I couldn't find any information on a product or recipe called "Diffusion Background Recipe Vector Vector PNG Product Recipe Wallpaper". It's possible that it's a fictional or non-existent product.

However, I can suggest some alternatives to find what you're looking for:

* Check online marketplaces like Amazon or Etsy for products related to recipes or cooking.
* Search for vector graphics or illustrations of food or cooking on websites like Vecteezy or Graphic River.
* If you have more information about the product, such as a description or keywords, I can try to help you find it.

If you're looking for a recipe for creating a diffusion background with a vector design, I can provide some general guidance:

* You can use a tool like Adobe Illustrator or Inkscape to create a vector illustration of your desired design.
* Use a high-resolution image editing software like Photoshop to edit and enhance the image.
* Save the edited image as a PNG file.

Alternatively, if you're looking for a recipe for creating a wallpaper with a diffusion background, I can suggest using a tool like Adobe After Effects or Blender to create a 3D animation of your design.
