Crank up your oven to 160C (fan)/180C (regular)/355F. Prep two 20cm round cake pans—grease them up and line the bases with non-stick paper, then set them aside.

Pop the butter and sugar into a big bowl. Grab a hand mixer or a stand mixer with the paddle attachment and whip the mixture for 3–5 minutes until it's super light, smooth, and fluffy. Stir in the vanilla and give it another mix.

One by one, crack in the eggs and whisk each time until your batter becomes smooth as silk.

Carefully sift in the flour and baking powder, then toss in the salt and ground pistachios. Gently fold until everything's just brought together—don’t overdo it!

Scoop the batter into your prepared tins, smoothing out the tops with a spatula or back of a spoon. Bake for 35 minutes or so, until a toothpick poked in the center comes out clean and they're nicely risen.

Take your cakes out of the oven and let them chill in their tins for 15 minutes. Then flip them onto a wire rack to cool completely. (If the green tones fade on the edges, don't worry—the inside will still pop!)

While the sponge cools, whip up the buttercream. Beat the softened butter and sifted icing sugar with a mixer until it's creamy and pale. Add in the lemon juice, pistachio cream, and salt, then mix again. Adjust lemon to taste.

When the cakes are fully cool, place one on a serving plate. Pipe half the buttercream on top in an even layer. Carefully spread the jam over the buttercream, steering clear of the edges. Pop the second cake on top and smooth the rest of the buttercream over the top layer.

Scatter fresh raspberries, chopped pistachios, and some mint leaves over the top for a pretty finish. Time to dig in!
