Ingredients:
For the Pistachio Cake:
- 250ml Milk (unsweetened almond milk or any plain milk of choice)
- 2 tsp White Vinegar
- 150g Granulated Sugar
- 80ml Oil (sunflower, canola, or vegetable oil)
- 2 tsp Vanilla Extract
- 220g All-Purpose Flour
- 30g Corn Starch
- 1 ½ tsp Baking Powder
- ¾ tsp Baking Soda
- 90g Pistachio flour (pistachio powder/ground pistachio) Note: To prepare homemade pistachio flour, use a food processor. Blend 90g of whole pistachios with 20g of granulated sugar until it forms a powder.
For the Chocolate Buttercream:
- 110g Butter (vegan butter sticks or regular butter)
- 40g Powdered Sugar
- 40g Dark Chocolate chips, melted
- 15ml Whipping Cream (for mixing with chocolate)
- Pinch of salt
Instructions:
Pistachio Cake:
- Preheat the oven to 350°F (175°C). Grease an 8x8-inch square cake tin and line it with baking paper.
- In a bowl, whisk together the flour, corn starch, baking powder, baking soda, and pistachio flour. Set aside.
- In another bowl, combine warm milk and vinegar. Allow it to sit for about 5 minutes until it slightly curdles. Add the oil, vanilla extract, and sugar to the milk mixture. Whisk until smooth.
- Gradually add the dry ingredients to the wet mixture, stirring until just combined.
- Pour the batter into the prepared tin and bake for 25-30 minutes or until a toothpick inserted comes out clean. Remove from oven and let it cool completely.
Chocolate Buttercream:
- In a stand mixer or using a hand mixer, cream together the butter and powdered sugar until light and fluffy.
- In a separate microwave-safe bowl, combine chocolate chips with whipping cream. Microwave for 30 seconds and stir to ensure it's smoothly combined. Allow it to cool.
- Slowly blend the cooled chocolate mixture into the butter mixture. Continue mixing for 2-3 minutes until fully incorporated.
To Assemble:
- Once the cake has cooled, evenly spread the chocolate buttercream over the top.
- Chill the frosted cake in the refrigerator for at least 1 hour before serving.
- Garnish with chopped pistachios before serving.
Enjoy this delightful combination of nutty pistachio and rich chocolate!
