Use good quality Dutch-processed cocoa powder for best flavor. Ensure your gluten-free all-purpose flour blend contains xanthan gum, or add it separately.

Measure flour correctly by spooning it into the measuring cup and leveling it off; do not pack it.

Do not overmix the batter once wet and dry ingredients are combined, to keep the crumb tender.

Using hot water or coffee helps to ‘bloom’ the cocoa powder, intensifying chocolate flavor and contributing to a moist crumb.

Ensure vegan butter is truly softened to room temperature for a light, fluffy frosting.

Always allow cakes to cool completely on a wire rack before frosting to prevent melting and a messy cake.

This recipe is forgiving: most GF flour blends with xanthan gum and any unsweetened non-dairy milk work. Vegetable oil can be swapped for cooled melted coconut oil (adds slight coconut flavor) or applesauce (denser cake).

To enhance chocolate, add vegan chocolate chips, or substitute hot water with hot brewed coffee. For different flavors, add a pinch of cinnamon, dash of cayenne, or instant espresso powder.

Frosting can be varied with vegan vanilla buttercream or raspberry frosting. A sprinkle of flaky sea salt on top can elevate flavors.

Store frosted cake in an airtight container at room temperature for 2-3 days, or refrigerate if kitchen is warm (let come to room temp before serving).

Unfrosted layers can be wrapped tightly and stored at room temp for 3 days or refrigerated for 5 days. Layers can be frozen for 2-3 months (wrap plastic/foil, thaw in fridge). Individual frosted slices can be frozen for up to 1 month.

Serve with fresh berries (raspberries, strawberries), a scoop of vegan vanilla ice cream, or a hot cup of coffee or herbal tea for complementary flavors and textures.
