Ingredients

• 1 box (15.25 oz) chocolate cake mix
  Provides the base structure and chocolate flavor for the cake. Using the full box keeps the batter rich and chocolaty.

• 1 cup creamy peanut butter
  Adds nutty richness and moisture. If your peanut butter is stiff, warm briefly to make mixing easier.

• 3 large eggs
  Bind the batter and add lift and structure to the cake.

• 1 cup milk
  Thins the batter for proper consistency and keeps the crumb tender. Whole milk yields a richer result.

• 1 cup chocolate chips
  Melty pockets of chocolate across the top and interior for extra chocolate intensity.

• Powdered sugar (for dusting)
  A light dusting brightens the top and adds a hint of sweetness for presentation.

Step-by-Step Instructions

1. Preheat the oven to 350°F (175°C). Position the oven rack in the center for even baking. Grease a 9×13 inch baking dish and set it aside.

2. In a large mixing bowl, add the chocolate cake mix, creamy peanut butter, eggs, and milk. If the peanut butter is very stiff, warm it in the microwave for 10 to 15 seconds to make it easier to blend.

3. Mix all ingredients together until the batter is smooth and fully combined. Scrape down the sides of the bowl with a spatula to ensure there are no dry pockets of cake mix.

4. Pour the batter into the prepared 9×13 inch baking dish. Use a spatula to spread it evenly into the corners for uniform baking.

5. Sprinkle the chocolate chips evenly over the top of the batter. This creates melty pockets of chocolate on the surface and in the finished slices.

6. Bake in the preheated oven for 30 to 35 minutes. Check for doneness by inserting a toothpick into the center; it should come out clean. If the top is browning too quickly, tent the pan loosely with foil for the last 10 minutes of baking.

7. Remove the cake from the oven and let it cool slightly in the baking dish for about 10 to 15 minutes. Dust the top with powdered sugar before slicing and serving.

Tip: For a gooier center, reduce baking time by a few minutes and check often. For a firmer cake, bake toward the longer end of the time range.

Frequently Asked Questions

Q: Can I use crunchy peanut butter instead of creamy?
A: Yes. Crunchy peanut butter will add texture and small nut pieces throughout the cake.

A: No, sifting is not necessary. Mix the dry mix directly with the wet ingredients until smooth.

Q: Can I use a different pan size?
A: For best results use a 9×13 inch pan as instructed. A smaller pan will change baking time and texture.

Q: How do I know when the cake is done?
A: Insert a toothpick into the center. It should come out clean or with a few moist crumbs, not wet batter.

Q: Can I reduce the sugar content?
A: The recipe uses boxed cake mix and chocolate chips, so sugar content is set by those products. You could try a lower sugar chocolate chip brand, but do not change ingredient quantities.

Q: Is this cake safe to make ahead?
A: Yes, bake and cool the cake, then store covered. Rewarm slices briefly before serving for a fresh-baked feel.
