Instructions

Step 1

Preheat the oven to 350°F and prepare a 9 x 13 inch rectangular pan with butter and parchment paper.

Step 2

In a medium bowl, whisk together the flour, poppy seeds, baking powder, baking soda, and salt.

Step 3

In a separate large bowl, use an electric mixer to beat together the butter, sugar, and lemon zest.

Step 4

When the mixture is light and fluffy, add in the eggs one by one. When fully combined, pour in half of the dry mixture into the batter and mix until just combined. Pour in the buttermilk, lemon juice, and vanilla bean paste, and continue to mix. Then add in the remaining dry mixture. Mix until fully combined and no flour pockets remain.

Step 5

Pour into your prepared pan and bake for 25-35 minutes, or until an inserted toothpick comes out clean.

Step 6

Let cool on a wire rack while preparing the frosting.

Step 7

To prepare the frosting, whip the softened cream cheese and butter together for 4-1o mins (depending on how fluffy you want your frosting).

Step 8

While whipping, blend the freeze dried berries to make a fine powder.

Step 9

Sift the confectioners sugar and berry powder into the whipped frosting.

Step 10

Beat for a minute, or however long it takes for the confectioners sugar to fully incorporate.
