1In a medium bowl, add the butter, honey, cinnamon, and vanilla.
2Beat with a whisk or an electric handheld mixer until well combined and fluffy.
3Set aside and keep at room temperature until ready to serve. You can store it in an airtight container in the refrigerator for up to one month.
4In a medium bowl, whisk together the flour, brown sugar, baking powder, baking soda, salt, cinnamon, and pumpkin pie spice (if using).
5In a separate large bowl, whisk together the buttermilk, pumpkin puree, eggs, melted and slightly cooled butter, and vanilla until smooth.
6Add the dry ingredient mixture to the wet, and whisk until just combined (it’s okay if the batter is a little lumpy).
7Set aside and allow the batter rest for 10-15 minutes (do NOT skip — this allows the flour to absorb the liquid, making the pancakes lighter and fluffier).
8While the batter is resting, prepare the cinnamon swirl mixture.
9In a small bowl, mix together the softened (almost melted) butter, sugar, cinnamon, and 2 tbsp of the pumpkin pancake batter until well combined and smooth.
10Transfer the mixture to a piping bag or a small sandwich baggie with a small portion of the corner snipped off. This is what you’re going to use to pipe the cinnamon swirl into the pancakes!
11Heat a large nonstick skillet or griddle over medium or medium-low heat (depending on how strong the heat from your stovetop is) and grease with butter (if needed).
12Use a large cookie scoop or 1/4 cup measuring cup to scoop and pour the pancake batter onto the skillet for each pancake.
13Let the pancakes cook on the pan for 1 minute.
14Then, using the piping bag full of the cinnamon swirl mixture, starting at the middle, gently swirl and create a spiral of the cinnamon swirl mixture into each pancake, pushing slightly into the batter.
15Cook for 2-4 minutes, until bubbles appear on the surface.
16Then use a spatula to gently flip the pancakes over, and cook on the other side for another 1-3 minutes, until golden and cooked through.
17Transfer the pancakes onto a baking sheet and keep warm in the oven at 200F while you make the rest of the pancakes.
18Once ready, serve the pancakes warm with the whipped honey cinnamon butter and maple syrup, if desired.
