1/2 cup canola oil
2 eggs
1/2 cup sugar
1 teaspoon vanilla
2/3 cup milk or buttermilk
1-3/4 cups flour
1 teaspoon baking powder
3 tablespoons cocoa powder

Combine canola oil, eggs, sugar and vanilla and mix until fully combined. Stir in the flour and baking powder. Pour 1/3 of the batter into a separate bowl and mix in the cocoa powder. Alternate pouring large spoonfuls of each batter into a greased cake pan. Swirl the batter with a knife just until it looks like the marble pattern. Bake at 350 for 30-35 minutes.

2 tablespoons butter, melted
1 teaspoon instant coffee powder
2 tablespoons milk
2 cups confectioners sugar

Mix the butter, milk and coffee powder until the coffee powder is fully dissolved. Add in the confectioners sugar. You may need to add more sugar if the frosting is too runny or more milk if it is too thick. Frost the cake after it has had ample time to cool.
