Why You'll Love This Recipe
- Chocolate, cocoa powder, and chocolate chips- This recipe has melted chocolate, cocoa powder, and chocolate chips. These brownies are guaranteed to be super decadent and chocolatey!
- Plenty of bourbon- There's ¼ cup of bourbon whiskey in these brownies, so they definitely have a kick to them and some warmth. Bourbon and chocolate is match made in heaven!
- Quick and easy- You can whip up a batch of brownies in under an hour with a handful of simple ingredients!
Here are notes about some of the ingredients used. For quantities and full instructions, see the recipe card below.
- Chocolate- I prefer bittersweet or dark chocolate so the brownies aren't overwhelmingly sweet. Look for chocolate with 70% cacao or more. Use chocolate bars instead of chocolate chips because they're easier to melt.
- Oil- Making brownies with oil instead of butter keeps them moist and gooey! Use any flavorless oil, like avocado, canola, or vegetable oil.
- Bourbon- Choose a bourbon that you enjoy drinking since its flavor will come through the brownies. Some people prefer a smooth, milder Kentucky bourbon, while others like the robust flavors of a more aged or spicy bourbon. Maker's Mark and Woodford Reserve are both good brands for baking.
- Sugars- This recipe uses granulated sugar and brown sugar to sweeten and add moisture. You can use light or dark brown sugar.
- Eggs- Whole eggs play a crucial role in binding the ingredients together and helping the brownies set while baking. It's important that the eggs are room temperature- pull them out of the fridge 1-2 hours before starting.
- Egg white- Including an additional egg white is key for giving the brownies a lift, especially since there's no baking powder or baking soda in the recipe! It needs to be room temperature too.
- All purpose flour- Flour is what gives brownies their structure. You need less than you might think, so use a kitchen scale for an accurate measurement.
- Cocoa powder- I typically reach for Dutch-processed cocoa powder because of its rich, chocolatey flavor and deep color, but you can also use natural (or unsweetened) cocoa powder if you prefer.
- Chocolate chips- Mix semi-sweet chocolate chips or a chopped chocolate bar into the bourbon brownie batter.
Substitutions & Variations
- If you aren't a bourbon fan, dark rum, amaretto, and Kahlua are also great for making boozy brownies. Peanut butter whiskey would be an amazing substitution too!
- Add a handful of nuts to the brownie batter. Pecans and bourbon is a natural pairing (especially with chocolate- yum), but walnuts are delicious too!
Helpful Equipment & Tools
- Bake the brownies in an 8x8" or 9x9" square baking pan. Metal pans are recommended for brownies as they heat up more evenly than glass, resulting in a better rise and crisp edges. If you use a glass pan, you'll need to cook the brownies a bit longer (about 10 extra minutes).
- I recommend whipping the eggs and sugar with an electric hand mixer to get them nice and frothy (for a crinkly top)! If you don't have one, you can whisk the eggs by hand vigorously.
Step by Step Instructions
Before you start, preheat the oven to 350°F/180°C and grab a square baking pan and line it with parchment paper. Leave about 2 inches of parchment hanging over the sides of the pan for easy brownie removal. I usually use binder clips to keep the paper in place.
STEP 1: Start by melting the chocolate in a heatproof bowl in the microwave for about 2 minutes, mixing every 15 seconds or so until it's completely melted.
STEP 2: Next, whisk the oil, bourbon, and vanilla into the melted chocolate and let it cool slightly. The alcohol might make the chocolate solidify a bit like in the photo above, but that's ok! If it gets too solid, microwave for 10-30 seconds.
STEP 3: In a large mixing bowl, beat together granulated sugar, brown sugar, eggs, and egg white on medium-high speed for 2-4 minutes with a handheld mixer until the frothy and pale.
STEP 4: As you whisk the eggs and sugar, gradually pour in the melted chocolate mixture. Keep beating until thoroughly combined.
STEP 5: Next, fold the all purpose flour, cocoa powder, and salt into the wet ingredients with a rubber spatula or with the mixer on low speed. Mix until the dry streaks of flour mostly disappear, then mix in the chocolate chips.
STEP 6: Pour the brownie batter into the prepared baking pan, spreading it evenly across the pan. Bake for 26-32 minutes or until a toothpick inserted in the center comes out with moist crumbs attached.
STEP 7: Remove the bourbon brownies from the oven and let them cool in the pan for 10 minutes. Transfer them to a wire cooling rack and cool to room temperature. Then you can slice and serve them!
Expert Baking Tips
- Measure the flour accurately. Flour is easy to over-measure, and brownies require less than you'd think! I recommend weighing it in grams, but you can also use the spoon and sweep method.
- Don't overmix the batter. Overmixing makes brownies cakey instead of fudgy. Mix until there is just a few dry patches of dry ingredients, then fold in the chocolate chips until the dry streaks just disappear.
- Don't overbake the brownies. There's nothing worse than dry brownies! They're done when a toothpick inserted in the center comes out with moist crumbs but not wet batter. The center will be a bit jiggly. They'll firm up as they cool.
Storage & Freezing
Store leftover bourbon brownies in an airtight container at room temperature for up to 5 days. When you're ready to enjoy them again, simply reheat in the microwave for 10 seconds for a warm, freshly baked feel or eat them as is.
Cut the brownies into slices and put sheets of parchment or wax paper between each slice to prevent them from sticking together. Transfer them to an airtight container and freeze for up to 3 months. Let the brownies thaw on the counter for 3-4 hours before serving.
Frequently Asked Questions
I made these brownies with and without the bourbon while testing, and I don't recommend leaving it out. Without it, the brownies are a bit cakey and dry. If you don't consume alcohol or don't like bourbon, try these olive oil brownies or almond brownies instead!
Overbaking, too much flour, overmixing the batter, and incorrect oven temperature can cause dry brownies. Measure the flour accurately, avoid overmixing, and use an oven thermometer to check the temperature to prevent dryness.
Most of the alcohol is burned off during baking, so eating them is very unlikely to make you drunk!
