These Peanut Butter Oatmeal Bars are a deliciously chewy and wholesome treat combining the nuttiness of peanut butter with the hearty texture of rolled oats. Perfect as a snack or a sweet breakfast option, they feature a buttery oat base topped with a smooth peanut butter layer and a crumbly oat topping, baked to golden perfection.

  • Total Time: 1 hour 30 minutes
  • Yield: 9 servings

Ingredients

Dry Ingredients

  • 1 cup (150 g) all-purpose/plain flour
  • 1 cup (80 g) old-fashioned rolled oats
  • 1/2 tsp sea salt
  • 1/2 tsp baking/bicarb soda

Wet Ingredients

  • 1/2 cup (125 g) butter – melted
  • 1/3 cup (70 g) brown sugar
  • 2 tsp vanilla bean paste
  • 1 cup peanut butter (preferably crunchy)
  • 2 tbsp maple syrup

Instructions

  1. Preheat Oven: Preheat your oven to 175°C (350°F) to ensure it’s at the right temperature when ready to bake.
  2. Prepare Baking Dish: Line a 20 x 20 cm (8 x 8 inch) baking dish with non-stick baking paper, leaving an overhang for easy removal of the bars later.
  3. Mix Dry Ingredients: In a medium bowl, combine the flour, rolled oats, sea salt, and baking soda; mix thoroughly to distribute evenly.
  4. Combine Wet Ingredients: Melt the butter and add it to another bowl along with the vanilla bean paste and brown sugar; stir to blend well.
  5. Combine Mixtures: Add the wet mixture to the dry ingredients and mix until well combined into a cohesive dough.
  6. Press Base Layer: Reserve about 1/4 of the mixture (approximately 100 g or a firmly packed 1/2 cup). Firmly press the remaining 3/4 of the mixture evenly into the bottom of the prepared baking dish. Bake this base for 10 minutes.
  7. Prepare Peanut Butter Topping: While the base bakes, mix the peanut butter and maple syrup in a small bowl. If the peanut butter is thick, warm it briefly in the microwave to soften for easier spreading.
  8. Layer Peanut Butter: Remove the partially baked base from the oven and immediately spread the peanut butter mixture evenly over it.
  9. Add Crumble Topping: Crumble the reserved oat mixture over the peanut butter layer using your fingers for a crumbly topping.
  10. Bake Bars Fully: Return the baking dish to the oven and bake for an additional 10 minutes or until the topping is cooked through and a light golden brown.
  11. Cool Bars: Remove the bars from the oven and let them cool for 30 minutes at room temperature.
  12. Chill and Cut: Refrigerate the bars for another 30 minutes or until completely cool before cutting into squares to prevent crumbling.

Notes

  • Note 1: All-purpose flour can be substituted with gluten-free flour for a gluten-free version, but texture may slightly vary.
  • Note 2: Using old-fashioned rolled oats provides the ideal texture; instant oats may result in a less chewy bar.
  • Note 3: Crunchy peanut butter adds a nice texture contrast, but smooth peanut butter can be used if preferred.
  • Note 4: Maple syrup adds natural sweetness; honey can be substituted but will slightly change flavor.
  • For best results, avoid cutting the bars while they are warm to maintain their shape.
  • Use parchment paper with an overhang for easy removal of bars from the baking dish.
