White Chocolate Blondie Sundaes are soft, chewy blondies topped with vanilla ice cream and drizzled with a dreamy Maple Sauce. This dessert is simple enough for weeknights, impressive enough for serving to guests, and an excellent make-ahead/freezer option.

Many years ago our family went to Applebee’s for dinner and ate one of the best desserts we had ever had… Butter Pecan Blondie Sundaes. The components are very simple - a blondie with white chocolate chips, vanilla ice cream, and a maple caramel sauce. When you put the three together it’s like fireworks in your mouth - incredibly delicious!
Since then, we have been making our own version of the Applebee’s blondie based on a knockoff version from All Recipes (the recipe is no longer available online). We adjusted the recipe to make the perfect thickness of blondie, and then added heavy cream to the original maple sauce recipe to make it lighter.
🍨 Ingredients
Flour: All-purpose, white flour.
Baking powder: Helps the blondies rise.
Baking soda: Works with the baking powder to help the blondies rise.
Salt: Kosher salt is best.
Butter: Salted is preferred, but unsalted is fine, too.
Brown sugar: Light brown sugar is preferred, but dark can be used.
Eggs: Bring them to room temperature before baking for best results.
Vanilla: One of the main flavors in this recipe. Don’t skip the vanilla.
White chocolate chips: My favorite brand is Ghirardelli, but any brand will do.
Walnuts: You can opt to leave the nuts out, but they add great texture and flavor.
Maple syrup: Use real maple syrup, not artificial flavoring.
Heavy cream: This will lighten the maple caramel sauce and give it the perfect consistency.
🥣 Instructions
Start the blondie batter by whisking the dry ingredients in a small bowl and setting it aside. In a large bowl, beat the brown sugar with melted butter. Once combined, add the eggs and beat until the mixture is smooth, thick, and glossy. Add half of the dry ingredients and mix on low until just combined, then repeat with the remaining dry ingredients. Once the batter is formed, mix in the white chocolate chips and walnuts. Press into a prepared 9x13 baking pan and bake at 350°F for 35-40 minutes.
While the blondies are baking, make the maple sauce. Simply combine the maple syrup, brown sugar, butter, and vanilla in a microwave-safe dish and microwave on high for 1.5-2.5 minutes, stirring every 30 seconds. Continue cooking in the microwave until the sugar is fully dissolved. Then add the heavy cream and vanilla, and stir until combined.
👨👩👧👦 For a Crowd
White Chocolate Blondie Sundaes with Maple Sauce are an excellent crowd dessert! You can double the recipe and make two 9x13 pans, or you can make one recipe and cut the blondies smaller to match the size of your crowd. If you want to make them ahead for a party, both the blondies and sauce freeze beautifully. See my freezer notes in the Question and Answers section.
🙋 Questions and Answers
Blondies are done when the top is golden brown and a toothpick inserted in the middle comes out clean or with fudgy crumbs attached. For moist blondies, don’t overbake!
Wait to cut blondies until they are completely cool. For the straightest cutting, refrigerate them until cold and then cut with a very sharp knife.
