Why Organic
Why use organic ingredients in this recipe? You all know I’m a huge organic advocate, and I bet you may be thinking sometimes, Why would I even bother to use organic ingredients in something that is so sweet and indulgent? But, that is the exact reason why you should use organic ingredients! Sweet things need to have flavor in order to be good, otherwise they are just sweet and they don’t taste like much else. Organic ingredients are more pure than conventional ones, therefore they actually have more flavor than the non organic options. Say it with me, organic means more flavor! And not just more flavor but a more true and pure flavor. And organic ingredients are much healthier for you to eat in general as they do not contain GMOs or anything artificial. Plus, you are being environmentally friendly when you choose organic ingredients!
So, I highly recommend that you buy the best organic ingredients for this recipe! You can also shop my Amazon Storefront for all my favorite organic ingredients here.

Ingredients
- Batter
300 grams (2 1/3 cups) organic all purpose flour
2 teaspoons organic cinnamon
1 ½ teaspoons baking soda
1 teaspoon organic ground ginger
3/4 teaspoon fine sea salt
1/2 teaspoon organic ground cloves
1 cup (226 grams) organic salted butter, softened
400 grams (3 1/2 cups) packed organic light brown sugar
2 organic large egg yolks
425 grams (one 15-ounce can) organic pumpkin puree
113 grams (1/2 cup) organic sourdough discard
- Frosting
1 cup (226 grams) organic salted butter, softened
4 ounces organic cream cheese
88 grams (1/4 cup) organic maple syrup
20 ounces (4 cups) organic powdered sugar, sifted
- Topping
1 tablespoon organic cane sugar
Pinch of organic cinnamon
Organic cinnamon sticks (optional)
Directions
- Preheat the oven to 375°F. Line 2 cupcake tins with liners.
- To make the batter: In a large mixing bowl, add the flour, cinnamon, baking soda, ginger, sea salt, and cloves. Whisk together to combine completely and set aside.
- In the bowl of a stand mixer fitted with the paddle attachment, add the butter and light brown sugar. Cream together until light and fluffy. Mix in the pumpkin puree and sourdough discard until the starter has fully dissolved into the mixture.
- Using a spatula (or with your mixer on the low setting), slowly add in the flour mixture and mix until combined.
- Using a large spoon or cookie scoop, fill the cupcakes three-quarters full.
- Bake for 19 to 21 minutes or until a toothpick inserted in the center comes out clean.
- To make the frosting: In the bowl of a stand mixer fitted with the paddle attachment (or using a hand mixer) add the butter, cream cheese, maple syrup, and powdered sugar. Mix on low until combined, then speed mixer up to high and whip for 1 to 2 minutes or until light and fluffy. Be sure to scrape down the sides of the bowl and paddle to mix thoroughly so you have a smooth texture.
- Transfer the frosting to a piping bag with Ateco tip #827.
- To make the topping: In a small bowl, add the cane sugar and cinnamon and stir to combine completely. Be sure to have this ready before frosting the cupcakes so when you sprinkle this on top, it sticks and the frosting hasn’t began to set yet.
- Pipe frosting onto each cupcake and sprinkle with the cinnamon and sugar mixture. Stick with a cinnamon stick (optional).
- Store in an airtight container in the fridge for up to 3 days.
Notes
- High Altitude — Bake for 18 to 20 minutes or until a toothpick inserted in the center comes out clean.
