If you want to make your own peanut butter, you don't have to spend any money on purchasing an expensive peanut butter machine. You can use everyday household appliances to make your own peanut butter and save money. Peanut butter is a simple recipe of peanuts, peanut oil and sweetener if you prefer. You can use a food processor or a blender to make your own homemade peanut butter in a matter of minutes.

Use an old blender for the sole purpose of making peanut butter. Because making peanut butter in a blender can add strain and wear on it, it's a good idea to use an old one. Spray the inside of the blender with non-stick spray to create a slippery wall so the peanut butter doesn't stick to the walls.

Use an old-fashioned coffee grinder with a crank. These coffee grinders are typically made from cast iron and have a handle at the top that is used to crush coffee beans into a powder form. Use this device to crush peanuts and make peanut butter.

Use a spice crusher as a peanut butter machine. A spice crusher is a bowl with a large tool used for crushing spices such as pepper, salt and dried leaves. This can be used to crush peanuts. This method is more labor intensive and will only produce crunchy peanut butter due to the lack of blending.
