Preheat oven to 350 degrees F. Line 6 jumbo muffin pan cups with paper liners.
In a large bowl, combine flour, sugar, cocoa, baking powder, baking soda, and salt and whisk to blend.
In a medium bowl, combine buttermilk, eggs, and butter. Add the flour mixture and stir to combine.
Spoon the batter into the muffin cups and fill 3/4 full.
Make the streusel in a small bowl. Mix the flour and sugar. Add the butter and mix with a fork until crumbly. Spoon about 1 T. of the streusel over each muffin.
Bake the muffins until set, about 30-35 minutes for jumbo muffin cups. Let cool for 5 minutes.
Prepare strawberry "carrots". Melt candy melts in 30 second increments. Once melted dip strawberries to cover all the way up to the stem. Place on parchment to let harden.
Once muffins have cooled, add your strawberry "carrot" to the center of the muffin and enjoy!
