Step 1

Melt the chocolate in the top of a double boiler. Keep the chocolate warm over low heat until you are ready to start assembling the peanut butter cups.

Step 2

Combine the peanut butter, confectioners' sugar, saltines, butter and salt in a bowl and blend with an electric mixer until well combined

Step 3

Prepare a muffin pan with 18 paper muffin liners. Add 1 teaspoon melted chocolate to the bottom of a muffin liner. Using the teaspoon, spread the chocolate in a thin, even layer on the bottom and a third of the way up the side. Repeat with the remaining liners. Place the muffin pan in the freezer until the chocolate is set and hardened, about 5 minutes.

Step 4

Spread 2 heaping teaspoons of the peanut butter filling in the bottom of a chocolate-coated muffin liner (it should come to below the chocolate line). Top the peanut butter filling with 2 more teaspoons of melted chocolate, spreading it over the top so no filling is visible. Repeat with the remaining liners. Freeze for 10 minutes.

Step 5

Serve chilled or at room temperature.
