This vegan, grain- and gluten-free chocolate hazelnut tart is excellent whether you have dietary restrictions or not. Using a hazelnut cookie as the base was inspired by a reader, who took my gluten-free peanut butter cookies and made a tart with that dough as a base a while back.
It’s made with coconut flour and maple syrup for a really simple press-in tart shell. The base is more chewy than crisp, but the edge bits are a bit snappy. Filled with vegan chocolate ganache (made with coconut milk) it’s an elegant, easy dessert.
The tart isn’t particularly large. It’s very rich, with the chocolate truffle filling and hazelnut base, so you just need a small piece. I took these photos during currant season, and a touch of acidity from fruit helps to cut through the richness. In wintertime, citrus is good, as in this chocolate orange tart, or persimmon, or frozen berries.
Ingredient Notes and Substitutions
- Hazelnut butter: while hazelnut is a great combination, you could also use almond or peanut butter, or sunflower seed butter for a nut-free option.
- Coconut milk: this must be full-fat milk, from a can. Low fat or light coconut milk won’t work for this recipe.
- Dark chocolate: the chocolate for the ganache should be at least 65% cocoa solids, so use a good dark chocolate. Anything less and it won’t set properly.
Note that depending on the consistency of your nut butter, you might have to add an extra splash of milk. Use runny hazelnut butter if you can instead of the hard bit at the bottom of the jar.
The trick to a good ganache is never to heat the chocolate, just the milk. It’s also much better with bar chocolate instead of chips, which have a stabilizer added so they don’t melt easily.
If the dough base is too soft, first let it sit for 5 minutes and see if it thickens. If not, add another tablespoon of coconut flour and stir for another 30 seconds to incorporate and thicken. Coconut flour varies in consistency and you may need slightly more or less depending on the type – but you’re going for a flexible ball of dough.
How to Store
Storage: the tart is best on the day it’s made and does soften slightly when stored. It can be kept in the refrigerator in a sealed container for up to three days.
Freezing: this can be frozen if necessary, but the texture changes for the worse after thawing if frozen solid. I don’t recommend it.
- Set quickly: to make the filling set more quickly, freeze the tart for half an hour before refrigerating until the ganache is set (solid enough to slice).
- Remove the tin base easily: freeze for 15 minutes, then pop the base off with a butter knife or spatula. If you tend to have trouble with your pan sticking, cut a round of parchment paper to place in the bottom before adding the dough.
- Sweeten to taste: if you have a real sweet tooth, you can add some more maple syrup to the filling, 1-3 tablespoons. Taste the ganache before pouring it into the tart to check.
