1️⃣ In a medium bowl, whisk together the milk, eggs, sugar, vanilla, and cinnamon until well combined. 🥣

2️⃣ Grease a 12-cup muffin tin. Add about 1 cup of bread cubes to each muffin cup. 🧈

3️⃣ Carefully pour the egg and milk mixture evenly over the bread in each muffin cup. Press down on the bread cubes gently, then pour more mixture as needed to soak all the bread. (Alternatively, you can combine everything in a large bowl and then fill the muffin cups.) Cover the muffin tin with plastic wrap and refrigerate for at least 2 hours or up to overnight. 🕒❄️

4️⃣ When ready to bake, preheat your oven to 350°F (175°C). 🔥

5️⃣ To make the cinnamon streusel, combine cold butter, brown sugar, flour, cinnamon, and salt in a small bowl. Mix with your hands until the mixture becomes crumbly. 🍂

6️⃣ Remove the muffin tin from the refrigerator. Evenly sprinkle the streusel topping over the muffins. 🍥

7️⃣ Bake for 25 minutes or until the tops are golden brown. ⏳

8️⃣ Let the muffins cool for about 5 minutes, then remove them from the pan. Serve warm with butter and maple syrup if desired. Enjoy! 😋
