We don’t get to break out of our routine much these days. Luke is currently working every hour under the sun with his new job and I work from Thursday through to Sunday so if we’re not doing our own work thing then we are each running around after our non-stop toddler, accident prone dog and two crazy cats. Our house constantly looks trashed and the chores of laundry, washing up and tidying toys away are endless. We find it pretty exhausting just thinking about planning a break let alone organising one. When we do sit down together a hearty gin and tonic and an episode of Big Little Lies is about the only thing we’re capable of.

I find it hard taking time off, mainly because I don’t want to. I love working at the cake stall, baking cakes for my customers and if I ever have a free day then I relish recipe testing or writing the blog. Lately we have been realising though that our little family needed to actually spend time all together, to give the illusion of liking each other at least. So, a couple of weeks ago Luke had a little break in his schedule and we loaded up the car, arranged for cat sitters and hurried down to Cornwall for a few days.

The holiday may have been a Cornwall classic with long lazy walks on the beach in the beating down rain; plenty of Mr Whippy and fish and chips with seagulls circling ominously overheard. And of course Billy Buddy sanctioned a trip to a vet in Newquay as a must. Our dog is incapable of going a full week without some medical attention. This time it was merely another ear infection. However it was the break we needed and we have returned to the city afresh. We’re ready to take on June, which is pretty jam packed with toddler birthdays, including Cole’s who it turning 2 this month much to our disbelief.

Number one to-do on my return was to bake this Strawberry Sweet Pesto Cake. It’s not the first cake I’ve put basil in recently as I’ve been throwing it into my Blueberry, Basil and Lemon Drizzle Cake for years but I’ve really gone all in on it with this one.

The sweet pesto is just that, a verdant basil pesto without the garlic but with honey instead. It still retains pine nuts which go wonderfully with strawberries, olive oil for its peppery notes and even a small grating of parmesan for savoury undertones.

The cake is filled with a fresh strawberry basil jam which is quickly set with chia seeds instead of sugar. A teaspoon of freeze-dried strawberries stirred in is optional but I had them to hand for the strawberry buttercream so in they went. Freeze-dried berries are a brilliant way of injecting a pure intense fruity flavour and here it really amps up the jam. They are also invaluable in buttercreams as they mean you won’t lose any of the structural integrity of the buttercream like you would with a fresh strawberry puree or add any further sweetness if you were to use a strawberry jam.

The sponge is one of my go-to gluten-free recipes. It makes a rich moist and flavourful cake with my favourite combo of flours: sweet rice flour, oat flour, millet flour, potato starch and tapioca flour. It’s quite a little community of flours but this blend works so well and I’ll be posting a little bit more about different gluten-free flours and the jobs they do in our baking very soon, so please stay tuned for that.

Don’t get me wrong, going away is brilliant but I’m now really excited to be home with all this extra energy under my belt. I’ve got some great new cakes for the stall and the blog and I can’t wait to share them.

Instructions
Cake
  1. Preheat the oven to 160°C and line and grease 2 x round 8 inch cake tins.
  2. In a large bowl or food mixer whisk the lemon zest into the sugar until fragrant.
  3. Add the butter one cube at a time and beat into the lemon sugar until pale, light and fluffy.
  4. Add the eggs one at a time, beating on a low speed.
  5. Then mix in the vanilla extract.
  6. Whisk together the flours, baking powder and sea salt in a separate mixing bowl until completely combined.
  7. Add the flour mix alternately with the milk, adding the flour in three additions and the milk in two (begin and end with the flour), scrape down the sides of the bowls as needed and mix until just combined.
  8. Divide the batter between the cake tins and bake for 35-40 minutes when the sponge is coming away from the sides of the tin and an inserted cocktail stick comes out clean.
  9. Leave in the tins for 5 minutes to rest then gently turn out onto cooling racks and leave to cool completely.
Strawberry Basil Honey Jam
  1. Place everything but the chia seeds and strawberry powder in a pan and turn on the heat, crushing the strawberries gently with a wooden spoon into the rest of the ingredients.
  2. Bring the jam to a low boil, then simmer for a couple of minutes.
  3. Stir in the chia seeds and strawberry powder, cook for a further minute then remove from the heat and leave to cool.
Sweet Pesto
  1. Place everything in the food processor and whizz together until smooth.
Swiss Meringue Buttercream
  1. Heat egg whites and caster sugar in a bain marie, stirring constantly until the sugar has dissolved and the temperature has reached 71°C.
  2. Remove the egg whites and sugar from the heat and pour into a stand mixer with whisk attachment. Whisk until the mixture forms stiff peaks.
  3. Change the attachment to a paddle attachment. On a low speed add the butter slowly cube by cube. When you have almost added all the butter the mixture will look curdled. Do not fret – this is supposed to happen and just means you are nearly done. Just continue to add all the butter. Once the butter is totally incorporated the buttercream will miraculously become a smooth velvety consistency.
  4. Divide the buttercream so you have ¾ of the buttercream in one bowl and ¼ in another.
  5. Mix the strawberry powder with the ¾ amount of buttercream and the sweet pesto with the ¼ amount.
Assembly
  1. Place one of the cake layers on a cake board or stand.
  2. Pipe one circle of strawberry buttercream on the top at the very edge of the sponge. This will act as a dam for the strawberry jam.
  3. Spread the strawberry jam evenly on the top of sponge to the edges of the buttercream dam.
  4. Place the second sponge on top.
  5. Cover the strawberry buttercream over the top and the top half of the cake sides using a palette knife.
  6. Cover the bottom half of the sides with the sweet pesto buttercream. Use the palette knife to gentle blend the two flavours of buttercream together where they meet.
  7. Decorate the top of the cake with strawberries and basil leaves.
Recipe Notes

I am loving Nirvana Cakery’s beautiful blog at the moment and took inspiration for this Strawberry Sweet Pesto Cake from her stunning Raspberry Matcha Cake, using the same colour palette. I also adapted her raspberry jam filling into my Strawberry Basil Honey Jam.

SHOP THE RECIPE

Recently I have been using a lot of products from Realfoodsource.com and have been really happy with their service and quality of ingredients. I was excited when I found out they also stocked freeze-dried fruit powder and so for this recipe I really would recommend using RealFoodSource Certified Organic Freeze Dried Strawberry Powder 100G. I am not sponsored by them, I just really love their products.

The cake tins I always use are these PME Anodised Aluminium Round Cake Pan 8 x 4-Inch Deep which are wonderful as they have completely straight sides so your cakes will be beautifully neat, the anodised aluminium means the heat disperses evenly throughout the cake without cooking the sides too quickly, which some darker cake tins do. The cakes slip out of the tins easily and they come in all the sizes you would need, although typically I use the 8 inch tins.
