Preparation

  4. In another bowl, whisk together the flour and baking soda, then gradually add this mixture to the peanut butter mix until combined.

Baking

  2. Bake in the preheated oven for 20-25 minutes, or until lightly golden and a toothpick inserted comes out clean.
Cooling and Serving
  1. Allow the bars to cool in the dish for about 15 minutes before slicing them into squares.
  2. Serve warm and enjoy!

Notes

For a nut-free option, substitute peanut butter with sunbutter or any other nut-free alternative. Avoid overbaking to maintain chewiness. Store in an airtight container at room temperature for 3-4 days, refrigerate for up to a week, or freeze for up to three months.
