Preheat oven and prepare pan:

Heat oven to 350°F (175°C). Insert paper liners into a 12-cup muffin pan.

Mix batter ingredients:

In a bowl, whisk together flour and baking powder. Add sugar, vanilla paste, softened butter, eggs, and milk. Mix on low speed with an electric mixer until combined, then beat on high for 2 minutes until batter is smooth.

Fill liners and bake:

Using two spoons, distribute batter evenly among the liners. Position pan on oven rack and bake approximately 30 minutes, until a toothpick inserted in the center comes out clean.

Cool muffins in pan:

Allow muffins to rest in pan for 10 minutes, then transfer to a wire rack to cool fully.

Liquefy glaze in hot water:

For decoration: Boil water in a small saucepan, then remove from heat. Submerge the closed glaze container in the hot water for about 10 minutes to liquefy.

Cut gum triangles and remove wafer:

Meanwhile, snip green fruit gum strips into triangles with scissors. With a small sharp knife, remove the wafer base from each marshmallow kiss.

Glaze muffins and decorate:

Working one at a time, brush melted glaze evenly over each muffin (glaze sets fast). Immediately place a marshmallow kiss in the center as the head. Dust with green sugar sprinkles. Use the white icing pen to affix sugar eyes. Lastly, attach the green fruit gum triangles as spikes along the dinosaur's back.
