How to Make Peanut Butter Chocolate Layer Cake
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Prepare your cake pans by greasing them with butter or non-stick spray and dusting with flour.
Step 2: Mix Dry Ingredients
In a large mixing bowl, combine:
1. All purpose flour
2. Sugar
3. Cocoa powder
4. Baking soda

Whisk these ingredients together until well combined.

In another bowl, mix:
1. Milk
2. Vegetable oil
