Baileys Red Velvet Tres Leches Cake

Preheat the oven to 350 degrees F. Grease an 8x8x2-inch baking dish; line the bottom with a parchment paper square.

In a small bowl, whisk the flour, baking powder, cinnamon, and salt. In a medium bowl, using an electric mixer on high speed, beat the sugar and eggs until very light and fluffy, 5 to 7 minutes. Add half of the dry ingredients. Beat on low speed just to blend. Beat in the milk, then the remaining dry ingredients, just until blended. Transfer to the cake pan; smooth the top.

Bake until the top springs back when pressed and a toothpick inserted into the center comes out clean, 25 to 30 minutes. Let cool in the pan on a wire rack for 15 minutes.
