Ingredients
Scale
- 8 slices soft white bread (or whole wheat, brioche, or sourdough)
- 4 tablespoons creamy peanut butter (Skippy Natural or Justin’s recommended)
- 4 tablespoons strawberry jam or jelly (seedless jam works best)
- 2 tablespoons unsalted butter, softened (optional, for toasting outside before freezing)
Instructions
- Set up your workstation. Lay out bread slices, peanut butter, jam, and butter. Have your cutter and a baking sheet lined with parchment paper ready.
- Lightly toast the bread on the lowest setting until just warm and slightly dry on the surface. Let cool for 2 minutes.
- Using a rolling pin, gently roll each slice to about 1/4-inch thickness, focusing on the center.
- Spread about 1 tablespoon of peanut butter on 4 slices of flattened bread, leaving a 1/2-inch border around the edges.
- Spread about 1 tablespoon of jam on top of the peanut butter on the same 4 slices, keeping the border clear.
- Place the remaining 4 slices of flattened bread on top of the filled ones. Press down gently around the edges.
- Place your uncrustable cutter or cookie cutter over the sandwich, centering it. Press down firmly and evenly. Twist slightly to release, then lift straight up. If using a fork, press tines firmly around the edges.
- Check the seal by running your finger around the edge of each sandwich. Press together any gaps or thin spots.
- Place sealed sandwiches on the parchment-lined baking sheet in a single layer. Freeze for 1-2 hours until solid.
- Transfer frozen sandwiches to freezer-safe zip-top bags, squeezing out as much air as possible. Label with the date and store for up to 3 months.
Notes
Lightly toasting the bread before assembly creates a better seal and prevents sogginess. Spread peanut butter on both slices of bread to act as a barrier against jam moisture. Flash freezing individually prevents sandwiches from sticking together. These taste better after a day or two in the freezer as flavors meld.
