I'm looking for an impressive Valentine's Day dessert to make without a mixer!

A creme burelle is good if you have a blow torch and custard dishes.

Lemon posset with a blueberry sauce or Deb Perlman has a wonderful dessert with raspberries covered with sour cream, brown sugar and run under the broiler to brûlée. Happy dining!

For my anniversary I made dessert from 2 recipes on this site, neither of which requires a mixer: https://food52.com/recipes/9338-zabaglione-al-caffe served in little cappuccino cups with https://food52.com/recipes/23153-biscotti-di-vino.

This chocolate "mousse" - posted yesterday -- looks marvelous. https://food52.com/recipes/75482-maria-speck-s-greek-yogurt-chocolate-mousse

I know you asked for "impressive" and "gorgeous." To me, if it tastes delicious and is not something served in any of your favorite restaurants, then it meets the "impressive" test. As for gorgeous, well, this kind of beauty is in the eye of the beholder. It would certainly qualify as "gorgeous" to me.

That said, I can see how marmalade on top might not necessarily be received in every case with the kind of enthusiasm one might want, so one could get some frozen raspberries and cook half of them down with some sugar to make a quick jam; stir a few intact berries in at the end, and then drizzle that over the mousse right before serving . . . . . or you could made a light caramel sauce and sprinkle Maldon salt + toasted pecans on it, for a "mousse" sundae . . . . . or serve it in a pool of rum-spiked espresso, with a sprinkling of finely chopped roasted macadamia nuts, or some delicate, buttery, homemade cookies alongside in the bowl . . . . I can think of so many possibilities.

Let us know, please, what you do! Thank you. ;o)

Along the lines of chocolate covered strawberries, here is a link for easy-to-make chocolate bowls (there's even a video!). https://tipbuzz.com/chocolate-balloon-bowls/

You can artfully pile up your pretty dipped berries--chocolate dipped red grapes are delicious also--in the bowls, or use them to serve really good quality ice creams or sorbets with favourite toppings.

So easy...chocolate covered strawberries. Aren’t they one of ‘official’ indulgence for Valentines Day? 💕

Icebox Cake!! There's whipped cream involved, but that can be done by hand or with a hand-mixer. Plus it's so light and fluffy and delicious. I love doing it with the chocolate wafers and add in some fresh fruit like strawberries or raspberries. https://food52.com/blog/7061-how-to-make-any-icebox-cake-in-5-steps

@Taylor Singer, you don't really need a stand mixer (aka Kitchen Aid), if that's what you are talking about. Regular handheld electric beaters will work and a good one will cost ~$20. It's what I used growing up because we didn't bake that much and couldn't afford a KA back then :)

My suggestion for a truly luxurious and impressive Valentine's Day dessert is Coeur a la Creme. No baking required. Here's a fairly straight forward recipe: https://www.bonappetit.com/recipe/coeur-a-la-creme

You can use yogurt cups as molds. Looks very fancy and tastes like a million bucks.

Or make frozen berries with a hot chocolate sauce: https://communitytable.parade.com/296674/dash/frozen-berries-with-hot-white-chocolate-sauce/

Pots de creme.

Chocolate mousse made with avocado.
Or tiramisu (not so much in fashion, but a classic for a reason.
Chill overnight.
