Step one

Cake: Preheat oven to 350˚F (180°C). Grease and flour two 9-inch (23 cm) round cake pans (or line bottom of each pan with parchment paper).
Step two

In small bowl, combine coconut milk, buttermilk, milk and chia seeds; stir in mint extract and food colouring. In separate large bowl, beat together cake mix and shortening; beat in milk mixture for about 2 minutes or until well combined, scraping down side as needed.
Step three

Divide batter evenly between pans. Bake for 25 to 30 minutes or until tester comes out clean when inserted into center; let cool completely on rack.
Step four

Frosting: Using electric mixer, beat butter until light and fluffy. With mixer on low speed, beat in icing sugar, buttermilk and vanilla until blended and smooth (if needed, add 1 to 2 tbsp/15 to 30 mL more buttermilk). Increase speed to high; beat for 1 to 2 minutes or until light and fluffy.
Step five

Place one cake layer on serving platter; spread generous 1/2 cup (125 mL) frosting over top. Top with remaining cake layer; spread remaining frosting over top and side of cake.
Step six

Refrigerate for at least 1 hour before serving. Garnish with chocolate shavings (if using).
