Preheat oven to 350°F/175 C. Line wells in a cupcake/muffin pan with liners.
In a medium bowl, combine the flour, baking powder, baking soda, salt, and matcha. Stir to evenly distribute everything.
In a large bowl, combine the almond milk, sugar, oil, and vinegar. Whisk until well blended and the sugar is starting to dissolve.
Add the flour mixture and almond flour and mix until just combined. Do not over mix.
Pour about ⅓ cup (78 ml) of batter into prepared wells and shake to level. Cover the batter with a single layer of sliced almonds.
Bake for 18-20 minutes until a skewer inserted comes out clean.
Allow to cool in the tin for at least 5 minutes before removing and allow to cool completely.
Notes
Dissolving the sugar: Allowing the sugar to almost fully dissolve in the wet ingredients before mixing it together with the flours makes mixing easier and contributes to soft muffins with a delicate crumb texture.
Don’t overmix: When pouring the dry ingredients into the wet, do not overmix the batter. Stir until just combined. Overmixing the batter will lead to tough muffins, as is the case with these banana pumpkin muffins, too.
Go easy on the almonds: You want to top the muffins with slivered almonds before baking. However, make sure they’re all in a single layer and not clumped in the center. This gives a better texture to the muffins.
