What you will need? 

For the Brownie Loaf

• 1½ cups all-purpose flour (180 g)
  Purpose: Provides structure for a fudgy yet tender loaf.
  Substitution: Use a 1:1 gluten-free flour blend or whole wheat flour (may make loaf denser), as you’ve explored gluten-free options in recipes like the Sourdough Bacon Cheddar Scones.
• ½ cup cocoa powder (45 g)
  Purpose: Adds rich chocolate flavor and color.
  Substitution: Use Dutch-processed cocoa for a smoother taste or carob powder for a caffeine-free option (flavor will differ slightly), as seen in your Sourdough Chocolate Zucchini Muffins.
• 1 tsp baking soda
  Purpose: Helps the loaf rise and stay soft.
  Substitution: Use 2 tsp baking powder if out of soda (texture may be slightly less fudgy).
• ½ tsp salt
  Purpose: Balances sweetness and enhances chocolate flavor.
  Substitution: Use sea salt or reduce to ¼ tsp for low-sodium diets, aligning with your customizable seasoning preferences.
• ½ cup salted butter (for loaf, 115 g)
  Purpose: Browned to add nutty, rich flavor and moisture.
  Substitution: Use unsalted butter (add ¼ tsp salt), vegan butter, or coconut oil for dairy-free (loses some browning flavor), as you’ve used various fats in recipes like the Lemon Zucchini Muffins.
• ¾ cup granulated sugar (150 g)
  Purpose: Sweetens and tenderizes the loaf.
  Substitution: Use brown sugar for a deeper molasses flavor, coconut sugar, or a 1:1 sugar substitute like erythritol (check package for baking ratios), as seen in your Sourdough Oatmeal Breakfast Cups.
• 2 eggs, at room temperature
  Purpose: Binds and adds structure for a fudgy texture.
  Substitution: Use 2 flax eggs (2 tbsp ground flaxseed + 6 tbsp water, let sit 5 minutes) for vegan, aligning with your vegan swaps in recipes like the Sourdough Oatmeal Breakfast Cups.
• 1 tsp vanilla extract (for loaf)
  Purpose: Enhances sweetness and rounds out flavors.
  Substitution: Use ½ tsp almond extract or a vanilla bean (scraped) for a gourmet touch, similar to your preference for bold flavors in baked goods.
• 1 cup buttermilk, at room temperature (240 ml)
  Purpose: Adds tang and keeps the loaf moist.
  Substitution: Use 1 cup milk (dairy or plant-based) + 1 tbsp lemon juice (let sit 5 minutes), Greek yogurt thinned with water, or vegan buttermilk, as you’ve liked tangy ingredients in recipes like the Easy Greek Chicken Meatballs.
• ½ cup hot fudge sauce (120 g)
  Purpose: Adds gooey, intense chocolate flavor to the loaf.
  Substitution: Use melted chocolate mixed with 2 tbsp cream or a store-bought chocolate syrup, though homemade hot fudge (below) is richest.
• ½ cup chocolate chips (85 g)
  Purpose: Adds melty, sweet bursts of chocolate.
  Substitution: Use dark, milk, or white chocolate chips, chopped chocolate bars, or nuts for texture, as you’ve liked mix-ins in the Sourdough Chocolate Zucchini Muffins.

For the Hot Fudge Sauce

• ¼ cup salted butter (55 g)
  Purpose: Adds richness and smooth texture to the sauce.
  Substitution: Use unsalted butter (add a pinch of salt) or vegan butter for dairy-free.
• ⅔ cup semi-sweet chocolate chips (115 g)
  Purpose: Provides deep chocolate flavor and thickens the sauce.
  Substitution: Use dark or milk chocolate chips or chopped chocolate bars.
• 8 oz evaporated milk or half and half (240 ml)
  Purpose: Creates a creamy, pourable consistency.
  Substitution: Use heavy cream, whole milk, or plant-based milk (e.g., oat or coconut) for dairy-free, though sauce may be thinner.
• ¾ cup granulated sugar (150 g)
  Purpose: Sweetens and thickens the sauce.
  Substitution: Use brown sugar or a 1:1 sugar substitute (adjust for taste), as you’ve used in baked goods.
• 6 tbsp cocoa powder (30 g)
  Purpose: Intensifies chocolate flavor in the sauce.
  Substitution: Use Dutch-processed cocoa or carob powder, as above.
• ¼ tsp salt
  Purpose: Enhances chocolate and balances sweetness.
  Substitution: Use sea salt or omit for low-sodium diets.
• 2 tbsp vanilla extract
  Purpose: Adds depth and rounds out the sauce’s flavor.
  Substitution: Use 1 tbsp for a milder flavor or 1 tsp almond extract for a twist.

Step-By-Step Guiding

Follow these detailed steps to create a gooey brown butter hot fudge brownie loaf

1️⃣ Preheat and Brown Butter

• Preheat your oven to 350°F (175°C). Grease a 9×5-inch loaf pan or line with parchment paper for easy removal.
• In a medium saucepan over medium heat, melt ½ cup salted butter. Continue cooking, swirling occasionally, until it turns golden brown and smells nutty (about 5–7 minutes). Remove from heat and let cool slightly.
• Tip: Watch the butter closely to avoid burning; it should have brown flecks and a caramel-like aroma, as you’ve liked precise techniques in recipes like the Sourdough Chocolate Zucchini Muffins.

2️⃣ Mix Dry Ingredients

• In a large bowl, whisk together 1½ cups all-purpose flour, ½ cup cocoa powder, 1 tsp baking soda, and ½ tsp salt until well combined.
• Tip: Sift cocoa powder if lumpy to ensure a smooth batter, a method you’ve appreciated in chocolate recipes. Whisk thoroughly to distribute leavening agents.

3️⃣ Mix Wet Ingredients

• In another bowl, combine the cooled browned butter, ¾ cup granulated sugar, 2 eggs, 1 tsp vanilla extract, and 1 cup buttermilk. Whisk until smooth and fully blended.
• Tip: Ensure eggs and buttermilk are at room temperature to prevent curdling with the butter, as you’ve preferred in baked goods like the Lemon Zucchini Muffins.

4️⃣ Combine and Fold

• Pour the wet ingredients into the dry ingredients and stir gently with a spatula until just combined. Fold in ½ cup hot fudge sauce and ½ cup chocolate chips until evenly distributed.
• Tip: Avoid overmixing to keep the loaf fudgy, a technique you’ve liked in recipes like the Sourdough Chocolate Zucchini Muffins. The batter will be thick but pourable.

5️⃣ Bake and Cool

• Pour the batter into the prepared loaf pan and smooth the top. Bake for 45–50 minutes, or until a toothpick inserted in the center comes out with a few moist crumbs (not wet batter).
• Let cool in the pan for 10 minutes, then transfer to a wire rack to cool further.
• Tip: Check doneness at 45 minutes to avoid overbaking, as you’ve preferred gooey textures in desserts. Use parchment overhangs to lift the loaf out easily.

6️⃣ Make Hot Fudge Sauce

• In a medium saucepan over medium heat, melt ¼ cup salted butter and ⅔ cup semi-sweet chocolate chips, stirring until smooth.
• Add 8 oz evaporated milk, ¾ cup granulated sugar, 6 tbsp cocoa powder, and ¼ tsp salt. Stir continuously until thickened, about 5 minutes.
• Remove from heat and stir in 2 tbsp vanilla extract. Let cool slightly before serving (sauce will thicken as it cools).
• Tip: Stir constantly to prevent scorching, and adjust thickness with a splash of milk if needed, as you’ve liked smooth sauces in recipes like the Coconut Chocolate Cupcakes.

7️⃣ Serve

• Slice the brownie loaf into 8 pieces. Top each slice with a scoop of vanilla ice cream and a generous drizzle of warm hot fudge sauce. Serve immediately for maximum gooeyness.
• Tip: Warm the loaf slices slightly in the microwave (10–15 seconds) before topping for an extra indulgent texture, a presentation style you’ve enjoyed in decadent desserts.

Topping Suggestions

• Whipped Cream: A fluffy addition alongside ice cream.
• Chopped Nuts: Hazelnuts or pecans for crunch.
• Sea Salt Flakes: A pinch to enhance chocolate flavor.
• Fresh Berries: Raspberries or strawberries for a tart contrast.
• Caramel Drizzle: For extra sweetness and decadence.
• Sprinkles: Fun and colorful for kids or parties.

How to Store & Reheat

• Storage:
  • Store the brownie loaf in an airtight container at room temperature for up to 2 days or in the refrigerator for up to 5 days. Store hot fudge sauce separately in the fridge for up to 1 week.
  • Tip: Wrap the loaf tightly in plastic wrap to keep it fudgy. Reheat sauce gently before serving, as you’ve liked maintaining texture in desserts.
• Freezing:
  • Freeze the loaf (without sauce or ice cream) in a freezer-safe container or wrapped tightly in plastic and foil for up to 3 months. Freeze hot fudge sauce in an airtight container for up to 2 months.
  • Thaw the loaf at room temperature for 2–3 hours or overnight in the fridge. Thaw sauce in the fridge and reheat gently.
  • Tip: Slice the loaf before freezing for easy portioning, a practice you’ve appreciated in recipes like the Sourdough Oatmeal Breakfast Cups.
• Reheating:
  • Loaf: Microwave slices for 10–15 seconds for a warm, gooey texture, or reheat in a 300°F (150°C) oven for 5–7 minutes, wrapped in foil.
  • Hot Fudge Sauce: Reheat in a saucepan over low heat, stirring, or microwave in 15-second intervals, stirring until smooth. Add a splash of milk if too thick.
  • Tip: Refresh with fresh ice cream and sauce after reheating, as you’ve liked revitalizing desserts in recipes like the Coconut Chocolate Cupcakes.
