Line a quarter sheet pan with parchment paper. A quarter sheet pan is around 13 x 9.6 inches, with a 1.1-inch height in its rim. Anything close to this will work perfectly.
In a mixing bowl add in your Greek yogurt, maple syrup/honey, and vanilla. Mix well to combine.
Transfer this mixture onto your prepared baking sheet and evenly spread with a spatula.
Add tiny dollops of jam and peanut butter every here and there, then swirl into the yogurt mixture using a knife or metal skewer.
Top with peanuts and raspberries.
Freeze for 3 hours up to overnight.
Slice or break into pieces and serve immediately or freeze in an airtight container for up to 1 week.
Enjoy!
