Dulce de Leche and Nut–Butter Truffles

Ingredients

• 2 ounces 0%-cacao bittersweet chocolate finely chopped
• 2 tablespoons dulce de leche at room temperature
• 2 tablespoons peanut butter 
• 0.3 cup cocoa powder unsweetened (preferably Dutch-process)

Equipment

• bowl
• frying pan
• sauce pan
• sieve
• baking pan

Directions

1. Melt chocolate in a heatproof bowl set over a saucepan of barely simmering water, stirring occasionally until smooth.
2. Remove bowl from heat and stir in dulce de leche and nut butter. Cool slightly, then roll level teaspoons of mixture into balls and place on a tray. Chill completely, about 30 minutes.
3. Sift cocoa powder into a medium baking pan or onto a tray. Melt chocolate in a shallow heatproof bowl set over a saucepan of barely simmering water, stirring occasionally until smooth.
4. Remove pan from heat, leaving bowl over water. Dip truffles, 1 at a time, in chocolate, lifting out with a fork and letting excess drip off, then immediately transfer to cocoa, turning to coat.
5. Let stand until coating is set, then shake off excess cocoa in a sieve. (Remaining cocoa can be sifted and returned to container.)
6. Truffles are best the day they are made but can be frozen up to 2 weeks (do not keep at room temperature). Thaw at room temperature 1 hour before serving.
