A small cake can still feel like a proper celebration. This pistachio raspberry cake uses two 6-inch layers, a thin ribbon of raspberry jam and a relaxed cream cheese finish. The muted pistachio crumb and bright berries provide the colour; there is no food colouring or elaborate piping. The method explains how finely to grind the nuts, how much filling to add and how to leave a little sponge visible through the sides. This is an original recipe draft that has not yet been kitchen-tested; use the texture and doneness cues alongside the estimated timings.

A little preparation

Before you start

  • Two 6-inch / 15-cm round cake pans, at least 2 inches / 5 cm deep
  • Parchment, kitchen scale and cooling rack
  • Food processor or nut grinder
  • Electric hand mixer or stand mixer
  • Spatula, small offset palette knife or butter knife
  • A plate or cake board that fits in the refrigerator
01

A two-layer cake for a small gathering

These quantities are for two 6-inch pans, not two 8-inch pans. A larger pan spreads the batter more thinly and changes the bake. Divide the batter evenly so both layers finish at a similar time and the final cake does not lean.

The intended finish is semi-naked: a thin layer of frosting covers the sides with some sponge still visible. That keeps the decorating approachable and gives the chopped pistachios and raspberries on top a clear place to stand out.

02

Ground pistachios give flavour without pudding mix

Choose shelled, unsalted pistachios and check them for any hard pieces of shell. Pulse them with a spoonful taken from the measured flour until they resemble a fine, slightly uneven meal. Stop before the oils turn the mixture into a paste.

Natural pistachio cake is usually muted green-beige rather than bright green. Nut variety, skins and roasting all affect its colour. The recipe uses pistachios themselves, so pudding mix or sweetened pistachio cream cannot replace them without changing the formula.

03

Keep the raspberry filling in a thin layer

Use thick raspberry jam for the filling. Fresh berries release moisture and create larger gaps between layers, so they are reserved for the top. Spread frosting over the first cake and leave a slightly thicker rim around its edge; a spoon can make this border without a piping bag.

Add the jam inside the rim and keep it away from the outer edge. More jam is not automatically better: too much makes the upper layer slide. Place the second layer on gently and chill the assembled cake if the frosting starts to soften.

04

A spoon finish and a crescent of colour

Spread a thin coat of frosting over the sides, then draw the palette knife around them once or twice. Do not keep scraping until the cake looks perfectly smooth; a little texture suits this finish. Add the remaining frosting to the top and make shallow spoon swirls.

Arrange the dry raspberries and chopped pistachios in a loose crescent rather than covering the whole top. This leaves a calm area of ivory frosting and makes every colour readable. Add the fresh berries close to serving.

05

Make ahead, chill and slice

Bake the two layers a day ahead, cool fully, wrap and refrigerate. Cold layers are easier to assemble. Once filled and frosted, keep the cake covered in the refrigerator and use within 3 days, with fresh raspberries added on the serving day.

Chill the assembled cake for around 30 minutes before cutting so the filling has support. Wipe the knife between slices. Let individual slices stand briefly before serving; cold butter-based sponge and frosting will feel firmer straight from the refrigerator.

Filling and finish

Let’s make it

  1. Heat the oven to 175°C / 350°F conventional, or 155°C fan. Grease two 6-inch round pans and line the bases with parchment.
  2. If starting with whole pistachios, pulse the 70 g nuts with a spoonful of the measured flour until a fine meal forms. Stop before it becomes a paste. Whisk with the remaining flour, baking powder and salt.
  3. Beat the softened cake butter and sugar for about 3 minutes until lighter. Beat in the eggs one at a time, scraping the bowl, then add the vanilla. Stir the yogurt and milk together in a jug.
  4. On low speed, add the dry mixture in three additions, alternating with the yogurt mixture in two additions. Stop as soon as combined and scrape the bottom of the bowl with a spatula. Divide evenly between the prepared pans.
  5. Bake for approximately 25 to 32 minutes. Check from 25 minutes: the tops should spring back gently and a skewer should show a few moist crumbs but no wet batter. Cool in the pans for 10 minutes, then turn out onto a rack and cool completely.
  6. Make the frosting. Beat the 100 g frosting butter until smooth, gradually mix in the icing sugar and salt, then add the cool cream cheese and vanilla. Mix briefly on low speed just until smooth. If loose, chill for 15 to 20 minutes before using.
  7. Set one cold cake layer on a plate. Spread roughly 100 g frosting over it, leaving the outer rim slightly thicker. Spoon the jam inside that rim, keeping it away from the edge. Add the second layer and press very gently to level.
  8. Spread a thin coat of frosting around the sides so some crumb remains visible. Add the remaining frosting to the top and make shallow spoon swirls. Chill the assembled cake for about 30 minutes to support the filling.
  9. Before serving, arrange the dry raspberries and chopped pistachios in a crescent across the top. Cut into eight modest slices and keep leftovers covered in the refrigerator.

From the notebook

The little details

  • Grind the pistachios with a little of the recipe flour and stop before they become oily.
  • Spread the jam inside the frosting rim rather than all the way to the edge.
  • Keep the natural muted cake colour; the raspberries provide the bright contrast.

Your questions, answered

Is this a 6-inch or 8-inch cake recipe?

It is written for two 6-inch round pans. Two 8-inch pans would make thinner layers and would need a different baking assessment.

Can I use pistachio pudding mix?

No direct substitution is provided. Pudding mix contains starch, sugar and flavourings, while this formula uses ground nuts.

Do I need to pipe a frosting border?

No. Spread the filling frosting with a spoon, leaving a slightly thicker rim around the edge to contain the jam.

Why is my pistachio cake not bright green?

Ground pistachios naturally give a muted green-beige crumb. Nut skins and roasting affect the shade. This version does not use green food colouring.
