Instructions
1. Preheat oven to 180°C (160°C fan). Lightly grease and line two 18.5 cm round cake tins.
2. Whisk lemon juice into oat milk to create buttermilk. Set aside.
3. Cream margarine with both sugars using an electric whisk for about 3 minutes until light and fluffy.
4. Mix in the oat milk mixture, then fold in flour, spices, baking powder, baking soda, and dissolved coffee.
5. Divide batter between the tins. Bake for 25 minutes. Cool in tins for 5 minutes, then transfer to wire racks.
6. To make the coffee glaze: Heat coffee, water, and sugar in a saucepan, boil for 2 minutes while stirring. Remove from heat and stir in margarine and oat milk. Let cool.
7. To make the buttercream: Cream shortening and margarine. Gradually add sifted icing sugar. Add vanilla, oat milk, and salt. Stir in finely ground pistachios.
8. Toast chopped pistachios in a dry pan over medium heat for 3–4 minutes until lightly browned.
9. To assemble: Place one sponge layer on a plate. Spread with half the buttercream. Add the second layer. Top with remaining buttercream. Drizzle with glaze. Sprinkle with toasted pistachios.
