Easy Tres Leches Cake Recipe for Your Mexican Fiesta

There’s nothing worse than getting into a dinner rut, but once the school routine kicks in, it tends to happen. The same four or five meals end up in a rotation that can soon have the whole family feeling less than thrilled about sitting down to supper. So when Old El Paso Canada sent me a fabulous assortment of Dinner Kits and kitchen gadgets to help me break out of the dinner rut, I couldn’t wait to embrace the challenge.

As it happened, September 16 was El Grito de Dolores, or Mexican Independence Day, the biggest holiday on the Mexican calendar. What better way to break out of the dinner rut than to celebrate the holiday with a Mexican feast? I decided to serve up scrumptious Old El Paso hard and soft tacos complete with homemade guacamole and all the fixings. My foolproof guacamole recipe, which simply combines one mashed avocado, a few tablespoons of salsa, a spritz of lime juice and a bit of chopped fresh parsley, lets me enjoy my favourite Mexican topping in a flash!

The boys and I had a great time feasting on tacos together, but of course it’s not really a party without a special dessert! I wanted something fun and fitting with our Mexican theme, but it was still a weekday so I also wanted something quick and easy. Fortunately, my recipe for Tres Leches Cake fulfilled both requirements!

I toasted the coconut and pecans myself under the broiler; an easy job that takes less than a minute. But it does require careful monitoring as nuts burn quickly! Since my boys were going to be eating the cake too, I used rum extract instead of actual rum, but for an adult gathering, using rum turns the cake into a delicious and unique dessert. And it was the perfect finish to our El Grito celebration!
