Preheat the oven to 350°F/177°C.
Prepare muffin tins by coating with non-stick cooking spray (can use parchment liners or silicone cups as well). Set aside.
In a mixing bowl, use mixer to beat yogurt, mango, and lemon zest until well mixed.
Add coconut oil, vanilla extract, and egg and beat on low speed until well incorporated.
Add almond flour, baking powder, and salt. Mix until the flour is incorporated.
Add red currents and fold into batter with rubber spatula.
Evenly scoop batter into prepared cups. Bake until a toothpick inserted into the center of a muffin comes out clean, about 20 minutes.
Remove from the oven and allow muffins to cool in muffin tin for 15 minutes. Turn muffins out onto wire cooling rack to finish cooling. Decorate with a few red currants (optional) and serve.
