Step 1: Prepare Pecans
Preheat oven to 350°F and lightly oil a rimmed baking sheet.
Toss pecans with maple syrup, sugar, and miso until well coated.
Spread evenly on the baking sheet and bake for 6–8 minutes until fragrant. Let cool.
Step 2: Prepare Cake Batter
Grease a 9"-diameter cake pan with butter and line with parchment paper.
Whisk eggs, sugar, and salt until smooth. Add coconut milk, vanilla, and melted butter; whisk well.
Gradually whisk in mochiko and baking powder until the batter is smooth and thick. Pour into the pan.
Step 3: Assemble and Bake
Scatter cooled pecans evenly over the batter.
Bake for 50–55 minutes, until the top is golden and a tester comes out clean.
Cool in the pan for 15 minutes, then turn out onto a rack. Let cool completely.
Step 4: Serve Slice and serve with vanilla ice cream for a perfect pairing.
