How to Prepare Chocolate Chip Brownie Sundae Recipe

Step 1: Prepare the Brownie Batter
In a large mixing bowl, cream together 1 cup of softened butter, 1 cup of brown sugar, and 1 cup of granulated sugar until light and fluffy. This step is crucial for achieving that perfect brownie texture. Add in 2 large eggs and 1 tablespoon of vanilla extract, mixing well until combined.
Step 2: Combine Dry Ingredients
In a separate bowl, whisk together 3 cups of all-purpose flour, 2 teaspoons of cornstarch, 3/4 teaspoon of kosher salt, and 1 teaspoon of baking soda. Gradually incorporate the dry ingredients into the wet mixture, stirring until just combined. Fold in 2 cups of chocolate chips, ensuring an even distribution throughout the batter.
Step 3: Bake the Brownies
Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking pan and pour the brownie batter into the pan, spreading it evenly. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs but not wet batter. Allow the brownies to cool completely in the pan.
Step 4: Prepare the Brownie Base
In a new bowl, melt 1 cup of butter. Add 1 cup of cocoa powder, 1/4 teaspoon of espresso powder, and 1/2 teaspoon of kosher salt. Mix until creamy, then stir in 1 cup of brown sugar and 1 cup of granulated sugar. Add 4 large eggs and 2 teaspoons of vanilla extract, mixing until smooth. Finally, fold in 1 cup of all-purpose flour and 1 cup of chocolate chunks, along with optional chopped pecans.
Step 5: Bake the Brownie Base
Pour the brownie base batter over the cooled brownie layer in the pan. Bake again at 350°F (175°C) for 30-35 minutes. Let it cool before cutting into squares.
Step 6: Assemble the Sundae
To create the sundae, place a generous piece of the brownie in a bowl. Top with a scoop of chocolate ice cream. In a small saucepan, melt 3 tablespoons of butter and whisk in 1/4 cup of sugar, 2 tablespoons of flour, and 1/3 cup of cocoa powder. Gradually add in 2 cups of whole milk, stirring until the mixture thickens. Pour this chocolate sauce over the brownie and ice cream for a heavenly finish.
Spring–Summer–Fall–Winter Ideas

- Spring: Add fresh berries as a topping for a burst of freshness.
- Summer: Serve with a drizzle of homemade strawberry sauce.
- Fall: Top with spiced pumpkin ice cream for a seasonal twist.
- Winter: Add a sprinkle of crushed peppermint candies for a festive touch.
Watch Outs & How to Fix
- Brownies are too dry? Make sure to not overbake. Check them a few minutes early.
- Brownies are too gooey? They may need more time in the oven; check doneness with a toothpick.
- Ice cream is melting too fast? Serve immediately after assembling the sundae.
- Not enough chocolate flavor? Consider adding more cocoa powder or chocolate chunks next time.
Keep It Fresh: Storage Guide
Store any leftover brownies in an airtight container at room temperature for up to 3 days. If you’d like to keep them longer, wrap them tightly in plastic wrap and freeze for up to a month. For the ice cream, keep it in the freezer in its original container or a well-sealed container to maintain its texture.
Ask the Chef
Can I use different types of chocolate chips?
Absolutely! Feel free to mix and match different types of chocolate chips or use chopped chocolate bars for a more gourmet touch.
What can I substitute for eggs in this recipe?
If you’d like to make this recipe egg-free, you can use flax eggs or applesauce as a substitute. Use 1/4 cup of applesauce or 1 tablespoon of flaxseed meal mixed with 2.5 tablespoons of water for each egg.
Can I make these brownies ahead of time?
Yes! The brownies can be made a day in advance. Just store them tightly wrapped, and they will stay fresh until you’re ready to serve.
What’s the best way to serve these sundaes?
These sundaes are best served immediately after assembly. However, you can prepare the brownies ahead of time and keep the components separate until serving to prevent sogginess.
