Preheat the oven to 350F.
Take an 8’’ bundt cake mold, oil it, and dust it with flour. Place it into a baking tray and leave it aside.
Mix oil, ¾ cup of non-dairy milk, vanilla extract, granulated sugar, baking powder, salt, and orange juice in a large bowl.
1 1/4 cup sugar, 1 tsp vanilla extract, 1/2 cup vegetable oil, 3/4 cup non-dairy milk, 3 tsp baking powder, 1/4 tsp salt, 1/3 cup orange juice
Once it’s all well combined, add flour and stir until incorporated.
2 1/2 cup all purpose flour
Then, divide the cake batter into two bowls.
Add cacao powder and one tbsp of non-dairy milk to one of the bowls. Stir to combine
1/4 cup cacao powder, 1 tbsp non-dairy milk
Then add the orange zest to the other bowl. Stir each mixture until both are well combined.
1 tsp orange zest
Take the prepared mold, and pour some of the chocolate batter, followed by some of the orange batter. Repeat this process for the rest of the mixture. Once you finish, shake the mold to the sides to level the cake. Bake the cake for 45 to 50 minutes or until an inserted toothpick, comes out clean. Let the cake cool over the counter before unmolding.
Optional: dust some powdered sugar over the top of the cake before serving.
