Step-by-Step Instructions

Preheat your oven to 350°F (175°C). Make sure the oven rack is in the center for even baking.
In a large mixing bowl, combine the chocolate cake mix, creamy peanut butter, eggs, and milk. Mix well until the batter is smooth and fully combined. Tip: If the peanut butter is very stiff, warm it for 10 to 15 seconds in the microwave to help it blend smoothly.
Pour the batter into a greased 9×13 inch baking dish, spreading it evenly. Use an offset spatula or the back of a spoon to smooth the surface so it bakes uniformly.
Sprinkle the chocolate chips evenly over the top of the batter. Distribute them so every slice will get melty chocolate.
Bake in the preheated oven for 30 to 35 minutes or until a toothpick inserted into the center comes out clean. If the top is browning too quickly, tent with foil for the last 10 minutes of baking.
Once baked, let the cake cool slightly in the baking dish. Cooling for 10 to 15 minutes helps the cake set and makes it easier to slice.
Dust with powdered sugar before serving. Enjoy! For a different presentation idea and related technique, see this Butter Pecan Cupcakes post for helpful plating tips: butter pecan cupcakes presentation.

Frequently Asked Questions

Can I use crunchy peanut butter instead of creamy?
Yes, you can use crunchy peanut butter, but the texture will be slightly chunkier and may create small pockets of peanut pieces in the cake.

Yes, lightly greasing the 9×13 inch baking dish prevents sticking and helps the cake release cleanly.
Will this recipe work with low-fat milk?
Yes, low-fat milk can be used. The cake may be a little less rich but will still bake properly.
Can I make this in a smaller pan?
This recipe is designed for a 9×13 inch pan. Using a smaller pan will change baking time and thickness, so adjust bake time and watch closely.
How do I know when the cake is done?
Insert a toothpick into the center; it should come out clean or with a few moist crumbs, not wet batter.
Can I add more chocolate chips?
Yes, you can increase the chocolate chips, but very large amounts may affect baking so keep it reasonable.
