In a small bowl, mix ¼ cup sugar with 1 teaspoon cinnamon until well combined. This blend will coat your taco shells, adding that essential sweetness and fragrant spice. Set this bowl aside as we move on to the tortillas.

Take a small portion of the butter-flavored cooking spray and lightly coat the inside of a muffin tin. Each tortilla will form a unique shell in these molds, so make sure to spray them evenly. Grab a tortilla and fit it into a muffin cup, gently pressing it down to create the shell shape.

Preheat your oven to 350°F (175°C). Once ready, place the muffin tin with the tortillas into the oven. Allow them to bake for around 8-10 minutes, keeping a close eye. You'll want them to turn golden and crispy but not burned. The smell wafting through the kitchen will be enchanting.

After taking the shells out of the oven, let them cool slightly, so you don’t burn your fingers. Using a pastry brush, generously coat the warm taco shells with vanilla extract. The aroma will be irresistible! Then gently roll each shell in your cinnamon-sugar blend to achieve that lovely coating.

Now, the best part—fill these taco shells with whatever your heart desires! Ice cream, fresh fruit, or whipped cream will all work wonders. Don’t be shy; let your imagination run wild.
