These brownies use creamy or crunchy peanut butter, browned butter, eggs, all-purpose flour, white and brown sugar, vanilla, baking powder, salt, and semi-sweet chocolate chips. A few tablespoons of seedless jam give a pretty swirl, and flaky sea salt is optional but recommended to enhance the flavors.

Variations

  • Change the jam: Strawberry, raspberry, or apricot jam each give a different fruity accent to the swirl.
  • Chocolate drizzle: Melt extra chocolate chips and drizzle over cooled brownies for a richer finish.
  • Gluten free: Replace the all-purpose flour with a 1:1 gluten-free flour blend for a gluten-free version that stays fudgy.

The following is a brief walkthrough of the method. Full, step-by-step instructions are in the recipe card below.

  1. Bake for 30–35 minutes. The center may look slightly underdone; it will set as it cools. For chewier brownies, aim for the lower end of the baking time. Cool in the pan 20–30 minutes before lifting out on the parchment and transferring to a wire rack.

Expert Tips

  • Watch the bake time: Pull the brownies when the edges are set and the center is a bit soft; they firm up while cooling.
  • Brown your butter: Browning adds a nutty, caramelized flavor that boosts the overall taste—don’t skip it.
  • Don’t overmix: After adding flour, mix only until combined to avoid a tough texture.

FAQs

Here are answers to common questions about these brownies.

Can I use crunchy peanut butter instead of creamy?

Yes. Either creamy or crunchy peanut butter works well; crunchy will add extra texture.

How do I know when the brownies are done baking?

The edges should be set and the top should look matte while the center remains slightly soft. Remove them and let them cool in the pan—the center will firm up as they cool.

Can I make these brownies ahead of time?

Yes. Store in an airtight container at room temperature for up to 4 days, refrigerate for up to a week, or freeze for up to 3 months.
