Chocolate Crepes:
- 3/4 cup (1 1/2 sticks) cold unsalted butter, cut into pieces, plus melted for pan
- 8 ounces semisweet chocolate, finely chopped
- 1 1/2 cups all-purpose flour
- 1/3 cup sugar
- 1/2 teaspoon salt
- 2 1/2 cups whole milk, room temperature
- 6 large eggs, room temperature
- 1 tablespoon pure vanilla extract
Whisk together flour, sugar, and salt in a medium bowl. Whisk together milk, eggs, and vanilla in another medium bowl. Gradually add milk mixture to flour mixture, whisking until smooth. Add chocolate-butter mixture, whisking until smooth. Pour through a fine sieve into an airtight container; discard lumps. Refrigerate at least 2 hours or up to overnight.
Lightly coat an 8-inch crepe pan or nonstick skillet with melted butter. Heat over medium heat until just starting to smoke. Remove pan from heat; pour about 2 tablespoons batter into pan, swirling to cover bottom. Reduce heat to medium-low; return pan to heat. Cook, flipping once, until edges are golden and center is dry, about 30 seconds per side. NOTE: I don’t have a non-stick skillet or a crepe pan and making crepes that are flippable is really sloppy without these items. Since i was making them for a brunch I made mini ones and used my largest biscuit cutter on an enamelware skillet and stacked them on 7 layers high. This made 7 servings using the portions of this recipe so you could half the recipe if you want to make fewer. They made for a nice presentation & were easy to serve just quartered.
Slide crepes onto a plate. Repeat process with remaining batter, coating pan with butter as needed. Crepes can be refrigerated, covered, up to 1 day.
Chocolate Glaze:
Makes about 2 cups
- 1 1/4 cups heavy cream
- 1 tablespoon light corn syrup
- Pinch of salt
- 10 ounces semisweet chocolate, finely chopped
Hazelnut Creme Filling:
- 4 egg whites
- ¾ cup sugar
- pinch cream of tartar
- 3 sticks butter
- 1 11 oz can Hazelnut Praline (Love n’ Bake is the brand I use, if you can’t find amazon sells it, one less step OR see following Hazelnut Praline recipe to make your own recipe of it, which is less than the canned but just as hazelnutty since it’s fresh)
Place the bowl on the mixer with the whip attachment. Add cream of tartar and whip on medium high speed until the whites form stiff peaks. Add the softened butter a few tablespoons at a time, scraping the bowl frequently. Whip until the buttercream is smooth and fluffy.
Hazelnut Praline:
Makes about 1 cup
- 1 cup (5 ounces) hazelnuts
- Canola oil, for pan
- 2 cups sugar
- 1 1/2 tablespoons freshly squeezed lemon juice
In a medium saucepan, combine sugar and lemon juice. Cook over medium heat, brushing down sides of pan with a damp pastry brush to remove any sugar crystals that may form, until mixture is amber, about 9 minutes; do not stir. (Pan may be swirled gently about halfway through to incorporate any uncooked sugar.) Pour directly over nuts to create a thin layer. Set aside to cool, at least 30 minutes.
Place half the praline in the bowl of a food processor; process until the praline is very fine with no sharp pieces. Cut the remaining praline into small pieces for decoration. Praline may be made up to 1 week ahead and kept in an airtight container, at room temperature.
Assembly:
Place a crepe on a wire rack set over a rimmed baking sheet or wax/parchment paper. Spread with a thin ⅛ inch layer hazelnut filling. Top with another crepe. Continue layering with hazelnut filling and crepes, using about 32 crepes and ending with a crepe on top. If making smaller stack to 7. Refrigerate until firm, about 15 minutes.
Spoon glaze on top of the cake, spreading to edges. Spread remaining glaze around sides of cake, coating completely. Refrigerate until glaze is firm and set, about 20 minutes. Cake can be refrigerated up to 3 days.
