Preheat the oven to 350℉ and line the muffin tins with the liners.
In a large bowl, combine 2 cups all purpose einkorn flour, 1 tbsp baking powder, ¼ tsp baking soda and ¼ tsp pink Himalayan salt with a whisk.
Add in 1 large egg, ⅓ cup organic butter (melted), 3 tbsp organic maple syrup, ½ cup organic whole milk, ¼ cup Whole fat Greek yogurt and 2 tsp vanilla extract.
Use a wooden spoon to mix together- about 2 minutes. With einkorn flour you don't want to over mix. Add in the ½ cup organic blueberries and mix again.
Set aside and in a small pan over low/medium heat combine 1 cup organic blueberries and ½ cup organic maple syrup. Let simmer over medium low stirring frequently about 15 minutes until the sauce turns into a glaze.
Scoop 1 small cookie scoop or 1 tbsp. of the dough into each muffin tin.
Scoop ½ tsp.-1 tsp. of the blueberry mixture on top of each. Use a toothpick and swirl into the dough. Do this for each muffin.
Place another 1 small cookie scoop or 1 tbsp. dough on top.
In a medium bowl with a pastry cutter or fork combine together 4 tbsp organic butter, ½ cup all purpose einkorn flour, and ¼ cup organic turbinado sugar.
Split between the 12 muffins. About 1 tbsp. crumbled onto each.
Bake at 350℉ for 18-22 minutes until cooked through.
