You can use this simple parchment paper hack to make your own liners. Tulip shape style liners.
1. For a muffin pan, cut out 6-inch x 6-inch squares to use as liners. For a cupcake pan, cut out 5-inch x 5-inch squares. Pans vary in size and depth, so your square might be a little larger or smaller.
2. Find a drinking glass or food can that will fit in the bottom of one of the wells of the muffin or cupcake pan. I used a drinking glass for the muffin and a cocktail glass for the cupcake pan.
3. Place one square over the muffin or cupcake well. Center it in the middle of the well. Use the bottom of the drinking glass to press the parchment paper all the way to the bottom. Adjust the parchment paper if you need to, so that it’s even on all sides and press down to the bottom again.
4. Grab the glass and parchment paper with both hands (see picture below). Mold and fine tune the parchment paper over the bottom of the glass. Pressing the folded or pleated areas so that it will keep its shape.
5. To keep the liners from popping up, use some cold butter in the bottom of each muffin or cupcake well and press the parchment paper liner into place.
