In a medium sized bowl, combine the yogurt and peanut butter. Stir with a rubber spatula until completely combined.
Place either a piping bag or ziplock bag into a tall large glass for easy transfer of the peanut butter yogurt (see pictures above). Using the rubber spatula, move the peanut butter yogurt into the bag.
Cut the piping bag or ziplock at the end to create a slit so you can pipe (see pictures above).
Pipe the peanut butter yogurt into the raspberries until the raspberries are full.
You can store in an airtight container in the fridge for up to 3 days. Enjoy!:)
