cake recipe: Frequently Asked Questions

Can I make this recipe gluten-free? Is it suitable for Coeliacs?

It is gluten-free, though nobody would know just by tasting it – trust me!

Bear in mind that minimising cross-contamination is hugely important if you’re Coeliac or making this for someone who is. Here’s some tips from Coeliac UK on minimising the risk of cross contamination:

Also, make sure that all ingredients used don’t have any gluten-containing ingredients. Then make that that they also don’t have a ‘may contain’ warning for gluten, wheat, rye, barley, oats (which aren’t gf), spelt and khorasan wheat (aka Kamut).

Here’s some more info from Coeliac UK on identifying safe gluten-free products.

Can I make your gluten-free vanilla loaf cake recipe dairy free?

Yep – you can easily make this dairy-free with a couple of simple swaps.

For the sponge cake, all you need to use is a softened block of hard margarine or a dairy free margarine spread like this, instead of butter.
Whilst you can use a dairy free margarine spread for the cake, DO NOT use it for the buttercream. It’s far too soft and won’t hold like buttercream should. Use the hard block of margarine instead for that – you may need to add a little more icing sugar to bring it together as hard margarine is softer than butter.

Can I make your gluten-free vanilla loaf cake recipe vegan?

Yep! If you follow the instructions above to make this recipe dairy free, then all you’ve got left to contend with is the eggs.

Here’s a few ideas you can use as egg replacements, so each of these = 1 egg.

3 tablespoons of aquafaba (whisked until frothy) – water from a can of chickpeas. Keep the chickpeas for a future dinner!
1 tbsp of ground flaxseed and 3 tbsp of water
Egg replacement powder – I’d recommend using Orgran as it’s gluten free.
1 tablespoon of chia/flax seeds mixed with 2 tablespoons of water and left for 10 minutes in the fridge.
3 tablespoons of applesauce.

I haven’t tested all of these egg alternatives so let me know how you get on in the comments below.

Can I make this recipe low FODMAP?

Yes! One slice of this cake is low FODMAP and suitable for the elimination phase of the diet assuming your sprinkles don’t contain any high FODMAP ingredients.

Is your gluten-free vanilla loaf cake recipe nut-free?

Yep, this is a nut-free recipe as far as ingredients go, BUT make sure you check the ingredients label on ALL the products you use to bake this cake just to be safe.

Even if the products don’t contain nuts, they may have a ‘may contain nuts’ warning due to being produced in a factory that handles nuts.

You can never be too careful so always read the labels on everything first!

Which sprinkles did you use?

I used the Shire Bakery’s bake-stable funfetti sprinkles – they just have that little extra wow factor that you can’t find in the sprinkles in supermarkets.

As they’re bake-stable, you can even mix them into your cake mixture too and they won’t melt. Your sponge will be filled with tons of little flecks of colour and be generally awesome.

Plus, they’re gluten-free too! Not all sprinkles are, so make sure you double-check whichever ones you’re using.

Can I make this using the creaming method?

Of course – I prefer to use the all-in-one method for these as I find it’s always a safe bet with a simple sponge like this.

But of course, you’re more than welcome to cream the sugar and softened butter together, then add the eggs and mix, THEN add the flour and mix once more.

It works perfect both ways so it’s totally up to you!

Can I make your gluten-free vanilla loaf cake in a food processor or standing mixer?

Of course you can – and it’ll save you on elbow grease! I don’t use a standing mixer or food processor to make the cake mixture personally – I use an electric whisk.

For the buttercream, I always prefer to make it in my stand mixer, purely because of the amount of mixing it takes to beat the butter until it becomes pale/mixing in the icing sugar.

Can I make your gluten-free vanilla loaf cake recipe by hand?

You can of course, bake this without any assistance from any appliance – just a good ol’ fashioned silicone spatula will do. Just make sure you give it a lot of welly, otherwise your mixture won’t be consistent and might not bake properly.

Making the buttercream by hand is definitely possible, but it’ll take longer and requires a little more effort. But it’s definitely doable!

Do I need any special equipment to bake your gluten-free vanilla loaf cake recipe?

Certainly not! You will need a good quality 2lb loaf tin though, so here’s a link to the one I use.

Does this recipe need xanthan gum?

In some of my recipes, yes, but I wouldn’t recommend leaving xanthan gum out of this one. You’ll see xanthan gum in a lot of my recipes as it’s an essential ingredient in gluten-free baking.

Without gluten to bind the cake batter together, you can be left with a very loose and crumbly sponge texture which won’t work for this recipe.

Some people have asked if they can use psyllium husk powder instead of xanthan gum, but I’ve found that it definitely results in a denser sponge so I wouldn’t overly recommend it.

If you’re really against xanthan gum or you simply don’t have any, you can omit it if pushed. There’s a little in gluten-free self-raising flour anyway, so this bake should still turn out fine.

Can I make this recipe using other gluten-free flours like buckwheat flour or coconut flour?

There’s a big difference between ‘gluten-free plain/self-raising flour’ and a *singular* type gluten-free flour. When I say ‘gluten-free plain or self-raising flour’ in a recipe, I mean a BLEND of gluten-free flours, not just one, singular flour.

Most gluten-free flour you buy in the supermarket typically contains a blend of rice flour, potato flour, maize flour, tapioca flour AND buckwheat flour. That’s a lot of different flours!

In gluten-free self-raising flour, there’s usually even a little baking powder and xanthan gum in it too which always helps. So to replace it with just one specific type of flour… that’s not going to cut it at all. Definitely go for a gluten-free flour blend.

Do I need weighing scales to bake your gluten-free vanilla loaf cake recipe?

In short… yes, yes and yes! And I wouldn’t advise attempting any my recipes without them.

A lot of work went into fine tuning ratios and quantities and for me, baking is all about consistency and precision. I want you to make this recipe and for it to turn out EXACTLY like mine did.

I’d recommending using digital cooking scales like these so you know you’re getting an accurate measurement and replicating my recipe as accurately as poss.

Can I bake your gluten-free vanilla loaf cake recipe with less sugar / without sugar?

I can definitely understand the need to reduce sugar in our foods, but this is one of the recipes where I wouldn’t advise it.

Of course, the sugar isn’t just for sweetness – it’s integral to the structure of the cake once baked and is super important.

The more you reduce the sugar in the sponge, the more dry and ‘mealy’ the cake will become.

You can of course reduce the buttercream if you’re concerned about sugar – it’s up to you.

How long can I keep your gluten-free vanilla loaf cake for?

I’ve kept it for about 4-5 days in an air-tight container with no problems. If you need it any longer than that, I’d highly recommend freezing it (see advice below for doing that)

When the cake starts getting a little dry, it’s probably starting to get past its best.

Can I freeze your gluten-free vanilla loaf cake?

Of course! I’ve frozen it for up to 2-3 months no problem. Ideally, slice up the cake first before freezing – that way you can simply defrost slices as and when you need them.

Plus, it’ll thaw a lot quicker. When you want to eat it, each slice should take around 3 hours to defrost at room temperature.

How can I tell when my gluten-free vanilla loaf cake is done?

Grab a skewer and give it a poke in the centre. If it comes out clean, then it’s done!

But if the skewer comes out moist and cake-like, it’s best to pop it back in for a bit longer.
