Electric Mixer

If you want to make any holiday cookie, this is your dough: Just add your choice of mix-ins to create endless delicious variations.

Powdered green tea gives these tender cookies an elf-worthy hue that will stand out, with no icing or decorating needed.

These pretty (gluten-free!) butter cookies come in three flavors: lime, lemon, and grapefruit. Or just pick one variety and triple the amount of zest and juice. You'll find psyllium-husk powder, flax seed, chia seed, and rice-based gluten-free flour at most natural foods stores.

Rich, sweet, moist and yet completely free from flour and refined sugar, this Italian lemon and almond cake is a great way to end a meal. It is technically a cheesecake, but has very little in common with the heavy American versions. In Italy, most delis have their own version of ricotta. The most delicious one is made from sheep's milk–try it in this recipe, if you can find it. We often prepare the cake a day in advance. It makes it even creamier and enhances the flavors.

One of the most important steps in making custard is making sure the sugar is fully dissolved into the yolks. Be sure to beat them together until pale yellow ribbons form, since the sugar acts as a shield for the yolks, preventing them from curdling when you add the hot cream.

Light, pretty, festive, and special, this can pull off the trick of being either the Christmas Yule log (without the chocolate or the sponge) or the perfect pudding for a midsummer lunch.

As much as I like a pavlova, this dessert takes that classic combination and blows it out of the water. Piña Colada Pastry Cream lightened with softly whipped cream, layered with caramelized fresh pineapple, crunchy-chewy French meringue, and crisp strips of toasted coconut is textural nirvana. Searing fresh pineapple in a skillet adds caramel flavor to balance very sweet fruit. This is a showstopper.

There are many stories about the origins of this cake, known as both Clichy cake and Opéra cake. Many believe that Louis Clichy was its creator because he premiered the gâteau, with his name written across the top, at the 1903 Exposition Culinaire in Paris. It became the signature cake of Clichy's shop on the Boulevard Beaumarchais. However, another pastry shop, Dalloyau, sold a very similar dessert, known as L'Opéra (in honor of the Paris Opera), and some claim that theirs was the original.

I've done some crazy, unconventional things in baking, but using avocados in place of butter may just be the craziest. Believe it or not, it works! For these chewy cookies made with chunks of chocolate and walnuts in every bite, I use absolutely no butter. They taste too good to be light—and you can't detect the taste of avocados at all. I tested these out on many unsuspecting adults, children, and teens, and everyone loved them. Karina, my college-age daughter, was the ultimate test—she's a true chocoholic. She thinks they're pretty awesome!

We make the shells for these tarts with packaged graham cracker crumbs to save time. If your brown sugar contains hard lumps, force it through a sieve before using. Otherwise, it won't dissolve in the filling.

Cakey on top, pudding-y on the bottom, tart all the way through.

If you can find candied chestnuts, simply toss them in the cocoa with one tablespoon of brown sugar (no need to glaze them first).

The caramelized milk jam makes for a decadent little sandwich, but these cookies are amazingly good simply eaten on their own.

Use store-bought meringues and skip the first step, if you prefer.

To check if your meringue is stiff, lift the beaters out of the bowl and upend them: The peaks should stick straight up.

Choose a mild, not-too-peppery olive oil for this tender cake; something fruity will complement the lemony sweetness, but an assertively bitter oil will overwhelm.
