How To Make A Chocolate Box Cake Better Recipe Notes:
- You can also make these into cupcakes. There is plenty of frosting, so you can be generous with the frosting. Or you can cut the recipe in half if you want to lightly frost the cupcakes. Follow the box instructions for cooking times.
- This recipe will still use the ingredients on the box instructions, but you will make some substitutions. You will change the water to milk and add an extra egg. You will also use the oil on the package instructions. But it’s the addition of the pudding powder and sour cream that makes the cake extra moist!
- If you really want to up the flavor of the chocolate, you can add chocolate milk instead of plain milk.
- Add parchment paper to the bottom of the 9-inch cake pans to make sure the cakes can easily be removed from the pans.

Best Chocolate Cake Recipe
- 1 – box of chocolate cake mix ( I used Devils Food Chocolate)
- 1 – 1.4 box instant chocolate pudding
- 1 cup sour cream
- Change the water for milk according to the box instructions
- Add 1 extra egg according to the box instructions
- Add oil according to the box instructions
Instructions for the Best Chocolate Cake
- Preheat your oven to 325*. Add parchment paper to 9-inch pans and spray the pans with cooking spray. Set aside.
- Mix together the cake mix and pudding powder until combined.
- Add the rest of the ingredients and mix well. You should scrape down the sides to everything is mixed well. Mix for about 1 minute.
- Split the batter between the 2 cake pans. Tap them on the counter to spread out the cake mix and get out air bubbles.
- Bake for about 25 minutes. Poke a toothpick into the center and if it comes out clean – it’s done. Add 2 – 3 minutes and check it again until it’s cooked completely.
- Let cool completely before you add the icing.
Chocolate Buttercream Frosting:
- 2 sticks of butter, softened (1 cup)
- 1 cup of cocoa powder
- 2/3 cup hot water
- 1 teaspoon vanilla
- 8 cups powdered sugar
Instructions
- In a standing mixer add the butter, cocoa, hot water, vanilla. Mix for about 1 minute until well combined.
- Add all the powdered sugar and set the mixer to low.
- Once all the powdered sugar is mixed in let it whip on high for about 30 seconds until light and fluffy.
- Let it sit for about 10 minutes and add it to your cake!
Assembling the cake
- Add 1 layer of the cake to a plate. Add the chocolate frosting – be generous!
- Add the second layer. I like to spoon the icing on top of the cake and spread it around with a butter knife or mini frosting spatula.
- Pull the frosting down the sides of the cake to cover the sides.
- Finish the top of the cake and add more frosting.
- I added some frosting to a piping bag with a Wilton 402 open star piping tip and I swirled them around the top of the cake. I also put a bunch of stars around the bottom of the cake. But you don’t have to do this – it’s perfect without the extra icing decorations!
This is my little secret—it’s really easy, and you can apply it to all box cake mixes to make them taste like homemade! These box cake hacks can be our secret! If you are looking for how to make a box cake moist, this is a recipe you must try!
Don’t let all the instructions make it look difficult. It’s just adding a few extra ingredients to a box of cake mix, so it’s really simple. And it’s totally worth it to make homemade buttercream icing. It’s really not that difficult and tastes so much better than a jar of icing.

Although the cake taste delicious it did fall quite a bit. I’m glad I made cupcakes instead of a layer cake easier to hide the fall. I’d like to try it again but have to figure out why it fell.

Hi, I only have 8 inch pans, shall I put less batter in the pans or pour evenly and cook longer?

I'm so sorry! I don't use this recipe often for cupcakes. Im sorry I am not sure why they sink in the middle. Maybe add half the sour cream.
