To a large mixing bowl, add the oil, sugar, coconut milk, vanilla extract, lemon extract, lemon juice, lemon zest, and eggs. Whisk together until everything is completely incorporated.
Add the dry ingredients
Now add the flour, baking powder, baking soda, and salt. Whisk until the dry ingredients are completely incorporated, taking care not to over mix.
Bake the cake
Preheat the oven to 350 degrees.
Grease a 9x13 inch glass baking dish with cooking spray.
Pour the cake batter evenly into the pan, then shake the pan gently a few times to let air bubbles in the batter rise to the top.
Bake the cake at 350 degrees for 30 minutes, until the top is firmly set and a toothpick inserted in the middle comes out clean.
Make the icing
While the cake cools, make the icing.
In a small mixing bowl, stir together the (just melted) butter, lemon juice, lemon zest, and lemon extract.
Now add ¾ cup of the powdered sugar. Mix the powdered sugar in until smooth, then add the remaining 1 cup of powdered sugar. The icing will be very thick and a little lumpy.
Now add the 2 tsp of almond milk, and stir until completely incorporated. The icing will be thick and smooth.
Ice the cake
Let the cake cool for 15 minutes before icing.
After the cake has cooled for 15 minutes, pour the icing over the cake.
Use an offset spatula to help spread the icing completely over the cake. The icing will cover the top of the cake, and make its way down the edges as well.
Let the iced cake cook for at least 45 minutes before slicing. This allows the cake to absorb the icing, and gives the icing time to set on top.
Serve and think of Doris!
Serve this cake alone, with a glass of almond milk, or with vanilla ice cream, and think of Doris.
Notes
This is a very lemony lemon cake. If you're not a fan of strong lemon flavor, this may not be the cake for you. Alternately, you could try cutting back on the lemon extract by a tsp or two.If you don't have lemon extract on hand, here's my favorite on Amazon [aff. link].Use an offset spatula to make icing the cake easy.
