Ingredients for this Funfetti Mug Cake:

Butter: Butter adds richness and flavor to the mug cake, making it moist and tender. It also helps to create a tender crumb and contributes to the overall flavor. If you don’t have butter or want a dairy free alternative, go for refined coconut oil or vegan butter.

Agave Nectar: Agave nectar is a natural sweetener that is derived from the agave plant. It is a low glycemic alternative to sugar and adds natural sweetness to the mug cake. Feel free to sub in honey or maple syrup if you prefer!

Egg: The egg provides structure and stability to the mug cake, helping it to rise and hold its shape. It also contributes to the flavor and moisture content of the cake.

Vanilla Extract: Vanilla extract adds a warm, sweet, and subtle flavor to the mug cake, enhancing the overall taste and aroma.

Blanched Almond Flour: Blanched almond flour is a gluten-free flour that is made from ground almonds. It is a great alternative to wheat flour and adds a nutty flavor and moist texture to the mug cake.

Oat Flour: Oat flour is a gluten-free flour made from oats that have been ground. It helps to absorb moisture and provides structure to the mug cake, making it more stable.

Baking Powder: Baking powder is a leavening agent that helps the mug cake to rise and become fluffy. It also contributes to the overall texture of the cake.

Salt: Salt enhances the flavor of the mug cake and balances the sweetness. It also helps to bring out the flavors of the other ingredients.

Sprinkles: Sprinkles add a fun and festive touch to the mug cake, making it perfect for special occasions or just a sweet treat. They also contribute to the texture and add a pop of color to the cake.

What to Serve on Top:

Personally I ate my mug cake exactly as it is without any toppers, but here are some ideas if you want to add something on top:

Whipped Cream: A dollop of whipped cream adds a light and creamy texture to the mug cake, and the sweetness pairs deliciously with the sprinkles.

Ice Cream: A scoop of vanilla takes the funfetti mug cake to the next level, creating a rich and creamy dessert.

Frosting: A swirl of frosting, either store-bought or homemade, adds a sweet and rich layer to the mug cake, and you can even get creative and use different flavors.

How to Store Leftovers

I’m not going to lie, this is best eaten right away! But, if you have leftovers, here’s how I’d do it. Cover your mug with plastic wrap or transfer to an airtight container and store in the fridge. Reheat in the microwave for about 30 seconds until heated through.

Can I Make this in the oven?

Sure thing! Place the batter into ramekins or overproof dishes. Place them on a baking sheet to keep them even and bake at 350F for about 15+ minutes until the edges puff up and the centers are set!
