Ingredients

1 box (15.25 oz) chocolate cake mix
1 small box (3.4 oz) instant chocolate pudding mix
1 cup milk (whole milk preferred)
1 package (8 oz) mini peanut butter cups, roughly chopped

Instructions

Step 1: In a large mixing bowl, whisk together the instant pudding mix and milk until smooth.
Step 2: Stir in the chocolate cake mix until the batter is thick and well combined.
Step 3: Fold the roughly chopped peanut butter cups into the batter evenly.
Step 4: Pour the mixture into a greased 13 x 9 inch baking dish and spread evenly.
Step 5: Bake at 180°C (350°F) for about 25 minutes, or until a skewer inserted in the centre comes out clean.
Step 6: Allow the cake to cool slightly before serving. It’s wonderful warm, especially with ice cream.

Tips & Variations

Don’t overmix the batter after combining the ingredients to keep the texture tender.
Chop the peanut butter cups into varying sizes to create pockets of gooey peanut butter.
The batter will be much thicker than typical cake batter—this is normal and results in a fudgy texture.
Check the cake starting at 20 minutes to avoid overbaking; a few moist crumbs on the skewer are perfect.
Serve warm with vanilla ice cream, whipped cream, or a drizzle of hot fudge sauce for extra indulgence.
Swap peanut butter cups for your favorite chocolate bars or add chocolate chips for variety.

Storage

Store leftover cake covered in the refrigerator for up to 3 days. Reheat individual slices in the microwave for 15-20 seconds before serving. You can also freeze the cake for up to 3 months by wrapping slices in plastic wrap and placing them in a freezer-safe container. Thaw in the fridge overnight before reheating.

The top layer is studded with scattered round and mini peanut butter cup pieces that add a shiny and smooth texture contrast.

FAQs

What is a dump cake?

A dump cake is an easy dessert where all the ingredients are simply “dumped” together and baked without complicated steps like creaming or folding. Traditional dump cakes often layer cake mix, fruit, and butter, but this recipe uses pudding and milk to create a moist, fudgy texture.

Can I use a different flavour of cake mix?

Yes, feel free to experiment with other cake mix flavors like vanilla or peanut butter for a different twist on this recipe. Just keep in mind that the chocolate pudding mix will keep the cake moist and fudgy regardless of your choice.
