Blondie

Oat Streusel

Rum-Toffee Sauce

Method

Blondie

  1. 1

    Preheat the Oven

    Preheat your oven to 350°F (175°C). Grease a 9x13 inch baking pan.

  2. 2

    Make the Blondie Batter

    In a large bowl, melt the unsalted butter. Stir in brown sugar and granulated sugar until well combined. Add in eggs and vanilla extract, mixing until smooth.

  3. 3

    Combine Dry Ingredients

    In another bowl, whisk together flour, baking powder, and salt. Gradually add the dry ingredients to the wet mixture until just combined.

  4. 4

    Fold in Mix-ins

    Gently fold in the toasted pecans, coconut flakes, and butterscotch chips.

  5. 5

    Bake

    Spread the batter into the prepared baking pan and bake for 25-30 minutes or until a toothpick inserted in the center comes out clean. Allow to cool slightly.

Oat Streusel

  1. 6

    Prepare the Streusel

    In a medium bowl, combine rolled oats, flour, brown sugar, and cinnamon. Melt the unsalted butter and mix it into the dry ingredients until crumbly.

  2. 7

    Bake the Streusel

    Spread the streusel mixture on a baking sheet and bake at 350°F (175°C) for about 10-12 minutes, stirring halfway, until golden brown.

Rum-Toffee Sauce

  1. 8

    Cook the Sauce

    In a saucepan over medium heat, combine heavy cream, brown sugar, and unsalted butter. Stir until the mixture comes to a simmer and the sugar is dissolved.

  2. 9

    Add Rum

    Remove from heat and stir in the dark rum. Set aside to cool slightly.

To Serve

  1. 10

    Assemble the Sundae

    Cut the warm blondie into squares and place in bowls. Top with scoops of vanilla ice cream.

  2. 11

    Add Toppings

    Sprinkle the oat streusel over the ice cream and blondie. Finish with white chocolate shavings.

  3. 12

    Pour the Sauce

    Warm the rum-toffee sauce if needed, then pour it over the sundae tableside for a delightful presentation.
