Nutella Buttercream

• 1 cup salted butter at room temperature: Provides the creamy base for the buttercream and adds a rich, buttery flavor.
• 3/4 cup Nutella: Adds a nutty, chocolatey flavor to the buttercream.
• 1 tbsp Frangelico or 1/2 tsp pure vanilla extract: Enhances the overall flavor of the buttercream.
• 3-4 cups powdered sugar: Sweetens the buttercream and gives it structure.
• 1/4 cup cocoa powder: Adds a rich chocolate flavor to the buttercream.
• 6-8 tbsp heavy whipping cream: Thins the buttercream to the desired consistency and adds a creamy texture.

Step by Step Instructions

Nutella Brownies

1. Preheat Oven: Preheat the oven to 350°F (175°C) and line & spray an 8×8 baking pan with parchment paper, leaving an overhang to easily remove brownies after baked.
2. Melt Chocolates and Butter: In a large microwave-safe bowl, combine the milk chocolate chips, dark/unsweetened Belgian chocolate, and butter. Heat on 50% power or the defrost setting for 1 minute, then remove and stir. Continue heating in 15-30-second intervals until the mixture is completely melted & smooth. Be careful not to overheat.
3. Add Nutella: Stir the Nutella into the melted chocolate mixture.
4. Mix Eggs and Sugar: Using a stand mixer with the paddle attachment, or electric mixer, mix the eggs, egg yolk, and sugar on medium-high speed until fully combined & mixture has lightened in color – about 3-5 minutes.
5. Add Vanilla: Add the vanilla extract and beat for 30 seconds more.
6. Combine Mixtures: Remove from mixer, and stir in the cooled chocolate mixture with a rubber spatula. Next, gently fold in the flour and cocoa powder.
7. Bake: Pour the brownie batter into the prepared baking pan and bake for 35-40 minutes. You want to bake until a toothpick or tester comes out with moist crumbs still attached. Let cool to room temperature before adding icing.

Nutella Buttercream

1. Cream Butter and Nutella: Mix butter on medium-high speed using the paddle attachment on a stand mixer until light and fluffy.
2. Add Flavorings: Add the Nutella, Frangelico (or vanilla), and mix for 1 minute more.
3. Add Sugar and Cocoa: Add the powdered sugar (starting with 4.5 cups), the cocoa powder, and 6 tbsp of whipping cream, and mix on low to combine.
4. Incorporate Ingredients: Scrape down the sides and bottom of the bowl using a silicone spatula and mix on medium until frosting is smooth and creamy. Adjust to desired consistency by adding whipping cream to thin it out or powdered sugar to thicken it.

Assembly

1. Prepare Pastry Bag: Transfer Nutella buttercream to a pastry bag fitted with a star tip.
2. Pipe Buttercream: Once the brownies have fully cooled, pipe the buttercream onto the top of your brownies by holding your piping bag at a 90-degree angle over the brownies. Squeeze a small burst of pressure, release, and quickly pull upwards. Repeat until brownies are fully covered. Or ice using a spatula.
3. If using Valentine’s Day Cookie Cutters, cut brownies into desired shapes and add sprinkles.
4. Drizzle with additional Nutella. To make drizzling easier, you can warm it slightly in the microwave for 10 seconds or so.

Tips for the best Fudgy Nutella brownies

• Quality Matters: Use high-quality Belgian chocolate and Dutch-processed cocoa for the richest flavor.
• Pro Tip: Add 1 teaspoon of espresso powder to enhance the chocolate flavor without adding coffee taste.
• Don’t Overbake For Extra Gooey Brownies: If you like your brownies extra gooey, slightly underbake them. Keep an eye on the baking time and test with a toothpick. It should come out with a few moist crumbs, not completely clean.
• Use Room Temperature Ingredients: Make sure all your ingredients (especially eggs and butter) are at room temperature before you start. This helps ensure that everything mixes together smoothly and evenly.
• Don’t Overmix the Batter: After adding the flour and cocoa powder, mix the batter until just combined. Overmixing can lead to tough brownies.
• Line the Pan: Lining your baking pan with parchment paper makes it easy to lift the brownies out once they’re done. This helps prevent sticking and makes cutting them into squares a breeze.
• Let Brownies Cool Completely: Allow the brownies to cool completely in the pan before icing and cutting. This helps them set properly and makes them easier to cut into shapes or neat squares.
• Add Mix-Ins: Feel free to add mix-ins like chocolate chips, chopped nuts, or even a swirl of caramel or extra Nutella for added texture and flavor.
• Store Properly: Store your brownies in an airtight container at room temperature for up to 4 days or refrigerate for up to a week. You can also freeze them for longer storage.

I hope you enjoy these delicious fudgy Nutella brownies as much as I do. Happy baking, friends! These brownies are perfect for Valentine’s Day, or any time you want to share a sweet treat with loved ones.
