    Sometimes you want cake, and you want it now, and baking a whole one for yourself is a bit much. This gluten-free vanilla mug cake takes about five minutes start to finish, most of which is stirring. It uses our Vanilla Cake Mix scaled down to a single serving, with just enough egg and oil to give it a proper soft, tender crumb rather than the rubbery texture mug cakes are notorious for. Use a plant milk and it is gluten-free and dairy-free. Add a spoonful of sprinkles and you have a birthday cake for one. So good, no one will guess it is gluten-free, the way Pamela's has done it since 1988.

    Why you'll love it

    • About five minutes, with one minute of that in the microwave.
    • One mug, one spoon, and nothing to wash but that.
    • A real cake crumb, because it is scaled from our own cake recipe rather than shortcut into something gummy.
    • Gluten-free and dairy-free when made with a plant milk.
    • A blank canvas. Sprinkles, lemon, cinnamon, chocolate chips, or a scoop of protein powder.

    Do you need a special gluten-free mug cake mix?

    No, and that is the nicest part. Single-serve mug cake mixes are expensive and hard to find gluten-free. A 21 ounce bag of Pamela's Gluten-Free Vanilla Cake Mix makes dozens of mug cakes for a fraction of the cost, and it doubles as an actual cake mix whenever you want the full-size version. Keep a bag in the pantry and dessert for one is always about five minutes away.

    Prep Time 3 minutes
    Cook Time 1 minute
    Total Time about 5 minutes
    Serving Size 1 mug cake

    Ingredients

    • 1/2 cup (60 g) Pamela's Gluten-Free Vanilla Cake Mix
    • 1 tablespoon beaten egg (beat 1 large egg and measure out a tablespoon)
    • 2 teaspoons neutral oil, such as canola or avocado
    • 1 tablespoon milk, dairy or non-dairy, plus a little more if needed
    • Optional: 1 tablespoon sprinkles, chocolate chips, or a spoonful of jam
    Shop Gluten-Free Vanilla Cake Mix, 21 oz.

    Directions

    • Lightly grease a wide, microwave-safe mug or small bowl that holds at least 12 ounces. The cake will roughly double as it cooks, so do not fill it more than halfway.
    • Beat a whole egg in a small bowl, then measure 1 tablespoon of it into the mug. Save the rest for another use, or double the recipe and make two.
    • Add the oil and milk to the mug and stir to combine. Add the Vanilla Cake Mix and stir until you have a smooth, thick batter with no dry pockets in the bottom corners. If it is too stiff to stir smooth, add another teaspoon of milk. Stir in any add-ins now.
    • Microwave on high for 70 seconds. The cake will puff up and then settle. If the top still looks wet, add 10 seconds at a time. Do not overcook it, since that is what makes mug cakes dry.
    • Let it sit for a minute, then eat it straight from the mug, or run a knife around the edge and turn it out onto a plate.

    Recipe Tips & Notes

    Microwaves vary a lot. Seventy seconds is the starting point for a 1000-watt microwave. Pull it slightly underdone rather than over; you can always add ten seconds, but you cannot undo a dry mug cake.

    To keep it gluten-free: Pamela's Gluten-Free Vanilla Cake Mix is GFCO-certified gluten-free. It is also labeled dairy-free, and since this recipe uses oil rather than butter, a non-dairy milk makes the whole mug cake dairy-free.

    How to keep a mug cake from turning out dry

    Mug cakes go dry for one reason, which is too long in the microwave. The batter is small enough that ten seconds makes a visible difference, so start at seventy and add in small increments. Pull it while the very top still looks a touch damp, because it keeps cooking in the hot mug for a minute after. The oil in this recipe helps too, which is exactly why it is there.

    What kind of mug should you use?

    Wide and roomy beats tall and narrow every time. The batter roughly doubles before it settles, so a narrow mug sends it over the rim. Use a mug that holds at least 12 ounces, or honestly, a small cereal bowl, and fill it no more than halfway. Make sure whatever you use is microwave-safe, with no metallic trim.

    Variations

    • Birthday cake: stir a spoonful of rainbow sprinkles into the batter and top with more. This is the one to photograph.
    • Chocolate: use Pamela's Gluten-Free Chocolate Cake Mix in place of the vanilla. Everything else stays the same.
    • Lemon: add the zest of half a lemon to the batter and a squeeze of juice to the glaze.
    • Cinnamon roll: add 1/4 teaspoon cinnamon to the batter and drizzle with a simple glaze.
    • Chocolate chip or cookies and cream: stir in a tablespoon of chocolate chips, or crushed gluten-free chocolate sandwich cookies.
    • Jam-filled: drop a teaspoon of jam into the center of the batter before microwaving.
    • Protein mug cake: stir in about 15 g of your preferred protein powder and an extra tablespoon of milk, since protein powder absorbs liquid.
    • Frosted: whisk 2 tablespoons powdered sugar with a teaspoon of milk and spoon it over the warm cake.

    Make ahead & storage

    • Mug cakes are a make-and-eat recipe. They are best within a few minutes of coming out of the microwave and turn firm as they cool.
    • To prep ahead, portion the dry mix into small jars or bags so all you add is the wet ingredients. These make good gifts and dorm care packages.
    • Leftovers keep covered in the refrigerator for a day. Reheat for about 10 seconds.

    Stir 1 tablespoon of beaten egg, 2 teaspoons of oil, and 1 tablespoon of milk in a wide, microwave-safe mug, then mix in 1/2 cup of Pamela's Gluten-Free Vanilla Cake Mix until smooth. Microwave about 70 seconds.

    Yes. Pamela's Gluten-Free Vanilla Cake Mix is labeled dairy-free and this recipe uses oil rather than butter, so a plant milk such as oat, almond, or soy makes the whole mug cake dairy-free.

    Almost always because it cooked too long. Start at 70 seconds and add 10 seconds at a time, pulling it while the top still looks slightly damp, since it keeps cooking in the hot mug.

    A wide, microwave-safe mug holding at least 12 ounces, filled no more than halfway. The batter roughly doubles before settling, so a tall narrow mug will overflow. A small bowl works well too.

    Beat a whole large egg in a small bowl first, then measure out 1 tablespoon. Refrigerate the rest for a day, or double the recipe and make two mug cakes using 2 tablespoons.
