This gluten free tres leches cake is soaked in three milks for an incredibly moist, melt-in-your-mouth texture. It's a classic Latin American dessert everyone can enjoy.
Preheat oven to 350F and lightly grease a 9x13 inch baking dish.
In a bowl, whisk together the gluten free flour and baking powder. In a separate large bowl, beat the butter and sugar until fluffy. Add the eggs one at a time, then the vanilla.
Gradually mix the dry ingredients into the wet ingredients until just combined. Pour the batter into the prepared dish and bake for 25-30 minutes until a toothpick comes out clean. Let the cake cool slightly.
Whisk together the sweetened condensed milk, evaporated milk, and whole milk. Poke holes all over the top of the warm cake using a fork.
Pour the milk mixture slowly over the cake, allowing it to soak in. Cover and refrigerate for at least 4 hours, or overnight.
Before serving, whip the heavy cream and powdered sugar until stiff peaks form. Spread evenly over the chilled cake and dust with ground cinnamon.
