Step 1

Preheat oven to 350℉. Grease two 8-inch round cake pans with gluten-free nonstick cooking spray.

Step 2

Whisk together gluten-free flour, sugar, baking powder, and salt in a large bowl. Add oil, milk, eggs, and vanilla extract. Stir until smooth.

Step 3

Divide batter between the two prepared cake pans.

Step 4

Bake until a cake tester inserted into the center of the cake comes out clean, about 30 minutes.

Step 5

Allow cakes to cool in the pan for five minutes and then turn out onto a wire rack to cool completely.

Step 6

Prepare chocolate frosting. Mix butter for 30 seconds on high speed until light. Stop mixer. Add powdered sugar, cocoa powder, salt and milk. Mix, on low speed, until creamy. If frosting seems dry, add additional milk until smooth and creamy.

Step 7

Frost Cake. When cake is cool, fill and frost the cake.
