You can make your own buckwheat our in your Thermomix® from scratch. Place 250 g raw buckwheat groats into mixing bowl and mill 2 min/speed 10 to a ne consistency. Store the leftover our in a sealable container in your freezer or refrigerator to preserve its nutrient content and keep it fresh for longer.
If you don’t have any raw cacao on hand, you can use regular cocoa powder instead.
For gluten-free cupcakes, be sure to choose a gluten-free brand of baking powder. All remaining ingredients are gluten free.
If you would prefer a lower fructose option, you can replace the maple syrup with rice malt syrup.
You can also use activated or roasted hazelnuts instead of raw, if preferred.
You can use homemade Hazelnut chocolate spread for these cupcakes or store-bought. Homemade spread is the much healthier option, as commercial spreads tend to contain mainly sugar and vegetable oil. Store-bought spreads also tend to be much sweeter, so you’re unlikely to need the stevia in the cupcake mixture if you’re using one.
