Key Ingredients

- Vanilla extract- this is used in the chocolate brownie and fudge sauce recipe. Choose a quality vanilla extract for this recipe. If you can't find any, vanilla essence will work as well.
- Cake flour - Use cake flour or all-purpose flour to make this recipe.
- Milk and dark chocolate - I used a combination of milk and dark chocolate slabs; do the same or use semi-sweet chocolate chips. The chocolate flavor in this recipe depends on the quality of the chocolate you choose, so pick a great-tasting chocolate you love eating. This recipe doesn't use cocoa powder, so picking the right chocolate is important.
- Walnuts - Chocolate and nuts belong together! I have chosen to add walnuts to the brownies, but you can use pecans.
- Heavy cream - Used to make the fudge sauce; choose a high-fat heavy cream, also called heavy whipping cream.

How to Make a Hot Fudge Brownie Sundae
Preheat the oven to 170°C (340°F) and brush a 22cm (9-inch) loose-bottom tart tin with melted butter.

- Step 1: Add the chopped chocolate to a heat-proof bowl set over a saucepan of simmering water. Melt gently and stir occasionally. Set aside to cool slightly. To the bowl of an electric mixer fitted with a paddle attachment, add the sugar and butter. Beat at medium speed until the mixture is light in color and creamy.

- Step 2: Add the eggs to the butter and sugar mixture, one at a time, and beat well between additions. Scrape down the sides of the bowl and briefly mix again.

- Step 3: Sift the flour and salt together in a separate bowl. Add the dry ingredients to the egg mixture, beating at a low speed until just combined. With the mixer running at medium-low speed, add the milk and vanilla to the filling mixture and beat until just combined. Scrape down the sides of the bowl and beat again briefly.

- Step 4: With the mixer running at medium-low speed, add the melted chocolate in a steady stream to the pie filling. Use a spatula to scrape down the sides of the bowl and mix again to ensure the brownie mixture is well combined.

- Step 5: Add the chopped walnuts to the chocolate fudge pie filling and fold them through using a spatula.

- Step 6: Pour the brownie batter into the prepared baking tin and bake in a preheated oven for 30 minutes or until the filling is set but not overcooked. Allow the pie to cool to room temperature.
How to Make Chocolate Fudge Sauce

- Step 1: In a small saucepan set over medium heat, add the butter and chopped chocolate. Allow the mixture to melt while stirring occasionally.

- Step 2: Add the sugar and cream to the chocolate mixture and stir until the sugar has melted. Remove the sauce from the heat and stir in the salt and vanilla. Pour the sauce into a glass jug. Cut the brownie into squares or slices, top with vanilla ice cream and a generous amount of hot fudge sauce.

Expert Tips
- Check the true temperature of your oven using an oven thermometer.
- Don't overcook the brownies, as you want them to be fudgy in the middle while having a crust on the outside.
- Make sure the sugar has fully melted when making the sauce; otherwise, you will end up with a grainy chocolate sauce.
Hot Fudge Brownie Sundae FAQs
Yes! I couldn't decide whether to serve this as slices or squares, so I opted for a round pan and cut squares anyway! Both round and square pans will work.
This is because you didn't allow the sugar to melt while making the chocolate sauce. Rub a bit of the sauce between your fingertips. If you can feel the sugar granules, then it needs to continue cooking. Do not overheat the chocolate, as this can also affect the sauce's texture.
Both the sauce and the brownies can be frozen in separate airtight containers for up to three months. Defrost before consuming.
Store any leftover brownies in an airtight container in the fridge for up to 4 days. For any leftover sauce, store it separately in an airtight container for up to 4 days.
