Soy flour, derived from soybeans, is a versatile gluten-free flour that offers numerous nutritional benefits. Its high protein and fiber content makes it an excellent choice for individuals seeking a nutritious and delicious cake. This article provides a step-by-step guide to crafting a delectable cake using soy flour at home, along with essential tips and additional information.


For the Cake:

  • 1 1/2 cups soy flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 cup unsweetened cocoa powder
  • 2 cups granulated sugar
  • 1 cup buttermilk (or 1 cup milk + 1 tablespoon lemon juice)
  • 1/2 cup vegetable oil
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1 cup boiling water

For the Frosting:

  • 1 cup soy milk (or regular milk)
  • 1/2 cup soy butter (or regular butter)
  • 1/2 cup cocoa powder
  • 3 cups powdered sugar
  • 1/2 teaspoon vanilla extract


Step 1: Prepare the Cake Batter

  • Preheat oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan.
  • In a large bowl, whisk together soy flour, baking soda, salt, and cocoa powder.
  • In a separate bowl, combine granulated sugar, buttermilk, vegetable oil, eggs, and vanilla extract.
  • Gradually pour the wet ingredients into the dry ingredients, mixing until just combined. Do not overmix.
  • Stir in boiling water until batter is smooth and without lumps.

Step 2: Bake the Cake

  • Pour the batter into the prepared baking pan.
  • Bake for 35-40 minutes, or until a toothpick inserted into the center comes out clean.
  • Let the cake cool in the pan for about 10 minutes before inverting onto a wire rack to cool completely.

Step 3: Prepare the Frosting

  • In a medium saucepan, combine soy milk and soy butter (or regular butter). Heat over medium heat until butter melts and a smooth sauce forms.
  • Remove from heat and stir in cocoa powder. Let the mixture cool slightly.
  • Gradually whisk in powdered sugar until frosting reaches desired consistency. Add vanilla extract.

Step 4: Frost the Cake

  • Once the cake is completely cooled, frost the top and sides with the soy milk frosting.
  • Decorate with your desired toppings, such as chocolate chips, sprinkles, or fresh fruit.

Tips for Success:

  • Use high-quality soy flour for the best results.
  • If you don’t have buttermilk, you can make your own by adding 1 tablespoon of lemon juice or white vinegar to 1 cup of regular milk and letting it stand for 5 minutes.
  • Don’t overmix the batter, as this can result in a tough cake.
  • To ensure even baking, rotate the pan halfway through the baking process.
  • Let the cake cool completely before frosting to prevent the frosting from melting.
