Peanut Butter Honey Flapjacks

Steps

1. 1

   Heat the oven to 350°F. Line an 8-inch square pan with parchment, leaving an overhang on two sides for lifting.

2. 2

   Put the butter, brown sugar, honey and salt in a medium saucepan over medium-low heat. Stir until the butter melts, the sugar dissolves and the mixture just bubbles at the edges, 3 to 4 minutes.

3. 3

   Take the pan off the heat and stir in the peanut butter until smooth. Add the oats and peanuts, if using, and stir until every oat is coated.

4. 4

   Tip into the pan and press very firmly into an even layer with the back of a measuring cup; firm packing is what keeps the bars from crumbling.

5. 5

   Bake until golden brown at the edges and just set in the middle, 20 to 25 minutes.

6. 6

   Cool in the pan for 15 minutes, score into 16 bars with a knife, then let cool completely, about 1 hour, before lifting out and cutting through. Store airtight up to 5 days.
