Step 1: Get the Filling Ready: Grab a medium bowl. Toss in your finely chopped peaches, brown sugar, ground cinnamon, and vanilla extract. Give it a good stir to combine everything. Now, pour in the 2 tablespoons of melted unsalted butter and mix again. The butter helps make the filling luscious and prevents it from being too dry. Set this bowl aside for a moment.
Step 2: Prep the Dough: If you're using crescent roll dough, don't separate the triangles! Just unroll the whole sheet and gently press the seams together to form a rectangle. If you're using puff pastry, make sure it's thawed according to package directions and unfold it or roll it out slightly into a roughly rectangular shape. You want a nice surface to spread your filling on.
Step 3: Fill 'Er Up! Take your glorious peach filling and spread it out evenly over your dough rectangle. Leave a small border around the edges – maybe about half an inch – so the filling doesn't ooze out when you roll it up. I like to use an offset spatula for this, but the back of a spoon works just as well!
Step 4: Roll and Slice: Starting from one of the shorter ends of the rectangle, roll the dough up tightly, like you're making a jelly roll. Once you have a log, use a sharp knife to slice the roll lengthwise right down the middle. You should now have two long strips with the peach filling swirl exposed on the cut side.
Step 5: Twist and Coil: This is where the magic happens! Take one of your strips. Twist the two cut sides together, trying to keep the filling showing. It's okay if it's a little messy – that's part of the charm! Once you have a twisted strip, coil it up like a snake into a circle or muffin shape. Place each coiled cruffin into a greased muffin tin cup. Repeat with the other strip.
Step 6: Bake Time! Pop your muffin tin into a preheated oven at 375°F (190°C). Let them bake for about 18–22 minutes. You'll know they're ready when they're beautifully golden brown and puffed up. They'll smell amazing!
Step 7: Butter and Sugar Shine: As soon as they come out of the oven, while they're still lovely and warm, brush the tops generously with a little extra melted unsalted butter. Immediately sprinkle the tops with the 2 tablespoons of granulated sugar. This creates a wonderful sweet crust! Let them cool in the tin for just a few minutes before trying to move them.
Step 8: Final Touch (Optional): Once they've cooled slightly, you can give them a light dusting of powdered sugar if you like! It makes them look extra special.
