Key Ingredients in Vegan Coffee and Walnut Cake
The secret to a successful vegan coffee and walnut cake lies in thoughtful ingredient swaps that maintain flavor and texture while keeping everything entirely plant-based.
- Flour: All-purpose flour or a blend with whole wheat gives structure and balance to the cake.
- Plant Milk: Almond milk, soy milk, or oat milk provide moisture and blend easily with other ingredients.
- Neutral Oil: Sunflower, canola, or vegetable oil replaces butter to keep the cake moist.
- Instant Coffee: Dissolved in warm water, it delivers the robust coffee flavor that defines the cake.
- Brown Sugar: Adds a caramel-like depth and helps with the rich texture.
- Chopped Walnuts: Offer crunch and earthiness in every bite, and can be lightly toasted for extra flavor.
- Vinegar or Lemon Juice: Reacts with baking soda for lift, helping the cake rise in the absence of eggs.
- Vegan Butter or Coconut Cream: Used in the frosting to provide a creamy texture and hold the coffee flavor.
Simple Vegan Coffee and Walnut Cake Recipe
For the Cake:
- 1½ cups all-purpose flour
- 1 cup brown sugar
- 1 tsp baking soda
- ½ tsp salt
- 1 tbsp instant coffee dissolved in 1 tbsp hot water
- 1 cup plant milk (soy, almond, or oat)
- â cup neutral oil
- 1 tbsp apple cider vinegar or lemon juice
- ¾ cup chopped walnuts
- 1 tsp vanilla extract
Instructions:
- Preheat oven to 350°F (175°C). Grease and line two 8-inch round cake pans.

- In a separate bowl, combine the plant milk, dissolved coffee, oil, vinegar, and vanilla extract.
- Pour the wet ingredients into the dry ingredients and mix gently until just combined.
- Fold in the chopped walnuts.
- Divide the batter evenly between the prepared pans and bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean.
- Allow cakes to cool completely before frosting.
For the Frosting:
- ½ cup vegan butter or solid coconut oil
- 2 cups powdered sugar
- 1 tbsp instant coffee dissolved in 1 tbsp hot water
- 1-2 tbsp plant milk (as needed for consistency)
- Optional: Chopped or halved walnuts for decoration
Frosting Instructions:
- Beat the vegan butter until light and fluffy.

Tips for the Best Vegan Coffee and Walnut Cake
- Use freshly brewed coffee: For a deeper coffee taste, you can use strong brewed espresso instead of instant coffee granules.
- Toast the walnuts: Lightly toasting the walnuts in a dry pan before adding them to the batter can enhance their flavor.
- Don’t overmix the batter: Stirring too much can make the cake dense. Mix until ingredients are just combined.
- Let the cake cool: Always ensure your cake is fully cooled before frosting to prevent melting or sliding layers.
