1. In a medium bowl, mix the softened cream cheese and confectioners’ sugar until smooth and creamy. Set aside.
2. Take the slices of brioche or challah and spread a generous layer of the cream cheese mixture on half of the slices. Top with the other half of the slices to form sandwiches.
3. In a shallow dish, whisk together the eggs, milk, vanilla extract, 1 teaspoon of cinnamon, and 1/4 cup of granulated sugar until well combined.
4. Heat a large skillet over medium heat and add the butter, allowing it to melt and coat the pan evenly.
5. Dip each sandwich into the egg mixture, ensuring both sides are well coated, and place them in the skillet.
6. Cook each side for about 3-4 minutes or until golden brown. Adjust the heat as necessary to prevent burning.
7. While the French toast is cooking, mix 1/2 cup of granulated sugar and 1 tablespoon of cinnamon in a shallow dish.
8. Once the sandwiches are cooked, immediately dredge them in the cinnamon-sugar mixture, coating both sides thoroughly.
9. Serve warm, and enjoy the delightful combination of creamy, crunchy, and sweet in every bite.

This step-by-step guide should make the cooking process both enjoyable and rewarding. Remember, the secret ingredient is always love, so take your time and savor each moment in the kitchen.
