Gather all ingredients
In the standing mixer bowl with a whisk attachment or in a mixing bowl with a mixer on low speed, stir the olive oil, maple syrup, and sugar together until just combined
Next add the greek yogurt, vanilla extract, egg replacer (follow package instructions on how to incorporate), and pumpkin puree into the standing mixer or mixing bowl and mix on low speed.
In a separate small mixing bowl, whisk the flour, salt, baking soda, cinnamon, and pumpkin spice together
Add dry ingredients to the wet ingredients bowl and whisk until fully incorporated
Line the cupcake mold with liners
Fill the liners just below the top. These muffins will slightly rise
Let the batter rest in the cupcake pan for 30 minutes if you've used the egg replacer. If you have used regular eggs, you can skip this resting time.
Preheat the oven to 350℉/177℃ as the batter rests
Bake for 30 minutes once the batter is done resting and the oven is preheated
To test for doneness, use a toothpick or fork and check to see if either comes out clean when you pierce the center
Allow the muffins to cool for a few minutes before serving. Enjoy!
