Ingredients:
- 1/2 cup (115g) unsalted butter, softened
- 3/4 cup (150g) granulated sugar
- 2 large eggs, room temperature
- 1 tsp (5ml) vanilla extract
- 1/2 cup (130g) Biscoff cookie butter, softened
- 2 cups (250g) all-purpose flour
- 1 1/2 tsp (7g) baking powder
- 1 tsp (2g) ground cinnamon
- 1/4 tsp (1.5g) salt
- 1/2 cup (120ml) whole milk, room temperature
- 1 cup (225g) unsalted butter, softened
- 1/2 cup (130g) Biscoff cookie butter
- 3 cups (360g) powdered sugar, sifted
- 2 tbsp (30ml) heavy cream
- 1 tsp (5ml) vanilla extract
- 1 pinch salt
- 1/4 cup (60g) Biscoff cookie butter, melted
- 10 Biscoff cookies
Instructions:
- Beat the softened butter and sugar together until pale and fluffy. Add eggs one at a time, beating well after each addition.
- Stir in the softened Biscoff spread and vanilla extract until the mixture is a uniform mahogany color.
- Sift together flour, baking powder, cinnamon, and salt. Gradually add the dry ingredients to the wet, alternating with the milk. Mix on low speed just until combined.
- Divide the batter evenly among 20 lined cupcake tins, filling each about 2/3 full.
- Bake at 350°F (175°C) for 18–20 minutes until a toothpick inserted into the center comes out clean.
- Let the cupcakes rest in the pan for 5 minutes before transferring them to a wire rack to cool completely.
- Use a small knife or apple corer to remove the center of each cooled cupcake and spoon in a dollop of melted Biscoff spread.
- Beat butter and Biscoff spread until smooth. Slowly add powdered sugar in batches, then stir in heavy cream, vanilla, and salt. Beat on high for 2 minutes.
- Pipe a generous swirl of Biscoff buttercream frosting onto each cake and top with a Biscoff cookie garnish.
