Step 1
Preheat your oven to 350°F.
Step 2
Line a muffin tin with grease-proof muffin liners in a color of your choice (remember, they are going to be on display).
Step 3
Beat the butter and sugar together until pale and creamy, then stir in the eggs and almonds, and then the lemon zest and juice.
Step 4
Sift the gluten-free flour and baking powder into this mixture; add the polenta flour, and stir gently until combined.
Step 5
Carefully spoon the mixture into the muffin liners, being careful not to spill any on the sides. Only fill them halfway (to allow room for the icing).
Step 6

Bake for 20 minutes or until the cupcakes are firm to the touch. If in doubt, gently test with a skewer: if it comes out clean, they are done. (The cakes will have risen but will still be below the tops of the muffin liners.)
Step 7

Transfer to a wire rack and allow to cool completely. Frost with gluten-free frosting.
Step 9
