Instructions

1. Prepare the Cake

Preheat the oven to 350°F (175°C) and grease an 8×8-inch baking pan.

In a large mixing bowl, beat the butter, avocado oil, and sugar together until light and fluffy. This step helps create a soft, tender cake texture.

Add the egg, egg yolk, sour cream, and vanilla, mixing until smooth and fully incorporated.

In a separate bowl, whisk together the flour, black cocoa powder, salt, and baking powder.

Gradually mix the dry ingredients into the wet ingredients until just combined.

Pour in the chocolate milk and mix until the batter is smooth.

Spread the batter evenly into the prepared pan and bake for 30–35 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs.

Allow the cake to cool slightly in the pan.

2. Make the Ganache

While the cake cools, prepare the ganache.

Heat the heavy cream until just steaming. Pour it over the chocolate chips and allow it to sit for about 1 minute before stirring until smooth.

Reserve 2 tablespoons (30 mL) of the ganache for swirling into the buttercream later.

3. Create the Poke Cake

Using a fork or skewer, poke holes across the surface of the cake.

Pour the warm ganache over the cake, allowing it to soak into the holes. This step is what transforms the cake into a classic poke cake, adding extra moisture and deep chocolate flavor.

Let the cake cool completely before frosting.

4. Make the Buttercream

In a mixing bowl, beat the softened butter until smooth.

Add the powdered sugar and cocoa powder, mixing slowly at first and then increasing the speed until fluffy.

Mix in the vanilla and add a splash of cream if needed to reach a smooth, spreadable consistency.

Spread the buttercream evenly over the cooled cake.

Drizzle the reserved ganache across the top and gently swirl it into the frosting.

5. Make the Chocolate Curls

Melt the semisweet chocolate and butter together until smooth.

Spread the chocolate thinly on the back of a baking sheet and place it in the freezer for 3–4 minutes, just until firm.

Use a metal spatula to gently push the chocolate into curls. Keep the curls chilled until ready to decorate.

6. Decorate the Cake

Top the cake with chocolate curls, fresh figs, and greenery for a beautiful presentation.

These simple garnishes make this triple chocolate black cocoa poke cake especially lovely for spring and Easter celebrations.

Frequently Asked Questions

What does black cocoa powder taste like?

Black cocoa has a deep, smooth chocolate flavor that is less acidic than regular cocoa powder. It’s the cocoa used in chocolate sandwich cookies, which gives this cake its dark color and rich taste.

Can I make this cake ahead of time?

Yes. This cake actually tastes even better the next day as the ganache fully soaks into the cake. You can bake and frost it up to one day in advance.

How should I store this poke cake?

Store the cake covered at room temperature for up to 2 days, or refrigerate for up to 5 days. Allow slices to sit at room temperature briefly before serving so the buttercream softens.

Can I double the recipe?

Yes. Simply double the ingredients and bake the cake in a 9×13 pan. The baking time will increase slightly, usually around 35–40 minutes.

Dietary Substitutions

This cake is easy to adapt depending on dietary needs.

Gluten-Free Option
Substitute the flour with Bob’s Red Mill Gluten Free 1:1 Baking Flour, which works very well in cakes and produces a similar texture.

Dairy-Free Option
Use a dairy-free butter substitute and replace the heavy cream with plant-based heavy cream such as Silk brand cream.

Milk Substitute
If chocolate milk is unavailable, use regular milk mixed with 1 tablespoon cocoa powder and 1 tablespoon sugar.

Less Sweet Option
Swap the semisweet chocolate chips in the ganache for dark chocolate chips (60–70%).
