Creating this Miso Caramel Blondie Sundae can be straightforward. Follow these steps to achieve a delicious result:

For the Blondies

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease and line a 9×13-inch baking pan with parchment paper.

2. Melt Butter: In a mixing bowl, combine the melted butter and brown sugar. Stir until smooth.

3. Add Eggs and Vanilla: Add the eggs one at a time, mixing well after each addition. Then add the vanilla extract and mix until combined.

4. Combine Dry Ingredients: In a separate bowl, whisk together the flour, baking powder, and salt.

5. Merge Mixtures: Gradually add the dry ingredients to the wet mixture. Stir until just combined; be careful not to overmix.

6. Add White Chocolate Chips: Fold in the white chocolate chips until evenly distributed.

7. Transfer to Pan: Pour the blondie batter into the prepared baking pan, smoothing the top with a spatula.

8. Bake: Bake in the preheated oven for 25-30 minutes, or until a toothpick comes out clean from the center.

9. Cool: Remove from the oven and allow blondies to cool in the pan before transferring to a wire rack.

For the Miso Caramel Sauce

1. Combine Sugar and Heat: In a saucepan, heat granulated sugar over medium heat until it melts and turns a deep amber color. Stir frequently to prevent burning.

2. Add Butter: Once the sugar is fully melted, carefully add the butter. Be cautious of steam and bubbles.

3. Pour in Cream: Once the butter is combined, slowly pour in the heavy cream while stirring continuously.

4. Add Miso: Remove the saucepan from heat and add the miso paste. Whisk until completely incorporated.

5. Season: Add a pinch of salt to balance the sweetness and mix well. Allow the sauce to cool slightly before using.
