Gather your ingredients. You’ll need fresh grapes, sugar, flour, butter, eggs, vanilla extract, and lemon juice.
Rinse the fresh grapes under cold water, remove stems, and pat dry.
Preheat your oven to 350°F (175°C).
In a bowl, combine flour, sugar, and any spices. Whisk together.
Cream together the butter and sugar until light and fluffy.
Beat in the eggs one at a time, followed by vanilla extract and lemon juice.
Gradually add the dry mixture to the wet ingredients, stirring gently.
Fold in the prepared grapes gently.
Transfer the mixture into a greased baking dish.
Bake in the preheated oven for the time specified in your recipe, until a toothpick comes out clean.
Allow to cool for a few minutes before serving.
