Easter Mug Cake with Marshmallow Peeps

Marshmallow Peeps and migrating birds.
What do these things have in common?
They are both signs of spring!
As soon as I spot those chubby buddies in the grocery store, I get excited for gardening and bike rides, and Easter egg hunts.

I love creating mug cakes for each occasion or holiday.
We already have this Halloween eyeball mug cake, and this pink and chocolatey Valentine’s mug cake.
Now we can add a sweet lemon-and-coconut-flavored Easter treat!

Marshmallow Peep Mug Cake Ingredients
This spring mug cake has all the bright flavors – lemon juice, lemon zest, flaked coconut, topped with a sweet Peep for cute factor (and gooey marshmallow deliciousness).
Here’s what you need:

all-purpose flour (or gluten-free all-purpose flour mix)
granulated sugar any kind: white, brown, coconut, erythritol or monk fruit for sugar-free (but you’ll be hard-pressed to find a sugar-free Peep)
baking powder
oil or melted butter or coconut oil (I used olive oil; any oil works)
any kind of milk you like
lemon zest and juice
1 big Marshmallow Peep
shredded coconut

For the Marshmallow Peep, the chick is preferred because the yellow goes with this lemon-flavored mug cake.
But the bunny is more than acceptable.
Let’s make this!
