You can't go wrong with both pumpkin and chocolate in one, fluffy muffin! I love to add in some chocolate chunks for a special morning treat or afternoon pick-me-up!
Preheat your oven to 375 °F and grease or line 12 muffin cups.
In a large mixing bowl, make your flax eggs by whisking together the ground flaxseed and water. Allow it to sit for 5 minutes to thicken.
To the flax eggs, add in the wet ingredients and spices, from the pumpkin puree to the sea salt. Whisk until smooth.
Add in the flour and most of the chocolate chips, reserving some for the tops of the muffins, and stir until just combined.
Using a spoon, divide half of the batter among the 12 muffin cups.
Stir the cocoa powder into the remaining pumpkin batter and then evenly distribute the chocolate batter on top of the pumpkin batter, filling up each muffin cup to the top.
Bake for 20 minutes. Allow the muffins to cool for a couple minutes in the pan before removing them to cool completely on a wire rack.
Once cooled completely, these muffins store wonderfully in an airtight container in the fridge for up to a week. Alternatively, you could wrap them individually and freeze them. To reheat a frozen muffin, simply unwrap it and microwave it straight from frozen for a couple minutes until heated through.
Notes
*Instead of all the individual spices, you can just use 2 teaspoons of pumpkin pie spice if you have that on hand. **I haven't tested this yet, but I'm sure Bob's Red Mill's 1-to-1 Gluten Free Baking Flour would work great instead of the whole wheat flour if you needed these muffins to be gluten free.
