How to make Crumbl Cookie Brownie Sundae

The Crumbl Cookie Brownie Sundae is a popular dessert that combines elements of a brownie and a sundae, typically featuring a warm, fudgy brownie base topped with scoops of vanilla ice cream, drizzles of chocolate sauce, whipped cream, and often garnished with toppings like nuts or sprinkles.

Ingredients:

Brownie Base:

  • 1/2 cup unsalted butter, melted
  • 1 cup granulated sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1/3 cup unsweetened cocoa powder
  • 1/2 cup all-purpose flour
  • 1/4 teaspoon salt
  • 1/4 teaspoon baking powder

Vanilla Mousse:

  • 1 cup heavy whipping cream
  • 2 tablespoons confectioners’ sugar
  • 1 teaspoon vanilla extract
  • 1/2 cup cold whole milk
  • 1 box (3.4 oz) instant vanilla pudding mix

Sundae Toppings:

  • Warm fudge sauce
  • Rainbow sprinkles
  • Maraschino cherries with stems

Instructions:

For the Brownie Base:

  1. Preheat your oven to 350°F (175°C). Grease a 9×9 inch baking pan or line it with parchment paper.
  2. In a medium bowl, mix the melted butter, sugar, eggs, and vanilla extract until well combined.
  3. Sift in the cocoa powder, flour, salt, and baking powder. Stir until just combined; do not over-mix.
  4. Spread the batter evenly into the prepared pan.
  5. Bake for 20 to 25 minutes or until a toothpick inserted in the center comes out with a few moist crumbs.
  6. Remove from the oven and let cool completely in the pan on a wire rack.

For the Vanilla Mousse:

  1. In a bowl, whisk together the milk and vanilla pudding mix until smooth.
  2. In a separate bowl, beat the heavy whipping cream with the confectioners’ sugar and vanilla extract until stiff peaks form.
  3. Gently fold the whipped cream into the pudding mixture until no streaks remain, creating a light and fluffy mousse.

Assembling the Sundae:

  1. Once the brownie has cooled, cut it into squares. These will serve as the base of your sundaes.
  2. Place a brownie square at the bottom of each serving dish.
  3. Dollop a generous amount of vanilla mousse over the brownie.
  4. Warm up the fudge sauce for a few seconds in the microwave, ensuring it’s pourable but not too hot.
  5. Drizzle the warm fudge sauce over the mousse-topped brownie.
  6. Sprinkle rainbow sprinkles over the top to capture that whimsical sundae feel.
  7. Top each sundae with a maraschino cherry for the quintessential finishing touch.

Tips for Making the Perfect Crumbl Cookie Brownie Sundae:

  • Quality Ingredients: Use high-quality cocoa powder and natural vanilla extract for the best flavor.
  • Brownie Doneness: Do not overbake the brownies. They should be moist and fudgy for the perfect sundae base.
  • Chill the Mousse: For best results, chill the mousse for at least an hour before assembling the sundaes. This will make it easier to work with and hold its shape better on the brownie.
  • Warm and Gooey: Heat the fudge sauce just before serving to ensure a delectable contrast between the cool mousse and the warm fudge.
  • Sprinkles and Cherry: Don’t skip on these, as they add to that classic sundae appearance and give a little extra texture and flavor.

What to serve with

Creating a complete dessert experience around the decadent Crumbl Cookie Brownie Sundae involves a thoughtful selection of complementary items. These choices can elevate the entire meal and provide a balanced and fulfilling dessert for your guests or family.

1. Beverages:

  • Coffee: Offering a selection of freshly brewed coffee, including decaf and espresso, can complement the sweetness of the sundae with its rich, bitter notes, creating a satisfying contrast.
  • Milk: Cold milk, whether whole, 2%, or a non-dairy alternative, is a classic pairing with chocolatey desserts. It helps cleanse the palate and enhances the chocolate flavors.
  • Dessert Wines: A sweet dessert wine like Port, Sherry, or a late-harvest Riesling can pair beautifully with the chocolate and vanilla flavors, providing an elegant touch to your dessert course.

2. Fruit Accompaniments:

  • Fresh Berries: A side of fresh berries, like strawberries, raspberries, or blueberries, adds a tart contrast to the sweet sundae, making each bite more refreshing.
  • Grilled Pineapple or Peaches: For a summer twist, serve grilled pineapple slices or peaches alongside the sundae. The caramelization from grilling enhances the fruit’s sweetness and complements the sundae’s rich flavors.

3. Bite-Sized Desserts:

  • Mini Cheesecakes: Offering bite-sized cheesecakes alongside the sundae provides a creamy, tangy contrast that cuts through the sundae’s richness.
  • Macarons or Petit Fours: These small desserts are visually appealing and their delicate flavors can offer a light, sweet complement without overpowering the main attraction.

4. Light Baked Goods:

  • Scones or Biscotti: Scones or biscotti, especially when flavored with citrus or almond, can add a textured, slightly less sweet element that complements the creamy, chocolaty sundae. They’re also perfect for dipping into coffee.
  • Angel Food Cake: A light, fluffy angel food cake can be a delightful addition, offering a soft and airy contrast to the dense, rich brownie base of the sundae.

5. Nut and Cheese Platter:

  • Assorted Nuts and Cheeses: A platter of assorted nuts and cheeses can add a sophisticated touch to your dessert spread. The creaminess of the cheeses and the crunch of the nuts provide a delightful texture and flavor contrast to the sundae.

Ingredients Substitutes

Creating a Crumbl Cookie Brownie Sundae involves marrying the rich textures and flavors of cookies, brownies, ice cream, and optionally toppings like syrups, whipped cream, and nuts.

Cookie and Brownie Base

  • Flour: For a gluten-free version, use almond flour, coconut flour, or a gluten-free all-purpose flour blend instead of regular all-purpose flour.
  • Butter: Unsalted butter can be replaced with coconut oil, vegan butter, or margarine for dairy-free or vegan options. For a healthier substitute, applesauce can sometimes be used, especially in brownies, though this may affect texture.
  • Eggs: To make your cookies and brownies without eggs, options include apple sauce (1/4 cup per egg), mashed banana (1/4 cup per egg), or commercial egg replacers. Ground flaxseeds mixed with water (1 tablespoon flaxseed to 2.5 tablespoons water, set aside for 5 minutes) can also work as a binder.
  • Sugar: If you’re avoiding white sugar, coconut sugar, maple syrup, or honey can be good alternatives, though liquid sweeteners may affect the consistency.

Ice Cream

  • Dairy-Free Alternatives: There are numerous dairy-free ice creams available made from almond milk, coconut milk, soy milk, or oat milk, suitable for vegans or those with lactose intolerance.
  • Flavor Variations: Instead of vanilla, feel free to use any flavor that complements the chocolatey base, such as caramel, strawberry, or mint chip.

Toppings

  • Whipped Cream: Vegan whipped cream is available in most health food sections, or you can make your own using coconut cream. Simply refrigerate a can of full-fat coconut milk, scoop out the solidified cream, and whip with a bit of powdered sugar.
  • Syrups and Sauces: For healthier alternatives to chocolate or caramel syrup, pureed fruit, like raspberries or mango, can add a natural sweetness and vibrant color. There are also sugar-free syrups available.
  • Nuts and Extras: For nut allergies, seeds like pumpkin or sunflower can add crunch, or you can opt for allergy-friendly brands of chocolate chips or sprinkles.

Final Thoughts

Enjoy your homemade Crumbl Cookie Brownie Sundae, a fitting tribute to the crowd-pleasing original, and now a dessert you can say is truly your creation.
