Recipe Information
Ingredients
- 4 tablespoons Unsalted butter
- 1 cup Peanut butter (creamy or crunchy)
- 1 cup Brown sugar
- 1 teaspoon Vanilla extract
- 1 cup All-purpose flour
- 1 cup Jam or jelly (any flavor of choice)
- 0.5 teaspoons Salt
- 0.5 cup Rolled oats
- 0.25 cup Chocolate chips or chopped nuts (optional)
Instructions
Grease an 8x8-inch microwave-safe dish or line it with parchment paper for easy removal.
In a microwave-safe bowl, melt the butter on high power in 20-second intervals until fully melted.
Add the peanut butter and brown sugar to the melted butter. Microwave for 30 seconds, then stir until the mixture is smooth and combined.
Mix in the vanilla extract and salt. Stir thoroughly.
Gradually add the flour to the mixture, stirring until fully incorporated.
Fold in the rolled oats to add a bit of texture to the dough. If desired, mix in chocolate chips or chopped nuts at this stage.
Press half of the dough evenly into the prepared dish to form the base layer.
Spread the jam or jelly evenly over the base layer, leaving a small border around the edges to prevent overflow.
Crumble the remaining dough over the jam layer, pressing down lightly to ensure it adheres.
Microwave on high power for 4–5 minutes, checking after 4 minutes to avoid overcooking. The bars are done when the edges are firm but the center is slightly soft; it will firm up as it cools.
Allow the dish to cool completely before slicing into bars. This may take about 30 minutes at room temperature.
Serve the bars and enjoy! Store leftovers in an airtight container at room temperature for up to 3 days or refrigerate for up to a week.
