Are you talking about fried pastry filled with chocolate?
If so I have had better luck using a italian recipe for dough
2 pounds of ap flour, 2 whole eggs, 1/4 pound of unsalted butter,
2 cups white wine, 2 tablespoons baking powder.
Melt butter and Wine gently, Combine dry ingredients. Put dry ingredients
on table and form well. Mix slighly cooled wine butter mixture with eggs.
Pour into well and incorporate like you would while making pasta dough.
Work dough thoroughly while being careful not to overwork it. Let dough
rest in refri for 2 ours, then roll out with pasta maker as you would to make
ravioli. I fill with straight bittersweet chocolate or an extra firm ganache.
Form churro or ravioli shapes and fry at 350 degrees for 2 to 3 minutes.
Garnish with powder sugar and plate. Its a good alternative. These churros
will last up to two days uncooked in refrigerator. Great filled with Raspberries,
lemon zest, and raspberry jam. Also sweetened Mascarpone and chocolate.
