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.
Combine the peanut butter, confectioners' sugar, saltines, butter and salt in a bowl and blend with an electric mixer until well combined
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.
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.
Serve chilled or at room temperature.
