How to Make My Homemade High Protein Snickers Mug Cake

Time needed: 2 minutes

Mix Ingredients
In a small bowl or mug, whisk together peanut butter, maple syrup, milk, Snickers protein powder, almond flour, cocoa powder, baking powder, and salt until a thick, smooth batter forms.
Add peanuts
Fold in chopped peanuts.
Add caramel, optional
Swirl your quick caramel drizzle on top.
Microwave
Microwave for 40–60 seconds, until the top looks set but still slightly gooey in the center. Alternatively, you can bake in the oven in an oven safe dish or ramekin at 350F for 10 minutes.
Cool and add chocolate
Let cool 1–2 minutes before enjoying. While cooling, melt chocolate and coconut oil together in the microwave for 30 seconds. Top with melted dark chocolate, additional crushed peanuts and sea salt.

Storage

I like to eat mug cakes fresh, but you can store the dry ingredients in an airtight container for up to 6 months. When you’re ready, just add the wet ingredients, microwave, and enjoy!

Recipe Tips for the Best Protein Snickers Protein Mug Cake

Don’t overcook: A slightly gooey center is best for mug cakes. They can become dry if overcooked. Mine was ready at 45 seconds.
Oven option: Bake at 350°F (175°C) for 10–12 minutes.
Make sure to use a large mug that has plenty of room for the cake to rise as it cooks. I like to use a soup mug to make mine.

Variations

Vegan: Use plant-based protein powder and non-dairy milk.
Keto-friendly: Swap maple syrup for allulose or erythritol-based syrup.
Nut-free: Use a nut free protein powder, sunflower seed butter instead of peanut butter and skip the peanuts.
Protein Powder: I used Snickers because I had it on hand, but you could also use chocolate or a chocolate caramel or chocolate peanut butter flavored powder.

Frequently Asked Questions

I don’t have Snickers protein powder, can I use another flavor of protein powder?

Yes! Chocolate peanut butter or chocolate caramel flavors work well, but you can use any protein powder of your choosing.

Can I make this Snickers mug cake in advance?

Mug cakes are best fresh, but you can mix the dry ingredients ahead of time, and add the wet when ready to microwave it.

How do I make my protein mug cake fudgier?

To get a super fudgy mug cake, slightly undercook it and fold in extra chocolate chips.

Can I bake my Snickers protein mug cake instead of microwaving it?

Yes! Bake at 350°F (175°C) for 10–12 minutes for a firmer texture.
