Best Royal-Inspired Biscuit Recipes for National Biscuit Day

National Biscuit Day is the perfect excuse to fire up the Aga and fill the kitchen with buttery, chocolatey aromas. Because an Aga delivers steady radiant heat, you can tackle fridge cakes, delicate shortbread and meringue-topped cinnamon stars without juggling hot spots or waiting for the oven to preheat.

Below you will find the royal-inspired recipes we love to make for friends, neighbours and showroom visitors across Yorkshire.

Why Bake Biscuits In An Aga?

• Constant warmth: The roasting oven holds a consistent 200–220 °C for golden edges, while the simmering oven keeps batches crisp without scorching.
• Two hotplates: Melt chocolate or butter gently on the simmering plate and flash-boil syrups on the boiling plate.
• Residual heat: Cooling trays on the closed lids or in the warming oven ensures biscuits set with perfect texture.

Recommended Aga Settings

Recipe 1: Chocolate Biscuit Cake

This iconic fridge cake leans on pantry staples yet feels celebratory. The Aga’s simmering plate makes melting a breeze.

1. Prep the tin: Line a 20 cm loose-bottom tin with Bake-O-Glide or baking paper.
2. Melt: Rest a heavy saucepan on the simmering plate. Melt 115 g butter with 115 g caster sugar and a splash of water, stirring until the sugar dissolves.
3. Add chocolate: Slide to the cooler edge of the plate and stir in 225 g 70% dark chocolate until smooth.
4. Fold: Tip in 225 g broken rich tea biscuits and mix until coated. Press firmly into the tin.
5. Chill: Place on a cold shelf or in the fridge for two hours.
6. Ganache finish: Warm 150 ml double cream on the simmering plate, pour over 150 g chopped chocolate, whisk glossy, spread over the cake and chill again before slicing.

Aga tip: If you have an electric Aga conversion in Yorkshire, switch the simmering plate to ECO mode once the chocolate melts to prevent scorching. If you have an oil or gas Aga then slide the pan to the cooler edge of the simmering plate or onto a cold shelf to keep the gentle heat.

Recipe 2: Royal Shortbread (Balmoral-style All-Butter Biscuits)

Rich, crumbly shortbread thrives on low, even heat. Use the simmering oven or a cold shelf in the roasting oven.

1. Cream: Beat 225 g soft unsalted butter with 100 g caster or icing sugar using a hand mixer plugged in near the Aga.
2. Mix: Gently work in 325 g plain flour, 25 g rice flour, and a pinch of salt. Stop as soon as the dough comes together.
3. Shape: Pat to 1 cm thick, cut rounds or fingers, and prick with a fork. Chill on the cold shelf for 15 minutes to hold shape.
4. Bake: Slide onto the lowest runners of the simmering oven (approx. 150 °C) for 35–40 minutes until pale gold.
5. Finish: Sprinkle with caster sugar and cool completely on a wire rack placed over the closed simmering plate.

Aga tip: If your cooker runs on oil or solid fuel, keep an eye on Aga running costs by batching multiple trays while the oven is at temperature.

Recipe 3: Cinnamon Star Biscuits (Royal Christmas Favourite)

These chewy, spiced stars add sparkle to any biscuit tin. The roasting oven’s upper runners give you a crisp meringue glaze while the centres stay soft.

1. Meringue base: Whisk two egg whites with 200 g icing sugar and a teaspoon of lemon juice on the simmering plate using a heatproof bowl until glossy. Reserve 3 tablespoons for glazing.
2. Dough: Fold in 250 g ground almonds, 40 g blitzed mixed peel paste, zest of one lemon, 2 teaspoons cinnamon and a pinch of cloves to form a firm dough.
3. Roll: Sandwich the dough between baking paper sheets and roll to 5 mm thickness. Chill on the cold shelf for 20 minutes.
4. Cut: Use a star cutter and transfer to a lined baking tray.
5. Glaze: Brush with the reserved meringue.
6. Bake: Place on the third runners of the roasting oven (about 180 °C) for 10–12 minutes until the glaze is set but the centres remain tender. Cool on a rack.

Aga tip: Need to bake multiple trays? Rotate between the roasting oven and simmering oven so each batch gets a gentle finish.

FAQs

Can I use milk chocolate in the biscuit cake?

You can, but mix it with at least half dark chocolate so the cake sets firmly.

How do I stop shortbread from spreading?

Chill the dough on a cold shelf before baking and keep the simmering oven below 160 °C.

Do I need baking powder for cinnamon stars?

No as the beaten egg whites provide lift; over-baking will make them brittle.

What if my Aga runs hot?

Bake shortbread on a cold shelf or double up the baking trays to diffuse the heat.

Can I freeze any of these biscuits?

The chocolate biscuit cake freezes well after the ganache sets; shortbread dough can be frozen raw and baked from frozen with a few extra minutes.

How do I keep glacé icing white on cinnamon stars?

Use finely sifted icing sugar and bake on the middle runners to avoid browning the glaze.
