Why Make This Maple Walnut Blondie Sundae Recipe
This recipe is the perfect balance of textures and temperatures. The blondie itself is dense and fudgy, providing a sturdy base for the melting ice cream. Unlike traditional chocolate brownies, the brown sugar in the blondie creates a deep butterscotch flavor that complements the maple syrup perfectly. It is an excellent alternative for those who want a break from chocolate-heavy desserts.
Making this sundae at home allows you to control the quality of the ingredients. You can toast your walnuts to perfection and use real maple syrup for a rich, authentic taste that store-bought toppings simply cannot match. Plus, it is incredibly versatile and easy to scale up if you are feeding a crowd.
How to Make Maple Walnut Blondie Sundae Recipe
Creating this masterpiece is a straightforward process that involves baking a quick batch of blondies and preparing a simple yet delicious maple glaze while they cool. Follow these easy steps to bring this restaurant-quality dessert to your kitchen table.
Ingredients
- 1/2 cup unsalted butter, melted and slightly cooled
- 1 cup packed light brown sugar
- 1 large egg, room temperature
- 1 teaspoon pure vanilla extract
- 1 cup all-purpose flour
- 1/2 teaspoon salt
- 3/4 cup chopped walnuts, toasted
- 1/2 cup pure maple syrup
- 2 tablespoons unsalted butter (for the sauce)
- 1/4 cup heavy cream
- Vanilla bean ice cream, for serving
- Whipped cream and extra walnuts for garnish
Directions
Step 1: Preheat and Prepare
Preheat your oven to 350°F (175°C). Grease an 8×8-inch square baking pan or line it with parchment paper, leaving an overhang on the sides for easy removal of the blondies.
Step 2: Mix Wet Ingredients
In a large mixing bowl, whisk together the melted butter and brown sugar until smooth. Add the egg and vanilla extract, beating until the mixture is well combined and slightly glossy.
Step 3: Combine Dry Ingredients
Gently fold in the flour and salt using a spatula. Be careful not to overmix, as this can make the blondies tough. Once the flour is mostly incorporated, stir in 1/2 cup of the toasted walnuts.
Step 4: Bake the Blondies
Spread the batter evenly into the prepared baking pan. Bake for 20 to 25 minutes, or until the edges are golden brown and a toothpick inserted into the center comes out with a few moist crumbs. Allow them to cool in the pan for at least 15 minutes.
Step 5: Prepare the Maple Sauce
In a small saucepan over medium heat, combine the maple syrup and 2 tablespoons of butter. Bring to a light simmer for 3 minutes. Remove from heat and whisk in the heavy cream until smooth and thickened. Set aside to cool slightly.
Step 6: Assemble the Sundaes
Cut the warm blondies into squares. Place one square in a bowl, top with a generous scoop of vanilla ice cream, and drizzle with the warm maple sauce. Garnish with whipped cream and the remaining walnuts.
How to Serve Maple Walnut Blondie Sundae Recipe
The best way to serve this dessert is while the blondies are still slightly warm. This allows the ice cream to melt just enough to create a creamy sauce that mingles with the maple drizzle. For an extra touch of elegance, serve them in glass dessert goblets or wide shallow bowls. You can also add a tiny pinch of flaky sea salt over the top to enhance the maple and walnut flavors.
How to Store Maple Walnut Blondie Sundae Recipe
Store any leftover blondies in an airtight container at room temperature for up to 3 days or in the refrigerator for up to a week. The maple sauce should be stored in a glass jar in the refrigerator. When you are ready for another sundae, simply reheat a blondie square in the microwave for 15 seconds and warm the sauce gently on the stove or in the microwave before assembling.
Expert Tips for Perfect Maple Walnut Blondie Sundae Recipe
To get the best results, always toast your walnuts before adding them to the batter. Just 5 minutes in a dry pan over medium heat will significantly deepen their flavor. Also, make sure not to overbake the blondies; they should still look slightly soft in the middle when you take them out of the oven to ensure a fudgy texture. Lastly, use Grade A dark maple syrup for the sauce to get the most robust maple flavor possible.

Delicious Variations
If you want to change things up, try swapping the walnuts for pecans or macadamia nuts. For a “loaded” version, add 1/2 cup of white chocolate chips or butterscotch chips to the blondie batter. If you prefer a bit of spice, a pinch of cinnamon or nutmeg in the dry ingredients pairs beautifully with the maple syrup. For a boozier treat, stir a tablespoon of bourbon into the maple sauce after removing it from the heat.
Frequently Asked Questions
Q: Can I make this recipe gluten-free?
Yes, you can substitute the all-purpose flour with a 1:1 gluten-free baking flour blend. The texture may be slightly different, but it will still be delicious.
Q: What is the difference between a brownie and a blondie?
Brownies rely on cocoa powder or melted chocolate for flavor, while blondies use brown sugar and vanilla to create a caramel or butterscotch flavor profile.
Q: Can I freeze the blondies?
Absolutely! Wrap individual blondie squares tightly in plastic wrap and store them in a freezer-safe bag for up to 3 months. Thaw at room temperature before serving.
Q: Does the maple sauce harden?
The sauce will thicken as it cools, but it stays pourable. If it gets too thick in the fridge, just microwave it for a few seconds to loosen it up.
Q: Can I use pancake syrup instead of maple syrup?
It is not recommended. Pancake syrup is mostly corn syrup and lacks the depth of flavor needed for the sauce. Use 100% pure maple syrup for the best results.
