Ingredients
- All purpose flour: Adds structure to the pastry Use fresh flour for best results
- Whole milk and water: Ensure tender puffs with a light interior Whole milk gives a richer flavor
- Unsalted butter: Gives rich taste and a delicate crumb Choose good quality butter for best flavor
- Eggs: Create lift and that signature hollow choux center Use large eggs at room temperature
- Fine salt: Balances sweetness and enhances flavor in both pastry and ganache Opt for pure sea salt
- High quality white chocolate: Key for both the ganache and sauce Look for couverture or a bar with cocoa butter as the first ingredient
- Heavy cream: Used in both the ganache and sauce Look for cream with at least 36 percent milk fat
- Vanilla extract: Deepens and rounds out the ganache flavor Use pure extract for best taste
- Orange zest: Optional but adds brightness to the ganache Choose unwaxed oranges and zest just before using
Step by Step Instructions
- Make the Choux Pastry:
- Combine water whole milk butter and fine salt in a saucepan Warm over medium heat to just a simmer allowing the butter to fully melt Stir gently so nothing scorches
- Add Flour and Mix to Dough:
- Once simmering dump in the flour all at once Stir vigorously using a wooden spoon Keep mixing until the mixture gathers into a ball and pulls cleanly away from the pan sides This should take about two minutes
- Cool the Dough:
- Remove from heat and spread dough in the pan to cool for five minutes Cooling prevents the eggs from scrambling when you add them
- Incorporate Eggs:
- Add one egg at a time to the slightly cooled dough Beat thoroughly after each addition The dough should become smooth thick and glossy It should drop in a thick ribbon from the spoon but not runny
- Pipe and Bake:
- Transfer dough to a piping bag with a large round tip Pipe even mounds approximately two inches wide onto a parchment lined baking sheet Leave space between each one
- Bake the Choux:
- Set in a preheated oven at four hundred degrees Fahrenheit Bake for twenty minutes then reduce temp to three hundred fifty degrees Fahrenheit and continue baking for another fifteen minutes They should be deeply golden and well puffed Remove and cool completely on a wire rack
- Prepare the Ganache:
- Place chopped white chocolate in a heatproof bowl Heat two thirds cup of heavy cream until just simmering Pour cream over the chocolate Let stand for two minutes then stir until perfectly smooth and melted
- Chill the Ganache:
- Stir in vanilla extract and a pinch of salt Cover and refrigerate until very cold about two hours Do not skip this step or the ganache will not whip properly
- Whip to Soft Peaks:
- Once ganache is fully chilled add the remaining cream Beat with an electric mixer until soft peaks form This should be light fluffy and able to hold its shape
- Prepare the Lava Sauce:
- Prepare the white chocolate lava by heating heavy cream until just below a boil Pour over chopped chocolate Let stand one minute then stir gently until glossy and fluid Keep the sauce warm for pouring
- Fill and Assemble:
- Slice the tops off each choux puff Pipe or spoon in generous amounts of whipped ganache Replace the tops so each one looks like a little volcano
- Lava Flow Finish:
- Plate each volcano and right before serving pour the hot white chocolate sauce over the top at the table For extra drama pour slowly and let the sauce run down the sides in rivulets

Watching the ganache transform from glossy to fluffy is always my favorite moment It reminds me of making holiday desserts with my grandmother who always insisted on using both milk and butter for the most tender choux
Storage Tips
Store unfilled choux pastry shells in an airtight container at room temperature for up to one day or freeze for longer storage Once filled serve immediately or within four hours for best texture The ganache and lava sauce can both be made up to two days in advance and kept chilled Assemble just before serving to keep everything crisp
Ingredient Substitutions
You can swap the white chocolate for milk or dark chocolate in the ganache or sauce for a richer flavor Twist in orange or lemon zest for a citrus note Dairy free versions of cream and butter with high quality vegan white chocolate will also work but the flavor changes
Serving Suggestions
Serve these with sparkling wine or a sweet dessert wine Fresh berries on the side make a beautiful contrast and a little sprinkle of toasted nuts gives a crunch If you want a more playful twist try adding edible glitter to the hot sauce for an extra magical reveal
