Instructions

1. 1

   Preheat your oven to 375°F (190°C) and lightly grease an 8-inch square baking dish.

2. 2

   In a small saucepan, combine the maple syrup, heavy cream, and 2 tablespoons of the butter. Bring to a gentle boil over medium heat, stir for 2 minutes, then remove from heat.

3. 3

   In a large mixing bowl, cream the remaining butter and granulated sugar together until light and fluffy.

4. 4

   Beat in the egg and vanilla extract until smooth.

5. 5

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

6. 6

   Add the dry ingredients to the butter mixture alternately with the milk, starting and ending with the flour. Stir until just combined, then fold in the chopped walnuts.

7. 7

   Pour the hot maple sauce into the prepared baking dish.

8. 8

   Spoon the cake batter evenly over the hot sauce. Do not stir the batter into the sauce; it will rise to the top as it bakes.

9. 9

   Bake for 35 to 40 minutes, or until the cake is golden brown and a toothpick inserted into the center of the sponge comes out clean.

10. 10

    Let cool for 10 minutes before serving warm to allow the sauce to thicken slightly.
