Dairy Free Gluten Free Chocolate Cake

This nut-, egg-, dairy- and gluten-free chocolate cake is an ideal birthday cake for kids and adults living with multiple food allergies.

I made this cake for a friend’s daughter who celebrated her 7th birthday with us. Because her little brother is allergic to nuts, eggs and dairy, I wanted to bake something everyone could safely enjoy. The result was a simple, chocolatey layer cake that’s free of the most common allergens but still moist and delicious.

I adapted the recipe from a “Lighter Chocolate Cake” I found while flipping through my Martha Stewart’s Cakes cookbook. I was given that cookbook during a visit to Martha Stewart Headquarters in New York, and after spotting the original cake recipe I knew it would be a perfect base for an allergy-friendly version.

For this version I made three key changes: I removed eggs and dairy, made the cake gluten-free, and replaced canola oil with olive oil. The result is a deep chocolate cake that’s safe for many common allergies but still full of flavor.

Dairy Free Gluten Free Chocolate Cake Ingredients

1 cup warm water
½ cup unsweetened cocoa powder
1½ cups gluten-free all-purpose flour blend (use your preferred blend)
1 cup granulated sugar
¾ tsp baking soda
½ tsp salt
½ cup olive oil (plus 1 tsp for brushing the pan)
1 tbsp vanilla extract
2 tsp distilled white vinegar

Chocolate Glaze Ingredients

2 oz dark chocolate, finely chopped (ensure the brand is dairy-free)
½ cup confectioners’ sugar, sifted
2 tbsp water

Instructions

Preheat the oven to 375°F (190°C).
Brush an 8-inch round cake pan with 1 tsp of olive oil and set aside.
In a small bowl, whisk together the warm water and the unsweetened cocoa powder until smooth and well dissolved.
In a large mixing bowl, combine the gluten-free flour blend, granulated sugar, baking soda and salt.
Make a well in the center of the dry ingredients. Pour in the cocoa mixture, the olive oil and the vanilla extract.
Whisk everything together until the batter is smooth and uniform. Stir in the distilled white vinegar at the end — it will react with the baking soda and help the cake rise.
Pour the batter into the prepared cake pan and smooth the top.
Bake for 30–35 minutes, or until a toothpick inserted into the center comes out clean. Oven times vary, so check a few minutes early if your oven runs hot.
Remove the cake from the oven and allow it to cool in the pan for about 20 minutes. Transfer to a wire rack if desired to cool further before glazing.
While the cake is baking, prepare the chocolate glaze: set the chopped dark chocolate in a heatproof bowl over a pan of simmering water (double boiler). Stir the chocolate constantly until it melts and is smooth.
In a separate medium bowl, whisk the sifted confectioners’ sugar with 2 tablespoons of water until smooth and lump-free. Add the melted chocolate and whisk until the glaze is glossy and uniform. If the glaze is too thick, add a little more water, ¼ teaspoon at a time, until it reaches a spreadable consistency.
Once the cake has cooled for at least 20 minutes, spread the glaze evenly over the top. Allow the glaze to set for a few minutes before slicing.

Finish the cake with simple decorations — I added a few sparkler candles for the birthday celebration — and serve. This cake is delightfully dense and fudgy; one friend called it a “Texas Brownie Cake,” which simply means it’s rich and very satisfying.

Serve warm or at room temperature. Leftovers keep well covered at room temperature for a day or two, or refrigerated for up to five days. Bring refrigerated cake to room temperature before serving for the best texture and flavor.
