Add the sugar and salt to the sifted ingredients and whisk together to combine.
½ teaspoon (3 g) Salt, 1 ¼ Cup (250 g) Sugar
Add the eggs, oil, vanilla extract, almond extract and water to the dry ingredients.
4 (224 g) Eggs, ½ Cup (100 g) Oil, 1 teaspoon Vanilla, 1 teaspoon Almond Extract, ¾ Cup (187 ml) Water
Use a handheld mixer on low speed to combine the ingredients for 30 seconds.
If you want to use green food coloring, add 1 drop now. Then increase the mixer speed to medium and beat for 2 minutes.
Green Gel Food Coloring
Combine the cocoa powder and water in a small bowl. Whisk together until a chocolate sauce forms.
½ Cup (40 g) Unsweetened Cocoa Powder, 7 Tablespoons (110 ml) Water
Add 1 ½ cups of the pistachio cake batter to the chocolate sauce and mix until a chocolate cake batter forms.
Add ½ of the pistachio cake batter into your prepared cake pan, followed by ½ of the chocolate batter. Repeat with the remaining cake batter. Use a butter knife to swirl the two cake batters together (just a little). Tap the pan on the counter a few times to dislodge any air bubbles.
Bake in the preheated oven on the middle rack for 50 minutes or until the top of the cake springs back when gently poked.
Remove the cake from the oven and cool in the pan for 15 minutes. Then invert the cake onto a cooling rack to cool completely.
For the chocolate ganache
Place the chocolate chips into a heat proof bowl.
1 Cup Allergen Free Semi-Sweet Chocolate Chips
Heat the non-dairy cream in the microwave for about 1 minute. It should be warmer than body temperature. Pour the hot cream over the chocolate chips and let it sit for 5 minutes.
½ Cup Plant Based Cream
Use a whisk to combine the chocolate chips and cream into a smooth chocolate sauce. Add the corn syrup and whisk together until it's combined.
2 Tablespoons Corn Syrup
Pour the chocolate ganache over the cooled cake. Sprinkle the cake with chopped pistachios.
½ Cup Pistachios
Let the cake rest for about 30 minutes so the ganache can setup. You can speed this up by placing the whole cake in the refrigerator.
Notes
PISTACHIO FLOUR: If you don't have pistachio flour, you can grind your own by placing shelled pistachios in a food processor or high speed blender. Chop until it is fine powder then sift the nuts to remove any large pieces. Repeat until you have enough. CHOCOLATE SWIRL NOTE: You can replace the combined cocoa powder and water with ¾ cup of chocolate syrup if you prefer.STORAGE: Store in an airtight container at room temperature for up to 4 days.
