Here's a step-by-step guide to making them.

In a mixing bowl, whisk together the flour, sugar, baking powder, and salt.

In another bowl, whisk the egg with milk, melted butter, and vanilla extract until well combined.

Pour the wet ingredients into the dry ingredients and stir gently until just combined, leaving the batter slightly lumpy.

Preheat a non-stick skillet over medium-low heat and lightly grease with butter or oil.

Pour 1/4 cup batter onto the skillet, spread into a round shape, cook until bubbles form and edges set, flip, and cook until golden brown, then repeat.

Cool the cooked pancakes slightly on a plate to help them hold their shape when filled.

Stir store-bought red bean paste or ensure homemade paste is smooth and not runny.

Spread red bean paste on one pancake, top with another pancake, and press lightly to make a sandwich.

Serve Dora Cakes warm or at room temperature; they can be enjoyed immediately or stored in an airtight container.

For a finishing touch, dust with powdered sugar or drizzle with honey, and serve with fresh fruit or tea.
