Lime, Courgette and Avocado Cake

Okay, hands up if you’ve ever looked at a courgette (or zucchini, my lovely American friends!) and thought, “you know what this needs? To be baked into a cake with an avocado and a squeeze of lime.” No? Me neither – at least not at first. But let me tell you, this lime, courgette and avocado cake is a revelation. Moist, zingy, lightly spiced, and surprisingly sweet… it’s the sort of bake that makes people say “wait – what’s in this?!” with a slightly suspicious but intrigued expression.

Whether you’re hunting for a courgette and avocado cake that just happens to be packed with nutrients, or you’re on the lookout for a gluten free courgette and avocado cake recipe that doesn’t taste like cardboard, you are in the right place.

Why Bake with Courgette and Avocado?

I know what you’re thinking. Why would anyone put a green vegetable and a fruit better known for toast into a cake? But bear with me. There’s some logic to the madness.

• Courgette (aka zucchini) is basically nature’s way of sneaking moisture into your bakes without adding loads of fat. It’s mild in flavour, and when grated finely, it disappears completely into the sponge. Think carrot cake – but greener.

• Avocado brings healthy fats to the party and creates a beautifully creamy texture. It also replaces butter or oil, which makes this cake a fab option if you’re dairy-free or just looking for a lighter alternative.

• Lime brightens everything up with a zesty kick that cuts through the richness.

Ingredients

This avocado and courgette cake recipe is surprisingly simple and very forgiving. You don’t need any fancy equipment – just a grater, a bowl and a spoon will do!

Here’s what you’ll need (UK and US measurements included):

Dry Ingredients:

• 200g (1 ½ cups) gluten-free self-raising flour (or plain flour + 1½ tsp GF baking powder)

• 100g (½ cup) soft brown sugar

• 1 tsp ground cinnamon

• ½ tsp ground nutmeg

• ½ tsp salt

• ½ tsp bicarbonate of soda (baking soda)

Wet Ingredients:

• 2 medium eggs (or flax eggs if vegan)

• 1 ripe avocado, mashed (about 120g / ½ cup)

• 150g (1 cup) grated courgette/zucchini (about 1 medium courgette)

• Zest and juice of 1 lime

• 60ml (¼ cup) maple syrup or honey

• 1 tsp vanilla extract

Optional add-ins:

• A handful of chopped pistachios or walnuts

• A few blueberries or raspberries tossed in a little flour

For the lime drizzle (optional but so worth it):

• Juice of 1 lime

• 2 tbsp icing sugar (powdered sugar)

Method

Ready to make some baking magic happen? Let’s go!

1. Preheat & Prep

Preheat your oven to 170°C (fan) / 180°C / 350°F. Grease and line a 1lb loaf tin or an 8” round cake tin – your choice. If you’re using a silicone loaf mould, a quick spray of oil will do.

2. Grate & Squeeze

Grate your courgette and place it in a clean tea towel. Give it a good squeeze over the sink to get rid of excess water. Nobody likes a soggy-bottomed bake.

3. Mix the Dry

In a large bowl, mix the flour, brown sugar, cinnamon, nutmeg, salt, and bicarbonate of soda. Set aside.

4. Mash & Mix the Wet

In another bowl, mash the avocado until smooth. Add in the eggs, lime zest and juice, maple syrup, and vanilla. Whisk until combined. Then stir in the grated courgette.

5. Combine & Pour

Gently fold the wet mix into the dry until just combined. Don’t overmix – a few lumps are totally fine. Fold in any extras like nuts or berries at this point.

6. Bake

Pour into your prepared tin and smooth the top. Bake for 40–50 minutes, or until a skewer comes out clean and the top is golden brown. (Top tip: if it starts browning too quickly, pop some foil on top for the last 10 mins.)

7. Cool & Drizzle

Let it cool in the tin for 10 mins before transferring to a wire rack. Mix up your lime drizzle and pour it over the warm cake for that extra citrus zing.

Why This Avocado and Courgette Cake Recipe Works So Well

I’ve baked a lot of healthy-ish cakes in my time (banana bread, I’m looking at you), but this one genuinely feels like a treat – not a compromise. It’s sweet but not sickly, dense but not heavy, and has a subtle spice that makes it feel like something you’d happily eat with a cup of tea or serve up at a fancy brunch.

Plus, this gluten free courgette and avocado cake recipe is a winner for people with dietary needs. Want it dairy-free? It already is. Need it vegan? Swap the eggs for flax eggs, and you’re sorted.

Ideas to Switch It Up

Feeling creative? You can totally tweak this avocado and courgette cake to make it your own:

• Make it chocolatey: Add 2 tbsp of cocoa powder and a handful of dark choc chips.

• Go tropical: Add shredded coconut and swap lime for lemon or orange.

• Add frosting: A simple cream cheese or whipped coconut frosting turns this into a proper showstopper.

Storing Your Cake

This cake keeps beautifully. In fact, I’d argue it gets better after a day or two. Store in an airtight container for up to 4 days, or freeze slices individually for future snacking. (You’ll thank yourself later.)

FAQs – Avocado and Courgette Cake

Can I freeze courgette and avocado cake?

Absolutely! Slice it up, wrap each slice in parchment, and pop in a freezer bag. It’ll keep for 2–3 months. Defrost at room temp or microwave in short bursts.

Do I need to peel the courgette first?

Nope! Just give it a wash and grate it with the skin on – it’s full of nutrients and disappears into the cake anyway.

Can I make this without eggs?

Yes! Use 2 flax eggs (2 tbsp ground flaxseed + 5 tbsp water, mixed and left to thicken) for a vegan version of this avocado and courgette cake recipe.

Is this cake sweet enough for kids?

Definitely. It’s sweet but not too sugary – and a great way to sneak in some extra veg and healthy fats. My 8-year-old had two slices before I told him what was in it (oops!).

What’s the best flour to use for a gluten free courgette and avocado cake?

I’ve had great results with a plain gluten-free flour blend plus baking powder, but self-raising GF flour also works well. If using almond flour, you may need to tweak quantities as it’s more dense.

Can I add a topping?

Go wild! Cream cheese frosting, coconut whipped cream, or just a dusting of icing sugar works a treat. Or keep it simple with the lime drizzle.

If you’ve never tried a courgette and avocado cake, this is your sign to give it a go. It’s one of those bakes that makes you feel a bit smug – like you’ve found a sneaky way to be healthy and indulgent at the same time. It’s also a great conversation starter (just wait until you reveal the ingredients after everyone’s had a bite!).

Whether you’re hunting for a gluten free courgette and avocado cake recipe or just want to shake up your usual banana bread routine, this is one to bookmark. Moist, zesty, easy to make, and packed with goodness – what more could you ask for in a cake?
