For the ganache lava center:
- Heavy cream
- Semi-sweet chocolate chips or chopped chocolate
- Mini Reese’s Peanut Butter Cups (frozen before baking)
For the cookie dough:
- Unsalted butter
- Granulated and brown sugar
- Eggs and vanilla
- All-purpose flour, baking soda, baking powder, and salt

- Creamy peanut butter (for the peanut butter dough)
Full ingredient measurements are listed in the recipe card below.

How to Make PB Choco Lava Cookies
- Make the ganache. Combine warm cream and chocolate until smooth, then chill until thickened.
- Freeze the mini Reese’s cups. This keeps them intact during baking.
- Mix your cookie dough. Cream butter and sugars, then beat in eggs and vanilla.
- Divide the dough. Add cocoa to one half and peanut butter to the other.
- Marble and fill. Swirl both doughs together, flatten, then stuff with a frozen Reese’s and a spoonful of ganache.
- Seal and chill. Roll into thick dough balls and chill so they bake tall and gooey.
- Bake. Pull them from the oven when the edges are set but the centers still look soft.
- Cool slightly. Then break one open and watch the lava flow!
Expert Tips for Bakery-Style Lava Cookies
✅ Chill the dough — it keeps your cookies thick and prevents spreading.
✅ Freeze the Reese’s cups — that’s the secret to keeping that perfect peanut butter layer.
✅ Don’t overbake — soft centers give you that molten lava texture.
✅ Want extra drama? Warm them just before serving or drizzle melted chocolate over the top.

How to Store and Freeze Them
- Room temperature: Keep in an airtight container for up to 4 days. Microwave before serving to re-melt the center.
- Freeze baked cookies: Wrap individually and store up to 2 months. Reheat 15–20 seconds for that gooey effect.
- Freeze unbaked dough balls: Freeze fully assembled and bake straight from frozen, adding 1–2 minutes to the bake time.

FAQ
Can I make these ahead of time?
Yes! Assemble the dough balls and freeze them until you’re ready to bake. They go straight from freezer to oven.
Can I skip the ganache?
You can, but you’ll lose that signature lava flow. The Reese’s cup alone will melt slightly but not fully ooze.
Can I make them smaller?
Absolutely! Just use half the dough per cookie and reduce the baking time by about 3 minutes.
