Ingredients for betty crocker chocolate eclair

Twelve ingredients transform into Betty Crocker's signature choux pastry and velvety chocolate ganache.

The choux pastry hinges on precise ingredient ratios and temperature control. Unsalted butter must be cold and cubed—European-style butter like Plugrá or President works best for its higher fat content. All-purpose flour should be sifted to eliminate lumps, ensuring a smooth batter. Diamond Crystal kosher salt dissolves more easily than table salt, so use exactly 0.5 teaspoon. Eggs should be at room temperature for even incorporation, and dark chocolate chips with 70% cacao or higher deliver the rich, bittersweet flavor Betty Crocker perfected. For the ganache, 8 ounces of 70% cacao dark chocolate bars—like Lindt or Ghirardelli—melt smoothly with whole milk for a glossy finish.

No butter? Coconut oil works in a pinch, though the texture won’t be identical. Substitute heavy cream with half-and-half if needed, but expect a slightly lighter ganache. Vanilla extract can be swapped for vanilla bean paste for deeper flavor, though pure Madagascar extract is traditional. For the powdered sugar, confectioners' sugar from Domino or Dixie Crystals ensures a fine, smooth dusting. If you lack dark chocolate bars, chocolate chips can be melted with a splash of cream for the ganache, though bars yield a glossier result. The granulated sugar in the ganache balances bitterness—Turbinado sugar adds a subtle caramel note if you prefer a more complex flavor.

Choux pastry must bake immediately after piping to maintain its structure—do not refrigerate before baking. Once cooled, éclairs keep 2 days at room temperature in an airtight container, though the ganache may soften in warm climates. For longer storage, freeze filled éclairs for up to 1 month, thawing at room temperature before serving. Ganache leftovers can be reheated gently in the microwave or double boiler and reused within 3 days. Decorate just before serving to maintain the powdered sugar’s crispness—moisture is the enemy of that signature dusting.

Step-by-step instructions for Betty Crocker's chocolate eclair recipe

Master the art of light, crisp choux pastry and rich chocolate ganache for perfect eclairs every time.

In a medium saucepan, combine the 1 cup water and 0.5 cup unsalted butter over medium-high heat. Bring to a boil, then immediately remove from heat and add the 1.5 cups all-purpose flour all at once. Stir vigorously with a wooden spoon until the mixture forms a smooth dough that pulls away from the sides of the pan.

Return the pan to low heat and continue stirring until the dough becomes dry and forms a ball that leaves a thin film on the bottom of the pan. This should take about 3-4 minutes. Remove from heat and let cool for 5 minutes while you prepare the egg mixture. The dough should be slightly warm but not hot when you add the eggs.

In a large bowl, beat the 4 whole large eggs with the 0.25 cup granulated sugar and 1 tsp vanilla extract until the mixture is pale and slightly thickened. This should take about 2-3 minutes with a hand mixer or 5 minutes by hand.

Gradually add the cooled choux dough to the egg mixture, folding gently with a spatula until fully combined. The batter should be smooth and thick enough to hold its shape when piped. If the batter is too thin, let it rest for 10 minutes before proceeding. This resting time allows the gluten to relax, ensuring light, airy eclairs.

Preheat your oven to 400°F. Transfer the choux batter to a piping bag fitted with a large star tip. Pipe 4-inch long strips onto a parchment-lined baking sheet, spacing them about 2 inches apart. For classic eclairs, pipe them horizontally, but you can also pipe them vertically for a different look.

Bake for 20-25 minutes until the eclairs are deep golden brown and sound hollow when tapped on the bottom. Avoid opening the oven door during baking, as the sudden temperature change can cause the eclairs to collapse. Let them cool on the baking sheet for 10 minutes before transferring to a wire rack to cool completely.

In a heatproof bowl, combine the 8 oz dark chocolate bars (chopped) and the 1 cup heavy cream. Place the bowl over a saucepan of simmering water, ensuring the bottom of the bowl doesn't touch the water. Stir gently until the chocolate and cream melt completely, then remove from heat.

Let the mixture cool for 5 minutes, then whisk in the 0.25 cup milk to thin the ganache slightly. The ganache should be smooth and pourable but still thick enough to coat the eclairs. If it's too thick, warm it gently over simmering water for 30 seconds and whisk again. If it's too thin, chill it for 10 minutes to thicken.

Using a piping bag fitted with a small round tip, pipe the ganache into one end of each eclair until it reaches the other end. Place the eclairs on a wire rack set over a sheet of parchment paper to catch any drips. Let them set for 30 minutes at room temperature until the ganache is firm but still glossy.

Once set, dust the eclairs generously with the 2 cups powdered sugar using a fine-mesh sieve. For extra flair, you can also drizzle additional melted chocolate over the top or add chocolate shavings. Serve immediately for the best texture, or store in an airtight container in the refrigerator for up to 3 days. Bring to room temperature before serving for the perfect balance of crisp shell and velvety filling.

Common mistakes when making this dish

Overmixing the Batter

Choux pastry relies on delicate structure, and overmixing after adding eggs can deflate the air pockets, resulting in dense, heavy éclairs. Once you've combined the dough and eggs, fold just until fully incorporated—no more than 10-12 strokes with a spatula.

I've ruined entire batches by overmixing, so resist the urge to "get it all in." The batter should look smooth but still hold its shape when piped. 💫

Skipping the Resting Time

The 10-minute rest after mixing is non-negotiable for light éclairs. This allows the gluten to relax, preventing cracks and ensuring a smooth texture. I once baked éclairs without resting, and they turned out lumpy and uneven.

If your batter looks too thin after resting, let it sit another 5 minutes—it will thicken as it cools.

Opening the Oven Too Soon

Choux pastry is finicky about temperature changes. Opening the oven door before 20 minutes can cause the éclairs to collapse or develop cracks. I learned this the hard way when I peeked at 15 minutes and ruined a batch.

Keep the oven door closed until they're deep golden brown and sound hollow when tapped. Patience here is key!

Uneven Pipe Pressure

Inconsistent pressure while piping leads to éclairs that are too thick or too thin. Hold the piping bag at a 45-degree angle and apply steady, even pressure—don’t squeeze too hard or too lightly.

I use a Wilton 1M tip for classic éclairs and practice on parchment paper first. If the batter leaks or pools, your tip might be too large or your angle too steep.

Ganache Too Hot or Cold

Ganache must be lukewarm when piped—not hot (it’ll melt the eclair) and not cold (it won’t set properly). Test by dripping a small amount onto a plate: it should spread slightly but firm up in 1-2 minutes.

I once used ganache straight from the microwave, and it turned grainy. If yours is too thick, warm it gently over simmering water for 30 seconds; if too thin, chill for 10 minutes before piping. ⏰

Rushing the Setting Time

Ganache needs 30 minutes to set fully before dusting with powdered sugar. Skipping this step means the sugar will clump or slide off. I’ve seen beautiful éclairs ruined by impatience!

Place them on a wire rack over parchment to catch drips, and resist the urge to refrigerate—the cold air can cause condensation, making the sugar sticky.
