Creating the peanut butter swirl is easy — simply scrape batter into a baking pan that has been coated with nonstick cooking spray and lined with parchment. Be sure to spread the batter evenly. Add dollops of peanut butter to the top of the brownie batter. Then use a chopstick, skewer or the tip of a small knife to create peanut butter swirls by dragging the peanut butter through the brownie batter.

A Guide to Healthier Baking

Want to try adding prune puree to some of your own recipes? Here’s a handy how-to:

  • Swap for sugar: Use prune purée to replace anywhere from one-third to half of the sugar in a recipe.
  • Swap out eggs: To replace 1 large egg, use ¼ cup prune purée. Keep in mind that this works best in recipes that call for no more than 3 large eggs.
  • Lose the fat: To cut down on fat, replace up to half of the butter or oil with an equal amount of prune purée.
