Peanut Butter & Jam Bars

I am a big PB&J fan and I love combining the two ingredients in my recipes.

If you love the combination just as much as I do, you are gonna absolutely LOVE these bars.

These bars are deliciously thick, soft, and chewy, bursting with peanut butter flavour, and generously filled with jam centres.

They are super quick and easy to throw together, and you only need simple, staple ingredients!

Ingredients you’ll need

Here’s a list of ingredients you’ll need to make these bars. You can find my recipe card at the bottom of this post for the complete list with their amounts.

  • Plain/all-purpose flour
  • Baking powder
  • Baking soda
  • Salt
  • Unsalted butter: Melted.
  • Light brown sugar
  • Large egg
  • Vanilla extract
  • Smooth peanut butter
  • Seedless raspberry jam: You can use any flavour you like. I microwaved it for a few seconds to make it easier to spread.

To make these bars, simply grab a medium mixing bowl and whisk together the flour, baking powder, baking soda, and salt. Set aside.

TIP: For a speedy cooling time, place the pan in the freezer for 1 hour, then cut into bars.

NOTE: For best results, I highly recommend using the gram measurements (with a digital scale), rather than the cup measurements.

Cup measurements are simply not accurate enough, and I cannot guarantee the best results if you use them.
