Chocolate Almond-Flour Mug Cake

This is a weighed, single-mug chocolate cake built on blanched almond flour, cocoa and allulose. The microwave method calls for stirring early, standing off heat, and checking the center and several surrounding points for at least 165°F (74°C). 247-Keto has not kitchen-tested this recipe, so treat it as an editorial proposal and not as a result we have observed.

Food safety and allergens

The batter contains raw egg, so do not taste it. FDA notes that shell eggs can contain Salmonella, advises washing hands, utensils and surfaces after contact with raw eggs, and recommends cooking egg dishes thoroughly and using a food thermometer FDA egg safety guidance. Keep utensils that touched raw egg away from ready-to-eat food FoodSafety.gov food handling guidance.

Refrigerate perishable leftovers within two hours, or within one hour if the surrounding temperature is above 90°F (32°C), and keep the refrigerator at 40°F (4°C) or below FoodSafety.gov food handling guidance. Egg dishes that are reheated later should reach 165°F (74°C) FDA egg safety guidance.

This recipe contains almonds (a tree nut), egg and milk (from the butter). Read the current label on every ingredient, and do not assume any product is allergen-free from its name FDA food allergy guidance.

Practical notes

Use the superfine blanched almond flour named in the ingredient list, which the manufacturer describes as finely ground blanched almonds, rather than almond meal with skins Bob's Red Mill almond flour information. The leavener is double-acting baking powder; baking soda is not an equal-amount swap, so no soda alternative is given King Arthur baking powder and soda guidance. The sweetener is single-ingredient granulated allulose, and only that product identity is relied on here Selected allulose product ingredients.

Weigh the small amounts, such as the baking powder, vanilla and salt, on the scale rather than estimating them. Water is used instead of an almond drink, and there are no chocolate chips or frosting. Mix in the mug with a whisk, and use the oven mitt when moving the hot mug.

Microwave endpoint

This cake is heated in a microwave, so the endpoint is the microwave-specific one: FoodSafety.gov advises thoroughly microwaving food to 165°F (74°C) or above FoodSafety.gov microwave safety guidance. That is the single temperature used for this method.

Microwave heating can be uneven, so the method has three parts FoodSafety.gov microwave safety guidance:

• Stir early. Stir the batter during early heating, while it is still fluid and can be mixed.
• Let it stand off heat. Standing gives heat time to spread from hotter areas to colder ones.
• Check several points. Use the thin-tip thermometer at the center and at several surrounding points, keeping the probe clear of the mug's sides and bottom. If any point reads below 165°F (74°C), continue heating, let the mug stand, and check again.

Color and appearance are not a substitute for the thermometer. This formula has no validated heating time, standing time or wattage schedule, so none is given; your appliance and the checks decide when the cake is done.

Evidence limit

247-Keto has not kitchen-tested this recipe, so finished yield, heating and standing time, texture, storage quality and nutrition have not been measured, and no thermometer result has been observed.

Ingredients

• 21 g Bob's Red Mill superfine blanched almond flour
• 5 g unsweetened natural cocoa powder
• 20 g pure granulated allulose
• 1 g double-acting baking powder
• 50 g raw whole egg, shell removed
• 21 g unsalted butter, melted
• 15 g drinking water
• 1 g pure vanilla extract
• 0.25 g fine salt

Equipment

• Digital scale
• 350–400 mL microwave-safe mug without metal decoration
• Whisk
• Microwave
• Thin-tip thermometer
• Oven mitt

Method

1. Confirm that the mug is microwave-safe and appropriate for the intended heating. Mix almond flour, cocoa, allulose, baking powder and salt in it.
2. Whisk in the weighed egg, melted butter, water and vanilla until no dry ingredient remains unmixed. Leave space above the batter and keep the mug unsealed.
3. Microwave on high using short checking intervals appropriate to your appliance. Stop during early heating and stir the batter while it is still fluid, then continue heating; this formula has no validated microwave duration or wattage schedule.
4. Continue heating until no wet raw batter remains. Let the mug stand off heat so heat can spread from hotter areas to colder areas, then check the center and several surrounding points with a thin-tip thermometer for at least 165°F (74°C), keeping the probe clear of the mug. Continue heating and repeat the standing and checks if any checked point is below 165°F (74°C). Do not taste raw batter or use color alone as the check.
5. Remove using an oven mitt and let the mug cool enough to handle before eating. No finished volume, serving number or cake texture has been measured.
