For cake mix: Whisk together a box of your favorite flavor of cake mix with 1 cup of water or milk, 1/3 cup safflower oil, and 3 eggs. Heat up a waffle iron and spritz with cooking spray. Ladle in a spoonful or two of the batter and cook until the waffle is crisp. Stash the waffle in a 300 degree oven to stay warm while you make more.
For brownie mix: Dump the brownie mix (ghirardelli 20 ounce dark chocolate is recommended) into a large mixing bowl along with 1/2 teaspoon kosher salt. Crack 3 eggs into the bowl, then pour in 1/3 cup grapeseed or canola oil and 5 tablespoons melted butter. Mix until well combined, then add a big splash of very fizzy seltzer.
At this point, you can heat the waffle iron and get down to business. Alternatively, you can jazz up the brownie waffle batter with some mix-ins. Classic brownie lovers may want to go with finely chopped walnuts, while chocoholics may opt for chopped chocolate. Peanut butter, butterscotch, and white chocolate chips also won’t disappoint. Whatever you choose, fold in about 1/2 cup of the mix-in into the batter.
Heat your waffle iron and grease it with cooking spray or melted butter. Cook waffles in whatever manner the waffle iron’s directions recommend.
Another (simpler) variation: eggs, water and oil as directed on the box
1 additional egg
1 box Ghirardelli Triple Chocolate brownie mix
Whisk together eggs, water, and oil until combined. Add brownie mix and mix until just combined.
Pour into preheated waffle maker and bake for 3 minutes or as directed on your waffle maker.
Remove and enjoy topped with fruit, whipped cream, hot fudge, caramel sauce, or ice cream.
1 box (1 lb 3.8 oz) Betty Crocker Supreme walnut brownie mix
1/4 cup vegetable oil
Heat waffle maker. (Waffle makers without a nonstick coating may need to be brushed with vegetable oil or sprayed with cooking spray before batter for each waffle is added.) In large bowl, stir brownie mix, eggs and oil with whisk just until smooth.
Pour slightly less than 3/4 cup batter onto center of hot waffle maker. (Check manufacturer’s directions for recommended amount of batter.) Close lid of waffle maker. Bake about 5 minutes or until steaming stops. Carefully remove waffle. Repeat with remaining batter.
