Quarter your strawberries and add them to a bowl. Sprinkle with the sugar and mix to combine. Set aside in the fridge for at least an hour to allow the natural juices to emerge.
Next, add the Greek yogurt, peanut butter, honey, and vanilla to a bowl. Mix well so that everything is well incorporated.
Add your whole pretzels to a ziptop bag and crush lightly with a rolling pin. Set aside.
Gather 4 glass or clear plastic cups. Start with a heaping tablespoon of crushed pretzels in the bottom of the dish.
Then, top with a few tablespoons of the peanut butter mixture.
Next, top with a heaping tablespoon of strawberries and syrup.
Repeat with pretzels and the last layer of the peanut butter mixture. Top with a strawberry slice and a whole pretzel.
Cover and refrigerate until ready to serve.
