This Strawberry Rhubarb Poke Cake is a fun and easy dessert that is perfect for summer. The cake is moist and tender, with a sweet and tangy filling of fresh strawberries and rhubarb. The whipped cream topping adds a nice lightness and creaminess to the cake. To make the cake, simply mix together the dry ingredients, cream the butter and sugar, and then add the eggs and vanilla. Pour the batter into a greased baking dish, poke holes in the top with a fork, and pour a mixture of sweetened condensed milk and strawberry rhubarb sauce over the top. Chill the cake for a few hours, then top with whipped cream before serving.
