Follow these simple steps to create your Toasted Black Sesame & Miso Caramel Cake:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Grease and flour a 9-inch round cake pan.
2. Prepare Black Sesame: In a skillet over medium heat, lightly toast the black sesame seeds until fragrant, about 4-5 minutes. Let them cool.
3. Mix Dry Ingredients: In a bowl, sift together the flour, baking powder, baking soda, and salt. Add the cooled toasted black sesame seeds and mix well.
4. Cream Butter and Sugar: In a large mixing bowl, cream the softened butter and granulated sugar until light and fluffy.
5. Add Eggs: Beat in the eggs one at a time, ensuring each is fully incorporated before adding the next.
6. Combine Wet Ingredients: Mix in the milk and vanilla extract to the butter-sugar mixture until well combined.
7. Combine Mixtures: Gradually add the dry ingredients to the wet mixture, stirring until just combined. Do not overmix.
8. Prepare Miso Caramel: In a saucepan, combine brown sugar and water over medium heat. Cook until the sugar dissolves and turns a deep amber color. Remove from heat and carefully stir in the heavy cream and miso paste until smooth.
9. Bake the Cake: Pour the batter into the prepared cake pan and bake for 40-45 minutes or until a toothpick inserted in the center comes out clean.
10. Cool the Cake: Remove the cake from the oven and let it cool in the pan for 15 minutes. Transfer to a wire rack to cool completely.
11. Glaze the Cake: Once cooled, drizzle the miso caramel sauce over the top of the cake, allowing it to drip down the sides.
