    Step 16. Bake the Gateau Breton for 50 to 55 minutes until the top is a medium brown. Cover loosely with foil if it is browning too quickly. Cool to lukewarm. Go around the edges of the pan with a small metal spatula and turn out. Cool completely on a rack.

    NOTE: If the pastry is very soft coming from the processor, chill it just until firm enough to press in and roll out. Do not let it get completely hard or the large amount of butter in the pastry will make it difficult to roll out.

    Variation

    • Substitute dried apricot for the prunes if desired.

    Storage

    The pastry will keep for at least 5 days at room temperature if kept covered.

    Gateau Breton

    Chef: Helen S Fletcher
    Gateau Breton is a French pastry that comes from the Bretagne region of France.  While professional looking, this easily made pastry features salted European butter and a prune or apricot filling between two layers of pastry made in a food processor or mixer. 
    Prep Time 1 hr
    Cook Time 55 mins
    Total Time 1 hr 55 mins

    Ingredients
      

    Prune Filling

    • 4 ounces dried prunes
    • ⅓ cup water
    • 2 tablespoons dark rum
    • 1 tablespoon butter cut into several small pieces (15 grams or ½ ounce)
    • ¼ cup powdered sugar
    • 1 teaspoon vanilla

    Gateau Breton Pastry

    • 1 cup salted European style butter cold (225 grams or 8 ounces)
    • 6 large egg yolks
    • 2 cups all-purpose flour ((280 grams or 10 ounces)
    • 1 cup granulated sugar (200 grams or 7 ounces)

    Instructions
     

    Prune Filling

    • Place the prunes, water and dark rum in a small pan.  Bring it to a boil and cook until most of the water has evaporated. 
    • Remove it from the heat and mash the prunes with the back of a spoon until smooth.  Don’t worry if a few small pieces are left.  
    • And the remaining ingredients, stirring until the butter melts and all is combined.  Set aside to cool completely.

    Gateau Breton Pastry

    • Line an 8” round cake pan with parchment paper.  Spray the paper and entire cake pan with a non-stick baking release.  Set aside.   
    • Using the round pan, draw an 8” circle in the middle of a piece of parchment paper.  Turn it over and set aside. Preheat the oven to 350F.  
    • Cut the butter into small pieces and keep refrigerated until using.   
    • Reserve one egg yolk for the finish.  Place it in a small bowl and cover it directly with plastic wrap.  
    • Combine the flour and sugar in the bowl of a food processor.   Pulse to combine.  
    • Add the cold butter and process until it is indistinguishable.   
    • Add five egg yolks and process until the dough comes together.   Scrape down. 
    •  Rearrange the dough in the processor as needed so it comes together
    • Remove the dough from the processor.  
    • Clean the blade by pulsing several times.  
    • Bring the dough together in one piece.  It will be soft at this point.  Do not add flour to the work surface.  Just use a gentle motion to bring it together.  It will weigh about 770 grams or about 27 ounces.  Divide it in half or about 385 grams each or 13 ½ ounces each. Shape into discs. 
    • If the dough is too soft to work, chill it for about 2 hours or so until it firms up.  Do not let it get too hard or it will be difficult to press in and roll out. 
    • Place one disc in the middle of the pan.  Cover it with plastic wrap and press it out evenly to cover the bottom of the pan. 
    • Spread the filling to within about ¾ inch from the sides.  
    • Place the second disc of pastry in the middle of the circle on the parchment paper.  Place another piece of parchment or waxed paper over the pastry and roll out to fit within the 8” circle.   
    • Flip the paper over so the bottom is on top.  If the pastry does not exactly fit, adjust it now. 
    • Chill just until firm but not hard, about 10 to 15 minutes. 
    • In the meantime, stir a teaspoon of water into the reserved egg yolk.
    • Dampen the edges of the bottom piece of pastry with water and place the top over the filling.  Press the top and bottom edges together lightly.  
    • Apply the egg wash to the top of the cake.  Using a fork, draw a cross hatch on the top layer. 
    • Bake for 50 to 55 minutes until the top is a medium brown.  Cover with foil if it browns too quickly.  
    • Cool to lukewarm, go around the edges of the pan with a small metal spatula and turn the gateau out.  Cool completely right side up.   

    Notes

    Alternate Apricot Filling for the Gateau Breton:  Substitute dried apricots for the prunes in the filling above.
    The filling makes a great spread for toast or English muffins.

      As I prepare to make this, I noticed the pan size is 9” in the steps, but 8” in the recipe. Which size do you recommend?

        Hi Denise - it should be an 8" round cake pan. I corrected the recipe. Thanks for calling my attention to this.

      Haven't tasted it yet but it looks amazing and was very easy to make with the recipe. The rolling out top pastry step made it simple to assemble. The only thing I couldn't find was the baking temperature, I guessed standard 180°C and it looks like that worked.

        Thank you so much for this. I read, and reread but sometimes you just go right over one of the most important parts. So happy though that the directions and photos worked out for you.

        I read and re-read but I apparently I skipped one of the most important directions. You are correct 350°F/180°C is the temperature. So happy the directions and photos helped you make a perfect Gateau Breton. Thanks so much for letting me know so I could get this into the directions.

      Hello Helen -
      This, like all your recipes, looks fabulous. I do have a problem with receiving your blog - it always goes to my junk mail, no matter how many times I have tried to re-subscribe. Am I missing something?
      Hope somebody can help me.
      Cheers,

      Oh, this is PERFECT timing for our Canadian Thanksgiving this weekend! I've been fishing around for a special dish, Helen, and I think this looks just right. And, as always, your clear and precise instructions combined with endlessly helpful photos of the process along the way means I'm ok with tackling a new recipe with company coming. Thank you!

      Mmm I love this and have not had it in a long time. My husband does not like dried fruit of any kind, especially prunes. If I make it for myself you know I will eat the whole thing. So its best to make it for company right? What other fillings have you made this with?
      It looks fabulous. Thank you as always.

        Hi Rocky - I've only made it with prunes but dried apricots can be substituted. Also, I've seen it with jam, particularly cherry. There are some excellent fillings in mThe Marvelous Variable Kolachey Kolache post. One recipe of any of the fillings will be enough as long as you use an 8" pan. As to eating the whole thing, cut it into pieces and freeze the pieces so you can have a treat whenever. There's always a work around Rocky. Hope you survived Ian with no damage.
