Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

1 (5 ounce / 142 g) package non-instant chocolate pudding mix
1 (18.25 ounce / 517 g) package chocolate cake mix
1 cup (170 g) semisweet chocolate chips
1 ½ cups (180 g) chopped walnuts

Directions

Preheat your oven to 175°C (350°F). Grease and lightly flour a 9×13 inch (23×33 cm) baking pan.

In a large saucepan, prepare the chocolate pudding according to the package instructions. Once the pudding has thickened, remove it from the heat.

While the pudding is still hot, add the chocolate cake mix directly into the saucepan. Stir thoroughly until the mixture becomes smooth and fully combined with no dry pockets.

Pour the batter evenly into the prepared baking pan. Sprinkle the semisweet chocolate chips and chopped walnuts evenly over the top.

Place the pan in the preheated oven and bake for about 25 minutes, or until a toothpick inserted into the center comes out clean.

Remove from the oven and allow the cake to cool before slicing and serving.

Variations

You can swap the walnuts for pecans or almonds if you prefer a different nut flavor. For a nut-free version, simply omit the nuts and add extra chocolate chips or shredded coconut. A drizzle of chocolate or caramel sauce on top after baking can add extra richness. You can also mix in a teaspoon of instant coffee powder with the cake mix to deepen the chocolate flavor.

Storage/Reheating

Store the cake in an airtight container at room temperature for up to 3 days. If you prefer longer storage, keep it in the refrigerator for up to 5 days.

To reheat, place a slice in the microwave for about 10 to 15 seconds to restore its soft texture. You can also enjoy it cold, as it remains moist and flavorful.

FAQs

Can I use instant pudding instead of non-instant?

No, non-instant pudding is required because it cooks on the stovetop and creates the proper texture for the batter.

Can I make this cake without nuts?

Yes, simply leave out the walnuts or replace them with extra chocolate chips or another topping.

Do I need to prepare the cake mix separately?

No, the cake mix is added directly into the hot pudding without following the box instructions.

What type of chocolate chips works best?

Semisweet chocolate chips are ideal, but you can use dark or milk chocolate depending on your taste.

Can I use a different pan size?

A 9×13 inch pan is recommended. Using a smaller pan may require longer baking time.

How do I know when the cake is done?

Insert a toothpick into the center; if it comes out clean or with a few crumbs, the cake is ready.

Can I freeze this cake?

Yes, wrap it tightly and freeze for up to 2 months. Thaw at room temperature before serving.

Why is my batter thick?

The batter is naturally thick due to the pudding. This is normal and results in a dense, moist cake.

Can I add frosting?

This cake is designed to be served without frosting, but you can add a light glaze or frosting if desired.

Is this cake good for travel?
