Ingredients

Base Dough

300 g Japanese sweet potato paste strained
30 g unsalted butter Yotsuba, Kerrygold, or standard unsalted butter
50 g sugar Organic cane sugar, light brown sugar, or granulated sugar
1 egg yolk
1 tsp vanilla bean paste
10 g heavy cream 35% pure cream

Optional Flavor Boosters

1 tsp dark rum or brandy
1/8 tsp ground cinnamon
1 pinch freshly grated nutmeg

Egg Wash & Topping

1 egg yolk whisked with 1/2 tsp water if needed
Black sesame seeds optional, for garnish

Instructions

In a heavy-bottomed saucepan off the heat, combine the 300g sweet potato paste, 30g unsalted butter, 50g sugar, 1 egg yolk, and 1 tsp vanilla bean paste (plus optional rum or spices).
Whisk or stir with a rubber spatula until fully smooth and emulsified, then turn the burner on to low heat to gently warm the mixture through.
Stir in the 10g heavy cream. Place the pot back over medium-low heat. Cook continuously with a rubber spatula, scraping the bottom and sides in a sweeping motion to prevent scorching.
Cook until the paste holds firm, shows clear spatula lines (anko strokes), and takes about 5 seconds to drop from the spatula.
Transfer the hot cooked paste to a container, spread it flat, and cover it (touching the surface to prevent condensation). Place in the refrigerator for 1 hour (or in the freezer for 20–30 minutes) until fully chilled and non-sticky.
Scale the chilled paste into small portions of 23g to 25g each. Roll each portion between your palms into any shape you like—classic mini footballs/boats, hearts, rounds, or cubes.
Arrange the shapes on a parchment-lined baking sheet and brush the tops evenly with egg yolk wash (and sprinkle black sesame seeds on top if using).
Bake in a preheated oven at 460°F (240°C) for 3 minutes, then turn on the broiler for 1 to 2 minutes until the tops develop a glossy, deep golden caramelization. (If using a toaster oven, bake on high for 4 to 6 minutes, watching closely after 3 minutes)

Notes

Sweet Potato Prep: If making paste from scratch, slow-bake satsumaimo (such as Beni Haruka or Silk Sweet) at 325°F (160°C) for 1 hour 45 minutes for maximum sweetness, peel while warm, and pass through a fine sieve or ricer.
Moisture Control: Because different sweet potato varieties vary in water content, add heavy cream gradually. If your paste is already soft, hold back the cream.
Toaster Oven Friendly: You don't need a commercial oven! A standard toaster oven works wonderfully for these mini shapes.
Storage & Freezing: Store in an airtight container in the refrigerator for up to 3 days (tastes delicious chilled!). Alternatively, freeze shaped/baked pieces for up to 1 month and thaw at room temperature for 15 minutes before enjoying.
