Making Chocolate Peanut Butter Texas Sheet Cake is easy if you follow these steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C) and grease a 13×18 inch sheet pan.
2. Combine Dry Ingredients: In a large mixing bowl, mix together the flour, granulated sugar, cocoa powder, baking soda, and salt.
3. Boil Butter and Water: In a saucepan over medium heat, bring the butter and water to a boil. Once boiling, remove from the heat.
4. Mix Wet Ingredients: In a separate bowl, combine buttermilk, peanut butter, eggs, and vanilla. Whisk until smoothly combined.
5. Combine Mixtures: Pour the hot butter-water mixture into the dry ingredients. Stir until it’s well combined. Then add the wet mixture and mix until just combined and smooth.
6. Pour Batter: Pour the batter into the prepared sheet pan, spreading it evenly.
7. Bake: Bake for 20-25 minutes or until a toothpick inserted in the center comes out clean.
8. Cool Cake: Remove from the oven and let it cool in the pan for about 15 minutes.
9. Prepare Frosting: In a bowl, combine powdered sugar, cocoa powder, creamy peanut butter, and milk. Mix until smooth and creamy.
10. Frost the Cake: Once the cake is cool, spread the frosting evenly over the top.
11. Garnish: If desired, sprinkle chopped peanuts on top for extra crunch and flavor.
