Preheat your oven to 350°F (175°C). Grease a muffin tin or line it with paper liners.
To a microwave safe bowl add your peanut butter, then microwave it for 30-ish seconds just so it's easier to stir.
Add in your oats, almond flour, vanilla extract, applesauce, and egg. Mix well until everything is combined.
Add around 2 tbsp of the mixture to each muffin well, flattening out.
Add around 1/2 tsp jelly to each muffin, spreading out slightly with a spoon.
Bake for 12-15 minutes or until the oat cups are set and lightly golden brown.
Cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.
