For the Ganache Topping

- 4 oz heavy whipping cream
How to Make High Altitude Brownie Shortbread Bars with Ganache
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C) to prepare for baking both layers of these bars.
Step 2: Prepare the Shortbread Layer
- In a mixing bowl, combine the flour, granulated sugar, and kosher salt.
- Add in the diced cold butter and vanilla extract.
- Use a fork or pastry cutter to mix until crumbly but well combined.
- Press this mixture evenly into the bottom of your greased baking pan.
- Bake for about 15 minutes until just set. Remove from oven.
Step 3: Make the Brownie Batter
- In another bowl, melt together the unsalted butter and semi-sweet chocolate chips over low heat or in a microwave.
- Once melted smooth, stir in granulated sugar followed by vanilla extract and eggs until combined.
- Sift in cocoa powder, flour, kosher salt, and optional espresso powder; mix until just combined.
- Pour this brownie batter over the pre-baked shortbread layer.
Step 4: Bake Again
Bake the layered bars for an additional 25-30 minutes until brownies are set but still fudgy in the center.
Step 5: Prepare the Ganache
While brownies cool slightly:
1. Heat heavy whipping cream in a saucepan until just simmering.
2. Pour over chopped dark chocolate in a bowl; let sit for a couple of minutes before stirring until smooth.

How to Perfect High Altitude Brownie Shortbread Bars with Ganache
Creating the perfect High Altitude Brownie Shortbread Bars with Ganache takes some attention to detail. Here are some tips to ensure your bars turn out fantastic every time.
Measure Ingredients Accurately: Use the spoon-and-level method for flour and sugar to prevent dense bars. Accurate measurements are crucial at high altitudes.
Choose Quality Chocolate: Using good-quality chocolate for both the brownie and ganache will enhance the flavor significantly. Look for chocolate with 55-60% cacao content.
Monitor Baking Time: High altitude can affect baking times. Keep an eye on your bars in the oven, checking for doneness about 5 minutes earlier than suggested.
Allow Cooling Time: Let your brownies cool completely before slicing. This helps them set properly and makes cutting easier without crumbling.
Use Instant Espresso Powder: Adding espresso powder intensifies chocolate flavor without making them taste like coffee. It’s an optional but recommended enhancement.
Best Side Dishes for High Altitude Brownie Shortbread Bars with Ganache
Pairing side dishes with your High Altitude Brownie Shortbread Bars can enhance your dessert experience. Here are some delightful options:
Fresh Fruit Salad: A mix of seasonal fruits provides a light, refreshing counterbalance to rich brownies.
Vanilla Ice Cream: The creamy texture and sweet flavor of vanilla ice cream complement chocolate desserts beautifully.
Chocolate Mousse: A light and airy chocolate mousse can add an elegant touch when served alongside brownie shortbread bars.
Nutty Trail Mix: A handful of nutty trail mix adds crunch and a hint of saltiness that contrasts nicely with sweet desserts.
Cheese Platter: Include soft cheeses like brie or goat cheese, which pair well with chocolate desserts for a sophisticated touch.
Coffee or Tea: A warm cup of coffee or tea can enhance the overall dessert experience by balancing sweetness with its warmth and aroma.
Common Mistakes to Avoid
When making High Altitude Brownie Shortbread Bars with Ganache, avoiding common pitfalls can enhance your baking experience.
- Bold Ingredients: Not measuring ingredients accurately can lead to inconsistent results. Use a kitchen scale or proper measuring cups for best outcomes.
- Bold Oven Temperature: Baking at the wrong temperature can affect texture. Always preheat your oven and consider using an oven thermometer for precision.
- Bold Overmixing Batter: Overmixing the batter can create tough bars. Mix just until combined for a fudgy texture.

- Bold Ignoring Altitude Adjustments: High altitude affects baking time and ingredient ratios. Research local adjustments specific to your area for optimal results.
