Line a large baking sheet with parchment paper or a silicone baking mat. Arrange about half of the mini pretzels in a single layer on the pan, making sure they are not overlapping. These will be the bases for your bites.
60-70 mini pretzel twists or squares
Place one mini peanut butter cup on top of each pretzel base. Set the cups upright or upside-down; upside-down can help them sit flatter once the chocolate is added. If your kitchen is warm, keep the peanut butter cups chilled until just before using so they don’t soften too quickly.

In a microwave-safe bowl, combine the chocolate chips, peanut butter chips (if using), and creamy peanut butter. Microwave on 50% power in 30-second bursts, stirring well after each, until smooth and glossy, about 1½–2 minutes total. If the mixture is too thick, stir in 1–2 teaspoons of neutral oil or coconut oil, a little at a time, until it flows smoothly. Alternatively, melt gently over a double boiler, being careful not to let any water get into the bowl.

Using a small spoon, drizzle or spoon a portion of the melted chocolate mixture over each peanut butter cup, letting it drip down to coat the cup and contact the pretzel. Aim for about a heaping teaspoon per pretzel—enough to glue everything together without flooding the pan. If you prefer, transfer the melted chocolate to a small zip-top bag, snip a tiny corner, and pipe it over the tops.

If you want sandwich-style bites, gently press a second pretzel on top of each chocolate-covered peanut butter cup. Press just enough so it adheres without squeezing out too much chocolate. For open-face bites, skip the top pretzel.

While the chocolate is still glossy and not yet set, sprinkle the tops with a pinch of flaky sea salt. Add sprinkles, colored sugar, crushed candies, and/or crushed nuts as desired. Avoid piling on too much so toppings don’t slide off or make the bites hard to stack.

Transfer the baking sheet to the refrigerator and chill for 20–30 minutes, or until the chocolate is firm to the touch. For faster setting, chill in the freezer for 10–15 minutes, taking care not to leave them in for hours to prevent freezer odors.
Once the chocolate is completely set, gently peel each pretzel bite from the parchment. Serve on a platter, pack into gift tins or cookie boxes, or store in an airtight container. Keep at room temperature for up to 3–4 days, in the refrigerator for up to 2 weeks (with parchment between layers), or freeze for up to 2 months.
