Preheat oven to 350°F (175°C). Line one or more baking sheets with parchment paper.
In a large bowl, cream together 1 cup softened butter, 1 cup sugar, and 2 tablespoons strawberry Jell‑O until light and fluffy. Add 2 eggs and 1 teaspoon vanilla extract; mix until combined.
In a separate bowl, whisk together 2 1/2 cups all‑purpose flour, 3.5 ounces white chocolate instant pudding mix, 1 teaspoon baking soda, and 1/2 teaspoon salt.
Gradually add the dry ingredients to the butter mixture and mix until just combined.
Stir in 1 cup white chocolate chips.
Drop rounded tablespoons of dough onto the prepared baking sheet, spacing about 2 inches apart.
Bake in the preheated oven for 9–11 minutes, until the edges are set and the tops are lightly set.
Remove cookies from the oven and let them cool completely on the parchment paper.
While the cookies cool, place 24 ounces almond bark in a medium pot over LOW heat and stir constantly until fully melted and smooth. Remove from heat.
Dip each cooled cookie halfway into the melted almond bark, allow excess to drip off, then place back on the parchment-lined baking sheet.
Immediately add sprinkles to the wet almond bark coating. Let the cookies sit at room temperature until the almond bark is fully set.
