Lemon Blackberry Danish Ricotta Puff Pastry Pinwheels Step-by-step instructions

Before you start

Before starting, heat the oven to 400°F (200°C) and line a baking sheet with parchment paper. Thaw the puff pastry according to package directions—usually in the refrigerator for a few hours or on the counter for 30 minutes.

Grate the lemon white chocolate and set it aside. Have the ricotta, lemon curd, blackberries, and vanilla icing measured and ready. Keep the pastry cold until the last minute to ensure the best flake.

Instructions

Prep and Fill

1. 1Prepare the Pastry and Chocolate
   Heat the oven to 400°F (200°C). Line a baking sheet with parchment paper. Unfold the thawed puff pastry on a lightly floured surface. Use a sharp knife to score the corners of each square, cutting about 1 inch from each corner diagonally toward the center, creating a pinwheel pattern. Grate the lemon white chocolate on the large holes of a box grater into fine curls and set aside.
   Look for The pastry squares are scored but not cut all the way through; the chocolate is grated into small curls.
   Tip Keep the pastry cold while working to ensure the best flake.
2. 2Mix the Ricotta Filling
   In a small bowl, stir the ricotta until smooth and creamy. If the ricotta is very thick, add a teaspoon of milk to loosen it slightly, but keep it thick enough to hold its shape when spooned.
   Look for The ricotta is smooth and spreadable but not runny.
   Tip Use whole-milk ricotta for the creamiest texture.

At this point, the pastry squares are scored and the filling is ready. The ricotta should be smooth and the lemon curd glossy. The blackberries are washed and dried. The oven is preheated. Everything is in place for quick assembly.

Shape and Top

3. 3Assemble the Pinwheels
   Place the scored pastry squares on the prepared baking sheet. Spoon a generous tablespoon of ricotta into the center of each square, then top with a spoonful of lemon curd. Gently fold alternating corners of each square inward, overlapping them over the filling to form a pinwheel shape. Press the corners gently to seal.
   Look for The pinwheels are formed with the filling visible in the center.
   Tip Do not overfill; the pastry needs room to puff.
4. 4Add the Blackberries
   Press 3 or 4 plump blackberries into the exposed ricotta and lemon curd on top of each pinwheel, gently nestling them into the filling.
   Look for Blackberries sit snugly in the filling without sinking in completely.
   Tip Use dry blackberries to prevent excess juice from making the pastry soggy.

The pinwheels are formed with the filling visible in the center and the blackberries nestled on top. The pastry corners are folded neatly. The baking sheet is ready to go into the oven. The pinwheels look neat and inviting.

Bake and Glaze

5. 5Bake the Pinwheels
   Bake in the preheated oven for 16 to 18 minutes, until the pastry is puffed and deep golden brown. The filling should be bubbling gently around the edges.
   Look for The pastry is golden and flaky, and the filling is hot and bubbling.
   Tip Rotate the baking sheet halfway through for even browning.
6. 6Finish and Serve
   Transfer the baking sheet to a wire rack and let the pinwheels cool for 5 minutes. Drizzle the vanilla icing over the warm pinwheels, then sprinkle with the grated lemon white chocolate curls. Serve warm, lifting a flaky portion with a spatula.
   Look for The icing is drizzled and the chocolate curls are scattered over the top.
   Tip For a cleaner drizzle, use a spoon or a piping bag.

The pinwheels are golden brown and puffed. The filling is hot and bubbly. After cooling slightly, they are drizzled with icing and sprinkled with chocolate curls. The aroma of butter and lemon fills the kitchen.

Common mistakes

One common mistake is overfilling the pastry, which can cause the filling to leak out during baking. Keep the filling to about a tablespoon of ricotta and a teaspoon of curd per square.

Another pitfall is letting the pastry get too warm; if it becomes sticky, chill it in the freezer for 10 minutes before baking. Also, avoid pressing the corners too firmly—just gentle pressure is enough to hold the shape.

How to tell it’s done

The pinwheels are done when the pastry is puffed and deep golden brown all over, and the filling is hot and bubbling slightly around the edges.

A skewer inserted into the center should come out clean, and the pastry should feel crisp to the touch.

If the edges brown too quickly, cover loosely with foil. Let them cool for a few minutes before adding the icing, so it doesn't melt completely into the pastry.
