Preheat the oven to 350 degrees. Line a muffin tin with cupcake liners.
In a large bowl cream the butter, sugar, and brown sugar.
Add in the eggs and mix well.
Stir in the orange zest, vanilla, and almond. Set aside.
In a medium bowl combine the flour, baking powder, and salt.
Add the dry ingredients to the wet ingredients and mix well.
Add the almond milk and orange juice and stir until combined.
Fold in the grapes.
FIll each muffin cup with the cake batter. Sprinkle the tops with clear sanding sugar if desired.
Bake for 25-30 minutes or until a toothpick inserted into the center comes out clean.
Before removing from oven, broil the tops for 1-2 minutes to get a nice golden brown top.
Remove from oven and cool for at least 20 minutes before serving.
