Instructions Checklist

  • Beat cake mix, water, eggs, and oil in a large bowl with an electric mixer until combined. Pour batter into the prepared pan.

  • Bake in the preheated oven until a toothpick inserted into the center comes out clean, about 30 minutes. Let cool.

  • Poke holes all over the cake using the handle of a wooden spoon. Whisk milk and pudding mix together in a bowl until just starting to thicken. Pour over cake, spreading with spatula to fill the holes. Refrigerate to firm, about 1 hour.

  • Place chocolate chips in a glass bowl. Heat heavy whipping cream in a small saucepan over medium-low heat, stirring frequently, until bubbles form, about 3 minutes. Pour over the chocolate chips; whisk until smooth. Spread chocolate ganache over cake with a spatula.

Cook's Note:

You can eat this right away, but I prefer to refrigerate and consume the next day. This lets the ingredients come together to make the cake insanely moist and the ganache thicken.

I must have done something wrong. Pudding didn’t go down in holes. Also, I thought the chocolate ganache was too thick! Read More

There's nothing here not to like! I made the boxed cake mix just like it is written for the brand I bought (just less oil). I poured the pudding over and let that sit overnight. The next morning I poured the chocolate over the cake and let that sit for several hours. Everyone loved it and it was simple to make! Read More

I didn't make any changes to this recipe. However I agree with another reviewer that the 2 boxes of pudding produces way too much. I made both boxes and could not put it all on the cake without it overflowing. I don't know if I could have fit more if I'd poked more holes in the cake. Don't make the mistake that I made and start making the pudding too early. Wait until the cake is cooled before mixing the pudding as it thickens quickly. The chocolate topping was really quite simple to make and delicious. However I found it took at least 10 min. on med-low heat for bubbles to appear not the 3 min. written in the recipe. After spreading the pudding on the cake make sure to refrigerate for an hour before spreading on the chocolate. As suggested after spreading on the chocolate let it harden in the fridge overnight as suggested for best results. Keep in fridge until serving as the chocolate gets more gooey (and harder to cut) as it warms up to room temperature. I had many positive comments about this cake from family! It made 16 good-sized pieces. Read More

I didn 't like this cake me ( neither did my Son in Law famous for eating Everthing) used 1 box of pudding and still the cake was a gooey mess. Probably the box mix which always taste to me as an artificial case like creation. I always try these recipes hoping for a miracle that the box cake will taste better or at least not bad. BTW I always use Angel food box cakes because 1. I don't like Angle Food cake so I won't be eating it 2. No way am I using a dozen eggs for something I am not eating. Read More
