Wash the strawberries thoroughly and pat them dry. Set aside.
Then break the pretzel sticks in half and press the broken ends into the mini marshmallows.
Melt 1/4 cup of white chocolate in a very small bowl, then dip the ends of the pretzels into the white chocolate. Place on a parchment-lined plate and repeat with the remaining pretzels and marshmallows. Then place the pretzels in the freezer to help the white chocolate firm up.
Next, melt 2 cups of milk or dark chocolate in a large, thick, heat-proof glass. Heat it in 30-second intervals, stirring in between, until fully melted. Then mix 2 tsp of vegetable, canola, or coconut oil into the chocolate to thin it, and stir until combined. This will make it way easier to dip the strawberries!!
Dip the strawberries in the melted chocolate and let any excess run off before scraping the bottom of the strawberries on the edge of the glass and placing them on a large, parchment-lined plate. Set aside.
Remove the pretzels from the freezer. Pick them up by the white chocolate end and dip them into the melted chocolate, covering the entire marshmallow and pretzel (except the white chocolate ends). Scrape off any excess chocolate on the bottom of the leg on the edge of the glass, then gently place them on the sides of the strawberries to look like legs. The heat from your fingertips might melt the white chocolate a bit, so be sure to wipe your fingertips clean after each dip.
Once you've added two legs to each strawberry, place the plate in the fridge to help the chocolate firm up. These can sit at room temperature for up to a day, or be kept in the fridge for 2-3 days. Store them on a plate covered loosely with plastic wrap or foil. Strawberries release carbon dioxide, so they will spoil faster if stored in an airtight container.
