Ingredients
Units
Scale
- 57 g butter, melted
- 65 g peanut butter
- 120 g honey
- 120 g sourdough discard
- 5 g vanilla extract
- 55 g brown sugar
- 360 g rolled oats
- 3 g salt
- 163 g mini chocolate chips (optional)
Instructions
- Preheat and Prep: Preheat your oven to 325°F. Line a 9×9″ baking pan with parchment paper, leaving overhang on the sides for easy removal.
- Melt the Wet Ingredients: In a large bowl, microwave butter and peanut butter together for about 30 seconds until melted. Stir in honey, sourdough discard, and vanilla extract until smooth and combined.
- Combine Dry Ingredients: Add brown sugar, rolled oats, and salt to the wet mixture. Stir until every oat is coated. Fold in mini chocolate chips if using.
- Press Into Pan: Dump the mixture into the prepared pan. Place a piece of parchment paper on top and firmly press the mixture into an even, compact layer. Go over it once or twice — this step is critical for bars that hold together.
- Bake: Bake at 325°F for 25 minutes until the edges are lightly golden.
- Cool and Chill: Let the bars cool to room temperature in the pan. Cover and refrigerate for at least 1 hour, ideally 2 hours, to allow the bars to firm up completely.
- Slice and Store: Lift the slab out using the parchment overhang. Cut into 12 equal bars. Wrap individually in plastic wrap or beeswax wrap, or store in an airtight container.
Notes
Chocolate chips are listed as optional but highly recommended. Use old-fashioned rolled oats, not quick oats, for the best chewy texture. Be sure to press the mixture very firmly and evenly into the pan — this is the most important step for bars that hold together. Bars keep at room temperature for up to one week or in the freezer for up to one month.
