About the ingredients
Method
- Start with ganache. Warm cream slowly in saucepan over medium-low heat; steam rising not boiling bubbles. Pour over chocolate in heatproof bowl; sit quiet 4 minutes. Whisk until velvet smooth. Stick in fridge while dough mixes.
- Melt peanut butter, powdered sugar, butter, salt in microwave-safe bowl at 60 seconds intervals. Stir thoroughly between. Should be loose but thick. Set this mixture aside; room temp is fine.
- Preheat oven to 405°F. Mix dough using stand mixer or handheld whisk; dry ingredients into wet one by one, beat till just combined. Sticky dough; dust hands lightly with flour if pressing into cups.
- Line muffins pan with liners. Scoop dough with medium cookie scoop. Press each into pan, spread fingers inside to form a well. Get dough up sides, no thin spots. If dough too sticky, flour fingertips; dough should hold shape without cracks.
- Bake 9-11 minutes. Edges start turning golden; centers will still look soft but not raw. Listen for faint crackle sound when edges set. Use wooden spoon back or round handle mid-bake, and again just before done to maintain cup shape. Dough will slump if you skip this step. Crucial.
- Cool cups in tin 15 minutes minimum before filling. When cool, spoon about 2 teaspoons peanut butter mix into each cup; dollop ganache on top carefully with tablespoon measure—just enough to cover peanut butter fully.
- Chill cookie cups for 45-60 minutes to firm ganache. Remove, let sit at room temperature 15 minutes before serving to sweeten chocolate aroma. Store leftovers in freezer up to 2 months in airtight container.
Cooking tips
Chef's notes
- 💡 Ganache stage critical. Warm cream slow; no boil or will seize chocolate. Pour over chopped chocolate, wait 4 full minutes for melting. Whisk after rest, texture should be silky, thick but pourable. Fridge chill ganache to firm up before using. Avoid hardening ganache too much; just firm to slick spatula consistency.
- 💡 Microwave peanut butter mix in bursts. Sixty seconds max, stir well between. Hot tends to separate or scorch. Butter melted evenly smooths peanut butter grit slightly but keep salt unsalted to prevent over-salty. Room temp mix holds but thick enough to dollop, not runny. Set aside while dough bakes.
- 💡 Dough sticky; flour hands sparingly. Press gently into muffin liners; thin walls collapse, thick ones bake unevenly. Use wooden spoon handle mid-bake to push walls up. Key to holding shape hence filling capacity. Skipping leads to flat cups, leaks during bake. Listen for crackling edges; golden color is go.
- 💡 Baking at 405°F hotter than normal. Crisp edges form fast, protect moist centers. Watch time 9 to 11 minutes. Centers look soft but not wet; springy feel. Mid-bake pressing essential. Leave in tins 15 mins after bake for partial set, avoids tearing.
- 💡 Cooling slow improves fill. Spoon peanut butter first, ganache top to cover precisely. Chill 45-60 mins minimum; ganache firms but not rock hard. Room temp rest 15 mins before serve wakes chocolate aroma. Store leftovers airtight freezer up to 2 months; thaw in fridge overnight before use. Do not skip temp steps.
Common questions
What if ganache seizes?
Usually cream too hot. Stop heat earlier next time. Add little warm cream in small increments. Stir gently till smooth. No whisk if lumps form. Chill after smoothing. Can try microwave very short bursts but risk overheat.
Can I use crunchy peanut butter?
Yes but texture changes. Adds crunch. Filling less smooth. Adjust powdered sugar for sweetness balance. Natural peanut butter can work but expect stickier dough. Butter important to mellow intensity. Trial batches advised.
Dough too sticky to handle?
Dust hands lightly with flour only. Don't overdo; dry dough tough. Keep dough cold if too warm, blends easier. Press firmly inside liners to avoid breaks. Wooden handle pressing mid-bake critical for shape retention.
How best to store leftovers?
Freeze in airtight container single layer or stacked with parchment. Thaw in fridge overnight. Ganache softens if left room temp too long. Can keep refrigerated short term but texture firmer and flavors restrained. Always cover tightly.
