Creamy Peanut Butter:

Use creamy peanut butter for the cake batter to ensure a uniform texture. Chunky peanut butter may affect the consistency of the cake.

Proper Mixing:

Mix the cake batter until just combined after adding the dry ingredients. Overmixing can result in a dense and tough cake.

Adjust the consistency of the chocolate buttercream frosting by adding more or less heavy cream as needed. It should be smooth and easy to spread.
