- Almond Flour - I used unblanched almond flour in this recipe which is why you can see the little specks of brown from the skin of the almonds. It gives a bit of a nuttier flavor and texture than blanched almond flour. Blanched almond flour will work as well.
- Coconut Flour - I use a bit of coconut flour to balance the almond flour since it can be naturally oily.
- Sweetener - My blend of xylitol, erythritol, and stevia works well in this but I do offer other ideas in the recipe card.
- Butter - For a dairy free option you can sub in coconut oil.
- Yogurt - Use coconut cream in place of the sour cream if you need to avoid dairy.
- Egg - Egg is the binder in this recipe and is necessary for a cake texture.
- Baking Powder - Always check that it is fresh so your baked goods rise properly.
- Vanilla Extract - A must when baking. Vanilla enhances the flavor of just about everything.
- Cranberries - Fresh or frozen work equally well.
How to Make a Healthy Mug Cake
It’s so simple, even your kids could make it themselves (and they probably will)! I chose to use cranberries in this mug cake, but you can sub in any fruit, berries, or omit. More variations are below the recipe and complete measurements are in the recipe card.
Step One: Put all the ingredients in a medium-sized mug or large ramekin.
Step Two: Stir together. Make sure to mix the cake batter well.
Step Three: Microwave. Enjoy!
- Fruit - Any fruit will work but if you are using a firm fruit like apple I recommend softening it first. You can just microwave chopped apples with a bit of water until they soften and then proceed with the rest of the recipe.
- Chocolate - Add sugar free chocolate chips, chocolate chunks, or leave it plain and then drizzle with some chocolate syrup later on.
- Nuts - Chopped nuts are a nice addition to this healthy mug cake. Walnuts, pecans, and almonds can be added.
- Spices - Pumpkin spice, apple pie spice, cinnamon, ginger, cloves, cardamom, or nutmeg are nice choices for a warm flavor.
- Herbs - No, I'm not crazy. Adding a tiny bit of rosemary will enhance the flavor of this whole cake. Or try the classic combination of lemon and lavender by adding some finely chopped lavender and lemon zest.
- Frosting - Adding icing turns mug cakes into cupcakes. This one is delicious with my keto cream cheese frosting. Or stir together some maple syrup, a dash of vanilla extract, and a little almond butter or other nut butter and spread that on the top.
- Reduced Calorie Option: Sub in Trim Healthy Mama Baking Blend for the almond and coconut flours. The first ingredient in their blend is oat fiber which is gluten-free and has fewer calories than both almond and coconut.
Can I make this without a microwave?
If you don't have a microwave handy this quick-cooking cake can also be made in the oven! Just bake at 350 for about 20 minutes until it is firm to the touch. Now that's what we call versatile.
Can I use frozen cranberries?
Absolutely. You can see that mine are still a little frosty on the plate. Just cut them in half and add them still frozen.
Can I use an egg substitute?
Possibly. I haven't tested this with any of the egg substitutes or vegan options out there so I can't promise they will work.
