Korean Hodu-gwaja, Walnut Cakes
Hodu-gwaja are bite-size, walnut-shaped cakes with a piece of walnut baked inside, sold warm in paper bags at train stations and highway rest stops. This keto version uses an almond-flour batter and a sweet cream cheese filling in place of red bean paste. A cake-pop maker or mini muffin tin works if you do not have walnut molds.
